[摘要] 目的 分析胡桃夹综合征患者左肾静脉超声影像特征和规律及其诊断意义。 方法选择2016年5月～2018年4月在我院接受诊断的胡桃夹患者150例作为观察组，选择同期体检健康志愿者150例作为

对照组，两组受检者均接受超声检查其左肾静脉，分析超声影像特征和规律及其诊断意义。 结果 观察组经

超声检查发现其左肾静脉近心端及远心端内径，近心端及远心端血液流速在站立位、平卧位、双腿蹲位及单

膝屈曲卧位时，两两比较，数据差异均有统计学意义（P＜0.05）；观察组AO与SMA夹角、左肾静脉最窄段

内径、左肾静脉最窄段与最宽段内径比值均显著小于对照组，差异有统计学意义（P＜0.05）。 结论 胡桃夹

综合征患者左肾静脉近端及远端管腔内径、血液流速在不同体位时数据存在一定的差异，而且其左肾静脉

最窄段内径、SMA与AO夹角均低于健康人。

[Abstract] Objective To analyze the ultrasonic image features and regularity of left renal veins in patients with nutcracker syndrome and its diagnostic significance. Methods 150 patients with nutcracker syndrome who were diagnosed in our hospital from May 2016 to April 2018 were selected as the observation group.150 healthy volunteers who underwent physical examinations during the same period were selected as the control group.Ultrasound examination

of the left renal vein was performed in both groups,and the characteristics and regularity of the ultrasound image and its diagnostic significance were analyzed. Results Ultrasound examination showed that the diameter and blood flow velocity

of the proximal and distal end of the left renal vein was statistically significant different in the standing position,supine position,two-leg kneeling-squatting position and one-knee flexion position(P＜0.05).In the observation group,the angle between AO and SMA,the inner diameter of the narrowest segment of left renal vein and the ratio of inner diameter of the narrowest segment to the widest segment of left renal vein were all significantly smaller than those in the control group.

The differences were statistically significant (P＜0.05). Conclusion The internal diameter and blood flow velocity of the proximal and distal renal veins of patients with nutcracker syndrome are different in different positions.The inner diameter

of the narrowest segment of the left renal vein and the angle between SMA and AO are lower than those of healthy people.

胡桃夹综合征，是因其左肾静脉因受到腹主动脉、肠系膜上动脉挤压而形成的临床综合征，其病变原因可分为先天或后天，主要临床特征包括血尿、直立性蛋白尿等，对患者正常工作、生活可造成不同程度的干扰，使其生活质量下降[1-2]。胡桃夹综合征影像学诊断主要包括血管造影、CT[3]及MRI 等，其中因血管造影属于有创检查，CT及MRI检查成本较高，而且CT属于放射性检查，因此多以无创、图像清晰、性价比较好的超声作为首选检查措施[4-5]。本次研究选择2016年5月～2018年4月在我院接受诊断的胡桃夹患者150例作为观察组，选择同期体检健康志愿者150例作为对照组，两组受检者均接受超声检查其左肾静脉，分析超声影像特征和规律及其诊断意义，获得一定研究成果，现
