During 8～12 weeks：with firm
attachment to the basal decidua ➢ Partial expulsion of the products of
conception→ non-ideal uterine contraction, severe bleeding
➢ Early Abortion：pregnancy loss before 12 gestational weeks
➢ Late Abortion: pregnancy loss during 12～28 gestational weeks
➢ Spontaneous Abortion ➢ Artificial Abortion
After 12 weeks: placenta fully formed.
➢ Uterine contraction→ expulsion of all the products of conception，light bleeding
Symptoms
Amenorrhea, vaginal bleeding , and abdominal pain
Dilated
Normal or slightly small
Incomplete Light to Abortion heavy
Relieved
Partial
Dilated or Small obstructed
Complete Light to none None Abortion
inevitable abortion
incomplete abortion
complete abortion
Diagnosis
History
Physical Examination
Laboratory Assessment:
➢ ultrasound ➢ pregnancy test ➢ hormone level: serum progesterone
➢ Missed Abortion ➢ Habitual Abortion ➢ Septic Abortion
Clinical Presentations
Threatened Abortion ➢ light vaginal bleeding with mild abdominal
pain ➢ cervical os closed, fetal membranes unbroken ➢ treatment might work , continue pregnancy
➢ Early abortion：vaginal bleeding preceding abdominal pain
➢ Late abortion：abdominal pain preceding vaginal bleeding
Types of Abortion
Threatened Abortion Inevitable Abortion Incomplete Abortion Complete Abortion
Pathology
Before 8 weeks: chorionic villi immature
➢ Fetal death→basal decidual bleeding →uterine contraction→expulsion of all the products of conception, light bleeding
abdominal pain alleviating ➢ cervical os closed ➢ uterus normal for the
presumed gestational week
Different Stages of Abortion
threatened abortion continue pregnancy
Incomplete Abortion ➢ heavy vaginal bLeabharlann Baidueeding ➢ pregnancy tissue protruding
from the cervical os ➢ uterus small for the presumed
gestational week
Complete Abortion ➢ vaginal bleeding decreasing,
Inevitable Abortion ➢ bleeding heavier, abdominal pain more
severe, or fluid passed ➢ cervical os open，pregnancy tissue visible ➢ abortion is inevitable
