AIUM Practice Guideline for the Performance of an Ultrasound Examination of the Abdomen and/orRetroperitoneum© 2008 by the American Institute of Ultrasound in MedicineI. IntroductionThe clinical aspects of this guideline (Indications/ Contraindications, Specifications for Individual Examinations, and Equipment Specifications) were developed collaboratively by the American Instituteof Ultrasound in Medicine (AIUM) and the American College of Radiology (ACR). Recommendations for personnel requirements, written request for the exami-nation, procedure documentation, and quality control vary between the two organizations and are addressed by each separately.This guideline has been developed to assist practitioners performing ultrasound studies of the abdomen and/or retroperitoneum. An ultrasound examination is a proven and useful procedure for the evaluation of many struc-tures within these anatomic areas. Depending on the clinical indications, an examination may include the entirety of the abdomen and/or retroperitoneum, a single organ, or several organs. A combination of struc-tures may be imaged because of the location (eg, upper abdominal scan and right upper quadrant organs) or function (eg, biliary system [liver, gallbladder, and bile ducts] and both kidneys). For some patients, more focused examinations may be appropriate for evaluating specific clinical indications or to follow a known abnor-mality. In some cases, additional and/or specialized examinations may be necessary (eg, spectral, color,and/or power Doppler). While it is not possible to detect every abnormality using an ultrasound examination of the abdomen and/or retroperitoneum, adherence to the following guideline will maximize the probabilityof detecting abnormalities.Throughout this guideline, references to Doppler evaluation may include spectral, color, or power Doppler individually or in any combination. Whenever a long-axis view is indicated, it couldbe either a sagittal or coronal plane.(For pediatric considerations, see sections V.A.2, V.A.5, V.B.3, and VII.)II.Qualifications and Responsibilities of PersonnelSee the AIUM Official Statement Training Guidelines for Physicians Who Evaluate and Interpret Diagnostic Ultrasound Examinations and the AIUM Standards and Guidelines for the Accreditation of Ultrasound Practices.III.Indications/Contraindications Indications for an ultrasound examination of the abdomen and/or retroperitoneum include but are not limited to:A.Abdominal, flank, and/or back pain.B.Signs or symptoms that may be referred from theabdominal and/or retroperitoneal regions such asjaundice or hematuria.C.Palpable abnormalities such as an abdominal massor organomegaly.D.Abnormal laboratory values or abnormal findingson other imaging examinations suggestive ofabdominal and/or retroperitoneal pathology.E.Follow-up of known or suspected abnormalities inthe abdomen and/or retroperitoneum.F.Search for metastatic disease or an occult primaryneoplasm.G.Evaluation of suspected congenital abnormalities.H.Abdominal trauma.I.Pre- and post-transplantation evaluation.J.Planning and guidance for an invasive procedure. K.Search for the presence of free or loculated peri-toneal and/or retroperitoneal fluid.An abdominal and/or retroperitoneal ultrasound examination should be performed when there is a valid medical reason. There are no absolute contraindi-cations.IV. Written Request for the Examination The written or electronic request for an ultrasound examination should provide sufficient information to allow for the appropriate performance and interpreta-tion of the examination.The request for the examination must be originated by a physician or other appropriately licensed health care provider or under their direction. The accompanying clinical information should be provided by a physician or other appropriate health care provider familiar with the patient’s clinical situation and should be consistent with the relevant legal and local health care facility requirements.Original copyright 1994; revised 2008, 2007, 2002—AIUM PRACTICE GUIDELINES—Abdomen and/or Retroperitoneum Ultrasound1V. Specifications for IndividualExaminationsDoppler ultrasound may be useful to differentiate vascular from nonvascular structures in any location. Measurements should be considered for any abnormal area.A. Abdomen1.LiverThe examination of the liver should include long-axis and transverse views. The liver parenchyma should be evaluated for focal and/or diffuse abnormalities. If pos-sible, the echogenicity of the liver should be compared with that of the right kidney. In addition, the following should be imaged:a.The major vessels in the region of the liver, includ-ing the inferior vena cava (IVC), the hepatic veins,the main portal vein, and, if possible, the right andleft branches of the portal vein.b.The hepatic lobes (right, left, and caudate) and, ifpossible, the right hemidiaphragm and the adjacent pleural space.c.For vascular examinations of the native or trans-planted liver, Doppler evaluation should be usedto document blood flow characteristics and bloodflow direction. The structures that may be examined include the hepatic arteries, hepatic veins, portalveins, the intrahepatic portion of the IVC, collateral venous pathways, and transjugular intrahepaticportosystemic shunt stents.2. Gallbladder and Biliary TractThe gallbladder evaluation should include long-axis and transverse views obtained in the supine position; other positions, such as left lateral decubitus, erect, and prone positions, may be necessary to evaluatethe gallbladder and its surrounding area completely, particularly when stones and/or sludge are observed. Measurements may aid in determining gallbladder wall thickening. If the patient presents with pain, ten-derness to transducer compression should be assessed. The intrahepatic ducts can be evaluated by obtaining views of the liver demonstrating the right and left branches of the portal vein. Doppler imaging may be used to differentiate hepatic arteries and portal veins from bile ducts. The intrahepatic and extrahepatic bile ducts should be evaluated for dilatation, wall thicken-ing, intraluminal findings, and other abnormalities. The size of the bile duct in the porta hepatis should bedocumented. When visualized, the distal common bile duct in the pancreatic head should be evaluated.A routine gallbladder examination should be conducted on an adequately distended gallbladder. In most cases, fasting for 8 hours before the examination will permit adequate distension of a normally functioning gallblad-der in adults and children. In infants and some adults, adequate distention may be achieved in less time.3. PancreasWhenever possible, all portions of the pancreas—head, uncinate process, body, and tail—should be identified. Orally administered water or a contrast agent may afford better visualization of the pancreas. The following should be assessed in the examination of the pancreas:a.Parenchymal abnormalities.b.The distal common bile duct in the region of thepancreatic head.c.The pancreatic duct for dilatation and any otherabnormalities, with dilatation confirmed bymeasurement.d.The peripancreatic region for adenopathy and/orfluid.4. SpleenRepresentative views of the spleen in long-axis and transverse projections should be obtained. Doppler imaging may be used to determine the presence and direction of flow in the splenic vein and artery. Splenic measurement may be helpful in assessing enlargement. Echogenicity of the left kidney should be compared to splenic echogenicity when possible. An attempt should be made to demonstrate the left hemidiaphragm and the adjacent pleural space.5. BowelThe bowel may be evaluated for wall thickening, dilatation, muscular hypertrophy, masses, and other abnormalities. Sonography of the pylorus and sur-rounding structures may be indicated in the evaluation of the vomiting infant. Compression sonography may be necessary to visualize the appendix or other bowel loops. Measurements may aid in determining bowel wall thickening. Color Doppler imaging may be done to assess blood flow.6. Peritoneal FluidEvaluation for free or loculated peritoneal fluid should include documentation of the extent and location of any fluid identified.Original copyright 1994; revised 2008, 2007, 2002—AIUM PRACTICE GUIDELINES—Abdomen and/or Retroperitoneum Ultrasound 2For evaluating peritoneal spaces for bleeding after traumatic injury, particularly blunt trauma, the exami-nation known as focused abdominal sonography for trauma (or focused assessment with sonography for trauma) may be performed.The objective of the abdominal portion of the examination is to analyze the abdomen for free fluid. Longitudinal and transverse plane images shouldbe obtained in the right upper quadrant through the area of the liver with attention to fluid collections peripheral to the liver and in the subhepatic space. Longitudinal and transverse plane images should be obtained in the left upper quadrant through the area of the spleen, with attention to fluid collections peripheral to the spleen. Longitudinal and transverse images should be obtained at the periphery of the left and right abdomen in the areas of the left and right paracolic gutters for evidence of free fluid. Longitudinal and transverse midline images of the pelvis are obtained to evaluate for free pelvic fluid. Analysis through a fluid-filled bladder (which if necessary can be filled through a Foley catheter when possible) may help in the evaluation of the pelvis. 7. Abdominal WallThe examination should include images of the abdominal wall in the location of symptoms or signs. The relationship of any identified mass to the peri-toneum should be demonstrated. Any defect in the peritoneum and abdominal wall musculature should be documented. The presence or absence of bowel, fluid, or other tissue contained within any abdominal wall defect should be noted. Images obtained in the upright position and/or with use of the Valsalva maneuver may be helpful. A Doppler examination may be useful to define the relationship of blood vessels to a detected mass.B. Retroperitoneum1. KidneysThe examination should include long-axis and trans-verse views of the upper poles, midportions, and lower poles of the kidneys. The cortex and renal pelvises should be assessed. A maximum measurement of renal length should be recorded for both kidneys. Decubitus, prone, or upright positioning may provide better images of the kidneys. When possible, renal echogenicity should be compared to echogenicity of the adjacent liver or spleen. The kidneys and perirenal regions should be assessed for abnormalities.For vascular examination of the kidneys, Doppler imaging can be used:a.T o assess renal arterial and venous patency.b.T o evaluate adults suspected of having renal arterystenosis. For this application, angle-adjustedmeasurements of the peak systolic velocity shouldbe made proximally, centrally, and distally in theextrarenal portion of the main renal arteries whenpossible. The peak systolic velocity of the adjacentaorta (or iliac artery in transplanted kidneys) shouldalso be documented for calculating the ratio of renalto aortic peak systolic velocity. Spectral Doppler evalu-ation of the intrarenal arteries from the upper andlower portions of the kidneys, obtained to evaluatethe early systolic peak, may be of value as indirectevidence of proximal stenosis in the main renal artery.2. Urinary Bladder and Adjacent StructuresWhen performing a complete ultrasound evaluation of the urinary tract, transverse and longitudinal images of the distended urinary bladder and its wall should be included, if possible. Bladder lumen or wall abnormalities should be noted. Dilatation or other distal ureteral abnormalities should be documented. Transverse and longitudinal scans may be used to demonstrate any postvoid residual, which may be quantitated and reported.3. Adrenal GlandsWhen possible, usually in the neonate or young infant, long-axis and transverse images of the adrenal glands may be obtained. The adrenal glands are infrequently seen in adults. When visualized, the size of the gland should be documented, as well as the presence of hem-orrhage, masses, or other abnormalities.4. AortaRepresentative images of the aorta in longitudinal and transverse planes should be obtained as appropriate. When evaluation of the aorta is specifically requested, see the AIUM Practice Guideline for the Performance of Diagnostic and Screening Ultrasound Examinations of the Abdominal Aorta.5. Inferior Vena CavaTransverse and longitudinal images of the IVC should be obtained. Patency and abnormalities may be evaluated with Doppler imaging. Vena cava filters, interruption devices, or catheters may need to be localized with respect to the hepatic and/or renal veins.Original copyright 1994; revised 2008, 2007, 2002—AIUM PRACTICE GUIDELINES—Abdomen and/or Retroperitoneum Ultrasound3VI. DocumentationAdequate documentation is essential for high-quality patient care. There should be a permanent record of the ultrasound examination and its interpretation. Images of all appropriate areas, both normal and abnormal, should be recorded. Variations from normal size should be accompanied by measurements. Images should be labeled with the patient identification, facility identifi-cation, examination date, and side (right or left) of the anatomic site imaged. An official interpretation (final report) of the ultrasound findings should be included in the patient’s medical record. Retention of the ultra-sound examination should be consistent both with clinical needs and with relevant legal and local health care facility requirements.Reporting should be in accordance with the AIUM Practice Guideline for Documentation of an Ultrasound Examination.VII. Equipment SpecificationsAbdomen and/or retroperitoneum ultrasound studies should be conducted with real-time scanners, preferably using sector or linear (straight or curved) transducers. The equipment should be adjusted to operate at the highest clinically appropriate frequency, realizing that there is a trade-off between resolution and beam pene-tration. For most preadolescent pediatric patients, mean frequencies of 5 MHz or greater are preferred, and in neonates and small infants, a higher-frequency trans-ducer is often necessary. For adults, mean frequencies between 2 and 5 MHz are most commonly used. When Doppler studies are performed, the Doppler frequency may differ from the imaging frequency. Diagnostic information should be optimized while keeping total ultrasound exposure as low as reasonably achievable. VIII. Quality Control and Improvement, Safety, Infection Control, and PatientEducation ConcernsPolicies and procedures related to quality control, patient education, infection control, and safety should be developed and implemented in accordance with the AIUM Standards and Guidelines for the Accreditation of Ultrasound Practices.Equipment performance monitoring should be in accordance with the AIUM Standards and Guidelines for the Accreditation of Ultrasound Practices.AcknowledgmentsThis guideline was developed by the American Institute of Ultrasound in Medicine (AIUM) in collaboration with the American College of Radiology (ACR), according to the process described in the AIUM Clinical Standards Committee Manual.Principal RevisersHarris L.

超声引导下神经阻滞的标准
超声引导下神经阻滞的标准Ultrasound-guided nerve blockade is a standard technique used in regional anesthesia to provide targeted pain relief during surgical procedures or for postoperative pain management. This procedure involves the use of ultrasound imaging to visualize the nerves and surrounding structures, allowing for precise needle placement and accurate delivery of local anesthetic agents. The following paragraphs will discuss the importance of ultrasound guidance in nerve blockade from various perspectives.From a patient's perspective, ultrasound-guided nerve blockade offers several advantages. Firstly, it enhances the safety of the procedure by minimizing the risk of complications such as accidental puncture of blood vessels or neighboring organs. The real-time visualization provided by ultrasound allows the anesthesiologist to accurately identify the target nerve and avoid potential hazards. This reduces the likelihood of adverse events and improves patient outcomes.Furthermore, ultrasound guidance improves the efficacyof nerve blockade. By visualizing the nerves andsurrounding tissues, the anesthesiologist can precisely target the nerve of interest and ensure optimal needle placement. This results in more effective anesthesia, leading to improved pain control and patient satisfaction. Additionally, ultrasound guidance allows for the deposition of local anesthetic agents in close proximity to the nerve, reducing the required dosage and minimizing systemic side effects.From the perspective of the anesthesiologist,ultrasound-guided nerve blockade offers increased accuracy and confidence during the procedure. Traditionally, nerve blocks were performed using landmark-based techniques,which relied on anatomical landmarks and palpation. However, these techniques are often imprecise and can lead to inconsistent results. With ultrasound guidance, the anesthesiologist can directly visualize the nerve, needle, and local anesthetic spread, ensuring accurate placementand optimal distribution of the anesthetic agent.Moreover, ultrasound guidance allows for real-time adjustments and refinements during the procedure. If the initial needle placement does not result in the desired spread of local anesthetic, the anesthesiologist can modify the approach and redirect the needle under direct visualization. This dynamic process ensures that the nerve blockade is performed with precision and adaptability, maximizing the chances of success.From a healthcare system perspective, ultrasound-guided nerve blockade has the potential to reduce healthcare costs. By improving the accuracy and efficacy of nerve blocks, ultrasound guidance can lead to better pain control and reduced reliance on systemic analgesics. This not only improves patient comfort but also decreases the length of hospital stays and the need for additional interventions. Additionally, the reduction in complications associatedwith nerve blockade performed without ultrasound guidance can result in cost savings by avoiding the need for subsequent treatments or interventions to address these complications.In conclusion, ultrasound-guided nerve blockade has become the standard technique for regional anesthesia due to its numerous benefits. From the patient's perspective, it enhances safety and improves pain control, leading to better outcomes and increased satisfaction. For the anesthesiologist, ultrasound guidance provides accuracy, confidence, and the ability to make real-time adjustments. From a healthcare system standpoint, ultrasound-guided nerve blockade has the potential to reduce costs by improving pain management and minimizing complications. Overall, this technique has revolutionized the field of regional anesthesia and continues to be a valuable tool in providing effective and safe pain relief.。

No. 07/844,732 filed Mar. 2, 1992, now U.S. Pat. No. 5,231,975 which is a divisional of application Ser. No. 07/484,560, now U.S. Pat. No. 5,115,805, filed Feb. 23, 1990.TECHNICAL FIELDThis invention relates generally to the field of drug delivery. More particularly, the invention relates to a method of enhancing the rate of permeation of topically, transmucosally or transdermally applied materials using high frequency ultrasound.BACKGROUNDThe delivery of drugs through the skin ("transdermal drug delivery" or "TDD") provides many advantages; primarily, such a means of delivery is a comfortable, convenient and non-invasive way of administering drugs. The variable rates of absorption and metabolism encountered in oral treatment are avoided, and other inherent inconveniences--e.g., gastrointestinal irritation and the like--are eliminated as well. Transdermal drug delivery also makes possible a high degree of control over blood concentrations of any particular drug.Skin is a structurally complex, relatively impermeable membrane. Molecules moving from the environment into and through intact skin must first penetrate the stratum corneum and any material on its surface. They must then penetrate the viable epidermis, the papillary dermis, and the capillary walls into the blood stream or lymph channels. To be so absorbed, molecules must overcome a different resistance to penetration in each type of tissue. Transport across the skin membrane is thus a complex phenomenon. However, it is the stratum corneum, a layer approximately 5-15 micrometers thick over most of the body, which presents the primary barrier to absorption of topical compositions or transdermally administered drugs. It is believed to be the high degree of keratinization within its cells as well as their dense packing and cementation by ordered, semicrystalline lipids which create in many cases a substantially impermeable barrier to drug penetration. Applicability of transdermal drug delivery is thus presently limited, because the skin is such an excellent barrier to the ingress of topically applied materials. For example, many of the new peptides and proteins now produced as a result of the biotechnology revolution cannot be delivered across the skin in sufficient quantities due to their naturally low rates of skin permeability.Various methods have been used to increase skin permeability, and in particular to increase the permeability of the stratum corneum (i.e., so as to achieve enhanced penetration, through the skin, of the drug to be administered transdermally). The primary focus has been on the use of chemical enhancers, i.e., wherein drug is coadministered with a penetration enhancing agent (or "permeation enhancer"). While such compounds are effective in increasing the rate at which drug is delivered through the skin, there are drawbacks with many permeation enhancers which limit their use. For example, many permeation enhancers are associated with deleterious effects on the skin (e.g., irritation). In addition, control of drug delivery with chemical enhancement can be quite difficult.Iontophoresis has also been used to increase the permeability of skin to drugs, and involves (1) the application of an external electric field, and (2) topical delivery of an ionized form of drug (or of a neutral drug carried with the water flux associated with ion transport, i.e., via "electroosmosis"). While permeation enhancement via iontophoresis has, as with chemical enhancers, been effective, there are problems with control of drug delivery and the degree of irreversible skin damage induced by the transmembrane passage of current.The presently disclosed and claimed method involves the use of ultrasound to decrease the barrier function of the stratum corneum and thus increase the rate at which a drug may be delivered through the skin. "Ultrasound" is defined as mechanical pressure waves with frequencies above 20,000 Hz (see, e.g., H. Lutz et al., Manual of Ultrasound: 1. Basic Physical and Technical Principles (Berlin: Springer-Verlag, 1984)).As discussed by P. Tyle et al. in Pharmaceutical Research 6(5):355-361 (1989), drug penetration achieved via "sonophoresis" (the movement of drugs through skin under the influence of an ultrasonic perturbation; see D. M. Skauen and G. M. Zentner, Int. J. Pharmaceutics 20:235-245 (1984)), is believed to result from thermal, mechanical and chemical alteration of biological tissues by the applied ultrasonic waves. Unlike iontophoresis, the risk of skin damage appears to be low.Applications of ultrasound to drug delivery have been discussed in the literature. See, for example: P. Tyle et al., supra (which provides an overview of sonophoresis); S. Miyazaki et al., J. Pharm. Pharmacol. 40:716-717 (1988) (controlled release of insulin from a polymer implant using ultrasound); J. Kost et al., Proceed. Intern. Symp. Control. Rel. Bioact. Mater.16(141):294-295 (1989) (overview of the effect of ultrasound on the permeability of human skin and synthetic membranes); H. Benson et al., Physical Therapy 69(2):113-118 (1989) (effect of ultrasound on the percutaneous absorption of benzydamine); E. Novak, Arch. Phys. Medicine & Rehab. 45:231-232 (1964) (enhanced penetration of lidocaine through intact skin using ultrasound); J. E. Griffin et al., Amer. J. Phys. Medicine 44(1):20-25 (1965) (ultrasonic penetration of cortisol into pig tissue); J. E. Griffin et al., J. Amer. Phys. Therapy Assoc.46:18-26 (1966) (overview of the use of ultrasonic energy in drug therapy); J. E. Griffin et al., Phys. Therapy 47(7):594-601 (1967) (ultrasonic penetration of hydrocortisone); J. E. Griffin et al., Phys. Therapy 48(12):1336-1344 (1968) (ultrasonic penetration of cortisol into pig tissue); J. E. Griffin et al., Amer. J. Phys. Medicine 51(2):62-72 (1972) (same); J. C. McElnay, Int. J. Pharmaceutics 40:105-110 (1987) (the effect of ultrasound on the percutaneous absorption of fluocinolone acetonide); and C. Escoffier et al., Bioeng. Skin 2:87-94 (1986) (in vitro study of the velocity of ultrasound in skin).In addition to the aforementioned art, U.S. Pat. Nos. 4,767,402 and 4,780,212 to Kost et al. relate specifically to the use of specific frequencies of ultrasound to enhance the rate of permeation of a drug through human skin or through a synthetic membrane.While the application of ultrasound in conjunction with drug delivery is thus known, results have for the most part been disappointing, i.e., enhancement of skin permeability has been relatively low.SUMMARY OF THE INVENTIONThe present invention provides a novel method for enhancing the rate of permeation of a given material through a selected intact area of an individual's body surface. The method comprises contacting the selected intact area with the material and applying ultrasound to the contacted area. The ultrasound preferably has a frequency of above about 10 MHz, and is continued at an intensity and for a period of time sufficient to enhance the rate of permeation of the material into and through the body surface. The ultrasound can also be used to pretreat the selected area of the body surface in preparation for drug delivery, or for diagnostic purposes, i.e., to enable non-invasive sampling of physiologic material beneath the skin or body surface.In addition to enhancing the rate of permeation of a material, the present invention involves increasing the permeability of a biological membrane such as the stratum corneum by applying ultrasound having a frequency of above about 10 MHz to the membrane at an intensity and for a period of time sufficient to give rise to increased permeability of the membrane. Once the permeability of the membrane has been increased, it is possible to apply a material thereto and obtain an increased rate of flow of the material through the membrane.It is accordingly a primary object of the invention to address the aforementioned deficiencies of the prior art by providing a method of enhancing the permeability of biological membranes and thus allow for an increased rate of delivery of material therethrough.It is another object of the invention to provide such a method which is effective with or without chemical permeation enhancers.It is still another object of the invention to minimize lag time in such a method and provide a relatively short total treatment time.It is yet another object of the invention to provide such a method in which drug delivery is effected using ultrasound.It is a further object of the invention to enable sampling of tissue beneath the skin or other body surface by application of high frequency (>10 MHz) ultrasound thereto.A further feature of the invention is that it preferably involves ultrasound of a frequency greater than about 10 MHz.Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.BRIEF DESCRIPTION OF THE DRAWINGSFIGS. 1A, 1B and 1C are theoretical plots of energy dissipation within the skin barrier versus frequency of applied ultrasound.FIGS. 2, 3 and 4 are graphic representations of the amount of salicylic acid recovered from the stratum corneum after ultrasound treatment at different frequencies.FIGS. 5 and 6 represent the results of experiments similar to those summarized in FIGS. 2, 3 and 4, but with a shorter treatment time.FIGS. 7, 8, 9 and 10 are plots of enhancement versus "tape-strip number," as described in the Example.FIG. 11 illustrates the effect of ultrasound on the systemic availability of salicylic acid following topical application.DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSBefore the present method of enhancing the rate of permeation of a material through a biological membrane and enhancing the permeability of membranes using ultrasound are disclosed and described, it is to be understood that this invention is not limited to the particular process steps and materials disclosed herein as such process steps and materials may, of course, vary. It is alto to be understood that the terminology used herein is used for purpose of describing particular embodiments only and is not intended to be limiting since the scope of the present invention will be limited only by the appended claims.It must be noted that as used in this specification and the appended claims, the singular forms "a", "an" and "the" include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to "a drug" includes mixtures of drugs and their pharmaceutically acceptable salts, reference to "an ultrasound device" includes one or more ultrasound devices of the type necessary for carrying out the present invention, and reference to "the method of administration" includes one or more different methods of administration known to those skilled in the art or which will become known to those skilled in the art upon reading this disclosure.In one aspect of the invention a method is provided for enhancing the permeation of a given material such as a drug, pharmacologically active agent, or diagnostic agent into and/or through a biological membrane on an individual's body surface, which method comprises: (a) contacting the membrane with the chosen material in a pharmacologically acceptable carrier medium; and (b) applying ultrasound of an intensity and for a treatment time effective to produce delivery of the material through the membrane. The material is preferably a drug and it is preferable to obtain a desired blood level of the drug in the individual. The ultrasound is of a frequency and intensity effective to increase the permeability of the selected area to theapplied drug over that which would be obtained without ultrasound. The ultrasound preferably has a frequency of more than 10 MHz, and may be applied either continuously or pulsed, preferably continuously. The ultrasound may be applied to the skin either before or after application of the drug medium so long as administration of the ultrasound and the drug medium is relatively simultaneous, i.e., the ultrasound is applied within about 6, more preferably within about 4, most preferably within about 2 minutes of drug application.The invention is useful for achieving transdermal permeation of pharmacologically active agents which otherwise would be quite difficult to deliver through the skin or other body surface. For example, proteinaceous drugs and other high molecular weight pharmacologically active agents are ideal candidates for transdermal, transmucosal or topical delivery using the presently disclosed method. In an alternative embodiment, agents useful for diagnostic purposes may also be delivered into and/or through the body surface using the present method.The invention is also useful as a non-invasive diagnostic technique, i.e., in enabling the sampling of physiologic material from beneath the skin or other body surface and into a collection (and/or evaluation) chamber.The present invention will employ, unless otherwise indicated, conventional pharmaceutical methodology and more specifically conventional methodology used in connection with transdermal delivery of pharmaceutically active compounds and enhancers.In describing the present invention, the following terminology will be used in accordance with the definitions set out below.A "biological membrane" is intended to mean a membrane material present within a living organism which separates one area of the organism from another and, more specifically, which separates the organism from its outer environment. Skin and mucous membranes are thus included."Penetration enhancement" or "permeation enhancement" as used herein relates to an increase in the permeability of skin to a material such as a pharmacologically active agent, i.e., so as to increase the rate at which the material permeates into and through the skin. The present invention involves enhancement of permeation through the use of ultrasound, and, in particular, through the use of ultrasound having a frequency of greater than 10 MHz."Transdermal" (or "percutaneous") shall mean passage of a material into and through the skin to achieve effective therapeutic blood levels or deep tissue therapeutic levels. While the invention is described herein primarily in terms of "transdermal" administration, it will be appreciated by those skilled in the art that the presently disclosed and claimed method also encompasses the "transmucosal" and "topical" administration of drugs using ultrasound. "Transmucosal" is intended to mean passage of any given material through a mucosal membrane of a living organism and more specifically shall refer to the passage of a materialfrom the outside environment of the organism, through a mucous membrane and into the organism. "Transmucosal" administration thus includes delivery of drugs through either nasal or buccal tissue. By "topical" administration is meant local administration of a topical pharmacologically active agent to the skin as in, for example, the treatment of various skin disorders or the administration of a local anaesthetic. "Topical" delivery can involve penetration of a drug into the skin but not through it, i.e., topical administration does not involve actual passage of a drug into the bloodstream."Carriers" or "vehicles" as used herein refer to carrier materials without pharmacological activity which are suitable for administration with other pharmaceutically active materials, and include any such materials known in the art, e.g., any liquid, gel, solvent, liquid diluent, solubilizer, or the like, which is nontoxic and which does not interact with the drug to be administered in a deleterious manner. Examples of suitable carriers for use herein include water, mineral oil, silicone, inorganic gels, aqueous emulsions, liquid sugars, waxes, petroleum jelly, and a variety of other oils and polymeric materials.By the term "pharmacologically active agent" or "drug" as used herein is meant any chemical material or compound suitable for transdermal or transmucosal administration which can either (1) have a prophylactic effect on the organism and prevent an undesired biological effect such as preventing an infection, (2) alleviates a condition caused by a disease such as alleviating pain caused as a result of a disease, or (3) either alleviates or completely eliminates the disease from the organism. The effect of the agent may be local, such as providing for a local anaesthetic effect or it may be systemic. Such substances include the broad classes of compounds normally delivered through body surfaces and membranes, including skin. In general, this includes: anti-infectives such as antibiotics and antiviral agents; analgesics and analgesic combinations; anorexics; antihelminthics; antiarthritics; antiasthmatic agents; anticonvulsants; antidepressants; antidiabetic agents; antidiarrheals; antihistamines; antiinflammatory agents; antimigraine preparations; antinauseants; antineoplastics; antiparkinsonism drugs; antipruritics; antipsychotics; antipyretics; antispasmodics; anticholinergics; sympathomimetics; xanthine derivatives; cardiovascular preparations including potassium and calcium channel blockers, beta-blockers, and antiarrhythmics; antihypertensives; diuretics; vasodilators including general coronary, peripheral and cerebral; central nervous system stimulants; cough and cold preparations, including decongestants; hormones such as estradiol and other steroids, including corticosteroids; hypnotics; immunosuppressives; muscle relaxants; parasympatholytics; psychostimulants; sedatives; and tranquilizers. By the method of the present invention, both ionized and nonionzed drugs may be delivered, as can drugs of either high or low molecular weight.Proteinaceous and polypeptide drugs represent a preferred class of drugs for use in conjunction with the presently disclosed and claimed invention. Such drugs cannot generally be administered orally in that they Are often destroyed in the G.I. tract or metabolized in the liver. Further, due to the high molecular weight of most polypeptide drugs, conventional transdermal delivery systems are not generally effective. It is also desirable to use the methodof the invention in conjunction with drugs to which the permeability of the skin is relatively low, or which give rise to a long lag-time (application of ultrasound as described herein has been found to significantly reduce the lag-time involved with the transdermal administration of most drugs).By a "therapeutically effective" amount of a pharmacologically active agent is meant a nontoxic but sufficient amount of a compound to provide the desired therapeutic effect. The desired therapeutic effect may be a prophylactic effect, in preventing a disease, an effect which alleviates a system of the disease, or a curative effect which either eliminates or aids in the elimination of the disease.As noted above, the present invention is a method for enhancing the rate of permeation of a drug through an intact area of an individual's body surface, preferably the human skin. The method involves transdermal administration of a selected drug in conjunction with ultrasound. Ultrasound causes thermal, mechanical and chemical alterations of biological tissue, thereby enhancing the rate of permeation of a given material therethrough.While not wishing to be bound by theory, applicants propose that the use of higher frequency ultrasound as disclosed herein specifically enhances the permeation of the drug through the outer layer of skin, i.e., the stratum corneum, by causing momentary and reversible perturbations within (and thus short-term, reversible reduction in the barrier function of) the layer of the stratum corneum. It will be appreciated by those skilled in the art of transdermal drug delivery that a number of factors related to the present method will vary with the drug to be administered, the disease or injury to be treated, the age of the selected individual, the location of the skin to which the drug is applied, and the like.As noted above, "ultrasound" is ultrasonic radiation of a frequency above 20,000 Hz. As may be deduced from the literature cited above, ultrasound used for most medical purposes typically employs frequencies ranging from 1.6 to about 10 MHz. The present invention, by contrast, employs ultrasound frequencies of greater than about 10 MHz, preferably in the range of about 15 to 50 MHz, most preferably in the range of about 15 to 25 MHz. It should be emphasized that these ranges are intended to be merely illustrative of the preferred embodiment; in some cases higher or lower frequencies may be used.The ultrasound may be pulsed or continuous, but is preferably continuous when lower frequencies are used. At very high frequencies, pulsed application will generally be preferred so as to enable dissipation of generated heat.The preferred intensity of the applied ultrasound is less than about 5.0 W/cm.sup.2, more preferably is in the range of about 0.01 to 5.0 W/cm.sup.2, and most preferably is in the range of 0.05 to 3.0 W/cm.sup.2. The total treatment time, i.e., the period over which drug and ultrasound are administered, will vary depending on the drug administered, the disease or injury treated, etc., but will generally be on the order of about 30 seconds to 60 minutes, preferably 5 to 45 minutes, more preferably 5 to 30 minutes, and most preferably 5 to 10minutes. It should be noted that the aforementioned ranges represent suggested, or preferred, treatment times, but are not in any way intended to be limiting. Longer or shorter times may be possible and in some cases desirable. Virtually any type of device may be used to administer the ultrasound, providing that the device is callable of producing the higher frequency ultrasonic waves required by the present method. A device will typically have a power source such as a small battery, a transducer, a reservoir in which the drug medium is housed (and which may or may not be refillable), and a means to attach the system to the desired skin site.As ultrasound does not transmit well in air, a liquid medium is generally needed to efficiently and rapidly transmit ultrasound between the ultrasound applicator and the skin. As explained by P. Tyle et al., cited above, the selected drug medium should contain a "coupling" or "contacting" agent typically used in conjunction with ultrasound. The coupling agent should have an absorption coefficient similar to that of water, and furthermore be nonstaining, nonirritating to the skin, and slow drying. It is clearly preferred that the coupling agent retain a paste or gel consistency during the time period of ultrasound administration so that contact is maintained between the ultrasound source and the skin. Examples of preferred coupling agents are mixtures of mineral oil and glycerine and propylene glycol, oil/water emulsions, and a water-based gel. A solid-state, non-crystalline polymeric film having the above-mentioned characteristics may also be used. The drug medium may also contain a carrier or vehicle, as defined alone.A transdermal patch as well known in the art may be used in conjunction with the present invention, i.e., to deliver the drug medium to the skin. The "patch", however, must have the properties of the coupling agent as described in the preceding paragraph so as to enable transmission of the ultrasound from the applicator, through the patch, to the skin.As noted earlier in this section, virtually any chemical material or compound suitable for transdermal, transmucosal or topical administration may be administered using the present method. Again, the present invention is particularly useful to enhance delivery of proteinaceous and other high molecular weight drugs.The method of the invention is preferably carried out as follows. The drug medium, i.e., containing the selected drug or drugs in conjunction with the coupling agent and optionally a carrier or vehicle material, is applied to an area of intact body surface. Ultrasound preferably having a frequency greater than about 10 MHz may be applied before or after application of the drug medium, but is preferably applied immediately before application of the drug so as to "pretreat" the skin prior to drug administration.It should also be pointed out that the present method may be used in conjunction with a chemical permeation enhancer as known in the art, wherein the ultrasound enables the use of much lower concentrations of permeation enhancer--thus minimizing skin irritation and other problems frequently associated with such compounds--than would be possible in the absence of ultrasound. The permeation enhancer may be incorporated into the drug medium or it may。

周围神经超声英文著作
周围神经超声英文著作Peripheral Nerve Ultrasound: A Valuable Tool in Diagnosis and TreatmentPeripheral nerve ultrasound has emerged as a powerful diagnostic and therapeutic tool in the field of neurology and musculoskeletal medicine. This non-invasive imaging technique allows healthcare professionals to visualize the structure and function of peripheral nerves with remarkable clarity and precision. By leveraging the principles of sound wave propagation, peripheral nerve ultrasound enables clinicians to identify pathologies, guide interventions, and monitor the progress of various neurological and musculoskeletal conditions.One of the primary applications of peripheral nerve ultrasound is the evaluation of nerve entrapment syndromes. Conditions such as carpal tunnel syndrome, cubital tunnel syndrome, and peroneal nerve entrapment can be accurately diagnosed using this imaging modality. Ultrasound allows healthcare providers to assess the size, shape, and echogenicity of the affected nerves, as well as identifyany structural abnormalities or compression points. This information is invaluable in guiding the appropriate treatment approach, whether it be conservative management, targeted injections, or surgical intervention.In addition to nerve entrapment, peripheral nerve ultrasound has proven to be a valuable tool in the assessment of traumatic nerve injuries. By visualizing the anatomical integrity of the nerve, clinicians can determine the extent of the injury and plan the most effective treatment strategy. Ultrasound can help differentiate between complete nerve transection, partial nerve injury, and neuroma formation, allowing for more accurate prognosis and tailored rehabilitation protocols.Another area where peripheral nerve ultrasound has demonstrated its utility is in the evaluation of peripheral neuropathies. Conditions such as diabetic neuropathy, Charcot-Marie-Tooth disease, and chronic inflammatory demyelinating polyneuropathy can be characterized using this imaging technique. Clinicians can assess nerve size, echogenicity, and vascularity to identify patterns of nerve involvement and monitor disease progression or response to treatment.Beyond diagnostic applications, peripheral nerve ultrasound has also become an essential tool in the realm of interventional painmanagement. Ultrasound-guided nerve blocks and injections have become increasingly common, allowing for more precise and targeted delivery of anesthetic or corticosteroid agents. This technique reduces the risk of complications and improves the efficacy of these procedures, leading to better patient outcomes.The versatility of peripheral nerve ultrasound extends to the field of rehabilitation as well. Clinicians can use this imaging modality to guide the placement of neuromuscular electrical stimulation electrodes, ensuring optimal nerve-muscle interaction and improving the effectiveness of rehabilitation programs. Additionally, ultrasound can be employed to monitor the recovery and regeneration of nerves following injury or surgical intervention, providing valuable feedback to guide the rehabilitation process.One of the key advantages of peripheral nerve ultrasound is its accessibility and ease of use. Unlike other imaging modalities, such as magnetic resonance imaging (MRI) or computed tomography (CT), ultrasound equipment is relatively portable and can be readily available in clinical settings. This allows for rapid, bedside evaluation of peripheral nerve pathologies, enabling timely diagnosis and prompt initiation of appropriate treatment.Furthermore, peripheral nerve ultrasound is a cost-effective alternative to more expensive imaging techniques. This is particularlyrelevant in resource-limited settings or healthcare systems with budgetary constraints, where the availability of advanced imaging modalities may be limited. The affordability and portability of ultrasound equipment make it a valuable tool in expanding access to high-quality neurological and musculoskeletal care.Despite its numerous advantages, it is important to recognize that the success of peripheral nerve ultrasound is heavily dependent on the expertise and experience of the healthcare provider performing the examination. Proper training and ongoing education are crucial to ensure accurate interpretation of ultrasound images and the appropriate application of this technology in clinical practice.In conclusion, peripheral nerve ultrasound has emerged as a transformative diagnostic and therapeutic tool in the field of neurology and musculoskeletal medicine. Its ability to visualize the structure and function of peripheral nerves with remarkable clarity has revolutionized the way healthcare professionals approach the assessment and management of a wide range of neurological and musculoskeletal conditions. As the technology continues to evolve and the body of evidence supporting its clinical utility grows, the role of peripheral nerve ultrasound in modern healthcare is poised to expand further, ultimately leading to improved patient outcomes and enhanced quality of care.。

超声引导下甲状腺细针穿刺对甲状腺乳头状癌的诊断价值
我国甲状腺癌在近30年时间里发病率提高了近30倍,且发病人群趋于年轻化[1]。
最常见的甲状腺恶性肿瘤即甲状腺乳头状癌(PTC ),占总发病率的80%以上[2]。
PTC 早期缺乏特征性临床症状,患者无明显躯体不适,因而难以实现早期诊断。
随着超声技术的不断发展,以其为基础的多种诊断技术获得广泛运用,超声引导下甲状腺细针穿刺(US-FNAC )是近年来兴起的对可疑癌结节进行诊断的技术,具有创伤小、操作简单、无针道转移等优势[3]。
既往研究显示,US-FNAC 对甲状腺结节诊断的敏感度达到97.0%;但由于甲状腺结节大小、硬化、囊性病变等不同,穿刺医生操作熟练度差异以及癌结节声像图多样化等因素,US-FNAC 的准确率及阳性率均会受到一定影响[4]。
对于采用US-FNAC 对PTC 进行诊断的相关报道尚不多见,且多为笼统分析,未根据病灶尺寸进行分级探究[5]。
为探究US-FNAC 对于PTC 的诊Diagnostic value of ultrasound-guided fine needle aspiration for papillary thyrid carcinomaDING Wenjun,LIN Fengchun,TAO Yakui,SUN Jianwei,ZHANG Yu Department of Ultrasound,Hefei BOE Hospital,Hefei 230011,China摘要:目的探讨超声引导下甲状腺细针穿刺(US-FNAC )对甲状腺乳头状癌的诊断价值。

超声英文文献分享以下是一篇关于超声的英文文献分享:Title: The Use of Ultrasound in the Management of Thyroid NodulesUltrasound (US) is a widely used imaging modality that provides valuable information in the evaluation and management of thyroid nodules. US allows for the identification and characterization of thyroid nodules, evaluation of nodule vascularity, and guidance for fine-needle aspiration (FNA). In this article, we discuss the role of US in the diagnosis and management of thyroid nodules, including its advantages, limitations, and future directions.US is a noninvasive, radiation-free, and cost-effective imaging modality that provides real-time information about thyroid nodules. It can identify small nodules that are often missed on palpation and assess the morphology, size, echogenicity, calcifications, and vascularity of thyroid nodules. US-guided FNA is a minimally invasive technique that allows for the histopathological diagnosis of thyroidnodules. It has replaced surgical biopsy as the reference standard for the diagnosis of thyroid nodules.US can be used to differentiate benign from malignant thyroid nodules with variable accuracy. Malignant thyroid nodules are often hypoechoic, have irregular borders, microcalcifications, and increased vascularity on Doppler US. However, there is significant overlap between benign and malignant thyroid nodules on US features, leading to false positives and false negatives. Therefore, US cannot be used alone to diagnose thyroid malignancy.US-guided FNA is indicated for the evaluation of thyroid nodules with suspicious US features or a diameter greater than 1 cm. The Bethesda System for Reporting Thyroid Cytopathology is a widely used classification system for reporting FNA results. It categorizes thyroid nodules as benign, atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS), follicular neoplasm or suspicious for follicular neoplasm (FN/SFN), suspicious for malignancy (SM), or malignant. The risk of malignancy varies with the FNA category and informs clinical management decisions.Management options for thyroid nodules include observation, US-guided FNA, or surgical excision. Management decisions should be individualized based on the risk of malignancy, patient preferences, and local resources. Observation is recommended for benign thyroid nodules with low risk of malignancy. US-guided FNA is indicated for thyroid nodules with suspicious US features or a diameter greater than 1 cm. Surgical excision is indicated for cytologically malignant thyroid nodules or those with high suspicion of malignancy based on US features or growth on serial US surveillance.In conclusion, US plays a crucial role in the evaluation and management of thyroid nodules. It provides valuable information about the morphology and vascularity of thyroid nodules and can guide FNA for histopathological diagnosis. However, US features overlap between benign and malignant thyroid nodules, limiting its diagnostic accuracy. Therefore, US should be used in conjunction with other clinical factors and cytological findings to optimize the diagnosis and management of thyroid nodules. Future research should focus on improving US technology and developing more accurate algorithms for thyroid nodule diagnosis.。

Materials and Methods A total of 17 patients (19 lesions) with AWE who underwent MWA in Beijing Friendship Hospital from August 2014 to June 2023 were retrospectively analyzed. Grey-scale and color Doppler flow ultrasonography, and contrast-enhanced ultrasonography were used to observe the lesions before and after treatment. The AWE lesion volume, volume reduction rate, pain relief, and complications were recorded 3, 6, and 12 months after treatment to evaluate the treatment efficacy. Results Contrast-enhanced ultrasound showed that all lesions underwent successful treatment with single MWA. The average initial nodule volume was (7.46±5.82) ml, which decreased significantly to (4.32±2.76) ml, (2.47±1.68) ml, (1.72±1.16) ml at 3, 6 and 12 months follow-up (t=0.423, P=0.005; t=0.198, P=0.001; t=0.556, P=0.002) with a mean volume reduction rate of (46.18±24.36)%, (61.43±18.72)%, (74.25±13.26)%, respectively. Notably, all 17 patients experienced a significant decrease or complete alleviation of periodic abdominal incision pain at 12-month after treatment. One patient experienced local skin burns after the procedure, while the remaining patients did not experience severe complications. Conclusion MWA is safe and effective for treating AWE, and further research is warranted.【Key words】Endometriosis; Microwave; Ablation techniques; UltrasonographyChinese Journal of Medical Imaging, 2024, 32 (3): 279-283腹壁子宫内膜异位症(abdominal wall endometriosis,AWE)是子宫内膜腺体和间质出现于腹壁的一种最常见的盆腔外子宫内膜异位症[1-2]。

Repeated fluoroscopy, with more than 30 shots on average, is inevitable to ensure its accuracy and safety. However, exposure to X-rays may pose a threat to human health. We herein report a case of ultrasound (US)-assisted PELD in two levels of LDH to explore a new possibility that can reduce the radiation dose during puncture and cannulation in PELD.CASE SUMMARYA 38-year-old man with low back pain and left leg pain for more than 7 years came to our clinic, his symptoms had aggravated for 1 month, and he was diagnosed with L3-4 and L4-5 disc herniations. He received US-guided PELD with good results: His straight leg elevation increased from 40 to 90 degrees after PELD, and his visual analog scale (VAS) and Oswestry Disability Index scores both significantly decreased immediately and 6 mo after PELD. With the guidance of US, he received only two shots of fluoroscopy (fluoroscopic time: 4.4 s; radiation dose: 3.98 mGy). To our knowledge, this is the first case of US-guided puncture and cannulation of PELD for LDH at two levels.CONCLUSIONUS could be used to guide PELD and has the potential to largely reduce radiation than traditional X-ray guidance.Key words: Ultrasound; Endoscopic lumbar discectomy; Lumbar disc herniation; Radiation; Guidance; Case reportopen-access article which wasselected by an in-house editor andfully peer-reviewed by externalreviewers.

With the help of ultrasound (US) guidance, we report a patient with two levels of LDH who received only two shots to achieve satisfactory results. US guidance has great potential to become an alternative method to reduce radiation largely.Citation: Zhang MB, Yan LT, Li SP, Li YY, Huang P.

Fluoroscopy, to ensure the accuracy of puncture and cannulation, is inevitable. However, radiation exposure with X-ray guidance of PELD may be of concern because of its deleterious effects for both patients and surgeons.Therefore, an image guiding system without X-ray is needed to perform PELD.Ultrasound (US) is a real-time dynamic imaging facility with no ionizing radiation.We herein report a case of US-assisted PELD on a 38-year-old man with two levels ofLDH at the same time. Our successful experience may contribute to the application of US-guided PELD in the future.CASE PRESENTATIONA 38-year-old man [height: 174 cm; weight: 74.5 kg; body mass index (BMI): 24.6kg/m 2] with low back pain and left leg pain for more than 7 years and aggravatedsymptoms for 1 mo came to our hospital.History of present and past illnessHis previous history and family history were negative. He had lameness on his leftleg.Physical examinationPhysical examination showed tenderness and percussion pain radiation to the left legfrom the left part of the L4-S1 vertebral spinous processes. Dermal sensation in his leftlateral leg and left foot was decreased. Left straight leg raising and strengthening testhad positive results (40 degrees).Imaging examinationsX-ray showed small curvature of the lumbar spine. Computed tomography (CT) andmagnetic resonance imaging (MRI) showed L3-4 and L4-5 disc herniations (leftmargin type) (Figure 1).FINAL DIAGNOSIS The patient was diagnosed with LDH of the L3-4 and L4-5 levels (left margin type).TREATMENTThe patient needed PELD of both L3-4 and L4-5 levels. Institutional approval forPELD was obtained from the ethics committee of our hospital, and the procedure inthis study was performed in accordance with the tenets of the Declaration of Helsinki.Zhang MB et al. Ultrasound-assisted endoscopic lumbar discectomyFigure 1 X-ray and computed tomography transverse images of the patient. A and B: X-ray images showingsmall curvature of the lumbar spine; C: Computed tomography (CT) image suggesting L3-4 disc herniation (blackarrow, left margin type); D: CT image suggesting L4-5 disc herniation (black arrow, left margin type).Written informed consent was obtained from the patient. A portable Mindray M9 USsystem (Mindray, Shenzhen, China) with a C5-1S convex array transducer (centralfrequency: 5 MHz) was used in this study. The patient laid in a prone position on aradiolucent table with a pillow under his belly. One US physician with more than 4years of experience in interventional US performed the US guidance. First, alongitudinal section was used to display the transverse processes, and the lowesttransverse process was L5. Second, the probe was rotated by 90 degrees to display theL5 transverse process. The probe was moved upward, and the soft tissue in theintervertebral foramen of L4-5 appeared as a circular hyperechoic zone (HZ), whichwas located below the facet joint (Figure 2). The auxiliary line on the patient’s backskin was drawn at least 9-13 cm away from the midline. Third, the probe was movedto the next highest level to locate the L3-4 intervertebral disc using the same method.One spinal surgeon with more than 5 years of experience in PELD performed thepuncture and cannulation under the guidance of US (Figure 3). The HZ, which waslocated below the facet joint, was used as the target, and the needle was inserted fromthe 12 o’clock position to the 3 o’clock position of the HZ. The tip of the 18-gaugespinal needle first touched the facet joint and then slipped into the intervertebralforamen. G-arm X-ray (Whale, Massachusetts, United States) in the anteroposteriorand lateral views was used to confirm that the needle tip arrived at the target point. Aspecial instrument set (transforaminal endoscopic surgical system; joimax ® GmbH,102 Karlsruhe, Germany) was applied in the procedure. The guidewire was insertedthrough the spinal needle, which was removed thereafter. Then, the obturator andreamer were introduced along the guidewire. Finally, the expanders and outer sheathof the endoscope were inserted through the guidewire one after another (Figure 4).The US-guided puncture lasted 4.5 min (2 min for L3-4 and 2.5 min for L4-5), andthe US-guided cannulation lasted 5.5 min (2.5 min for L3-4 and 3 min for L4-5). Thepositions of the puncture needles and working sheaths were accurate, which wastested by two shots of G-arm fluoroscopy, with a total fluoroscopic time of 4.4 s and atotal radiation dose of 3.98 mGy. Partial hypertrophied facetectomy was performedusing a 3.0-mm endoscopic lateral bur (drill diameter: 3.0 mm, XISHAN, China)(Figure 5). Then, transforaminal PELD was performed as previously described byWen et al [5].OUTCOME AND FOLLOW-UPZhang MB et al. Ultrasound-assisted endoscopic lumbar discectomyFigure 2 Transverse ultrasound image of the lumbar spine. SP: Spinous process; FJ: Facet joint; HZ:Hyperechoic area.The operation decompression lasted 82 minutes for two levels (Figure 5B -D), and itwas completed with no complications. The patient's straight leg elevation increasedfrom 40 to 90 degrees after PELD (Figure 6). Immediately following PELD, the visualanalog scale (VAS) score of his low back pain decreased from 6 to 1, his leg pain scoredecreased from 8 to 1, and his Oswestry Disability Index (ODI) score decreased from73 to 11. Videos of the patient’s gait immediately after surgery showed a normal andsymmetric appearance of the two legs, and the spinal MRI after PELD showedcomplete decompression of the two levels (Figure 7). The patient was taught a set ofwaist exercises after the operation to reduce the recurrence of disc herniation afterPELD. Follow-up at 6 months after PLED showed that the treatment effect remainedthe same without recurrence, with the patient showing 90 degrees of straight legelevation, a VAS of 1 for both low back pain and leg pain, and an ODI of 10. The pati-ent was very satisfied with the treatment, especially with the reduction of radiation.DISCUSSIONRepeated fluoroscopic scanning is essential for the puncture and cannulation duringPELD. Fan et al [6] showed that 34.32±4.78 fluoroscopy shots were needed inconventional PELD. They showed that this number was 33.98 ± 2.69 in another groupof patients [7]. Patients with more difficult positioning and more treatment levels mayreceive larger radiation dose, and the same effect will occur in inexperiencedsurgeons. Fluoroscopic scanning may increase the incidence of malignant tumors,such as thyroid cancer, skin erythema, leukemia and so on [8]. For pregnant women,exposure to X-ray radiation may increase the risk for fetal malformations ordevelopmental abnormalities. High cumulative effective doses also have been foundin patients with Crohn’s disease [9], cystic fibrosis [10], and end-stage kidney disease [11].With the guidance of US, the patient in this study received only two shots offluoroscopy with a low radiation dose of only 3.98 mGy. Future studies with largersamples are needed to validate this technique as an alternative to fluoroscopy.US has been reported to display intervertebral disc degeneration [12,13] and focalstenosis [14]. It has been used in the guidance of facet joint injections [15], selective nerveroot blocks [16], lumbar transforaminal injections [17] and so on. However, due toocclusion of the lumbar spine, displaying the intervertebral foramen remainschallenging. Recently, real-time US-MRI or US-CT fusion image virtual navigation hasbeen demonstrated to be an effective and precise method for guiding PELD [18,19] orlocating an intraspinal tumor [20]. However, the navigation process performed duringthese procedures is complicated and requires a special navigation system, such aselectromagnetic tracking system, which is not easily available.Few studies have focused on US-guided PELD. Wu et al [21] reported an initial studyof US-assisted PELD and suggested that US-guided PELD can be successfullyperformed for patients with a BMI less than 24. In this study, we successfullyperformed US-guided PELD for disc herniation at two levels in a patient with a BMIof 24.6, which suggests that BMI is not always a problem for US guidance. The USguidance method used in our study is different from that used in the above research.They used the facet joint as target and we used the circular HZ above the transverseprocess, which is located below the facet joint, as the target. Furthermore, the needlewas inserted from the 12 o’clock position to 3 o’clock position of the HZ in our study,and no longitudinal scanning was required in our method. The success of the studyZhang MB et al. Ultrasound-assisted endoscopic lumbar discectomyFigure 3 Puncture process of the two spinal needles. A: Ultrasound (US)-guided insertion of the two needles; B: Guidewires were then inserted through the two needles; C: US image of one needle (black arrow indicates the tip of the needle; white arrow indicates the track of the needle); D: Position of the needles in the anteroposterior X-ray image; E: Position of the needles in the lateral X-ray image.proves that, although US cannot penetrate bone, soft tissue or bone markers on UScan be used as guides to assist the puncture.US guidance can not only reduce the radiation dose but also provide real-timedynamic guidance of the needle tip. It can reduce the risk for damage to abdominaland retroperitoneal organs, especially in high level disc herniation. The sheathposition can also be monitored during cannulation, advising the surgeon when to beforceful and when to be careful.Disc herniation of two levels requires double puncture time, longer surgical time,and higher radiation dose administered to the patient. However, with the guidance ofUS, punctures at two levels can be performed at the same time with only two shots offluoroscopy (fluoroscopic time of 4.4 s and radiation dose of 3.98 mGy). The operationdecompression time in our study lasted only 82 min, which is much more likely to beaccepted by patients. The success of this case provides a potential for application ofthis technology. The inclusive and exclusive criteria are meaningful in the process.The inclusion criteria could be radicular leg pain caused by soft LDH with invalidconservative treatment. The exclusion criteria, except for the inherent contrain-dications of PELD, may include obese patients or patients with hyperechoic fasciamuscularis, muscular atrophy, or calcification, since the high attenuation of US makes the anatomical landmarks surrounding the lumbar vertebrae visually unclear.CONCLUSIONThis study is a useful initial attempt and proves that US can be used in the guidanceof the puncture and cannulation of PELD, and can largely reduce the radiation dose.The wide popularization of this technique still needs large samples and controlledstudy. However, with more orthopedists and US physicians mastering spine US andwith the additional development of more practical tools, such as punctured guiding stents, this technology will become more mature and thus has great potential.Zhang MB et al.
