A live birth after spontaneous complete chorioamniotic membr
Complete chorioamniotic membrane separation (CMS) occurs extremely rarely without invasive fetal procedure. CMS has been associated with adverse perinatal outcomes. We present the case that CMS occurred spontaneously without invasive fetal procedures or fetal structural abnormality. We infer that the uterine scar detected during Cesarean section was one of the possible reasons for the CMS, and that the uterine muscle defect had been caused by the previous dilatation and curettage before this pregnancy.
Case report
A healthy 35-year-old woman, gravida 3 para 1, was referred to our unit at 21 weeks and 5 days' gestation because of CMS. The course of the pregnancy had been uneventful until 16 weeks with no history of amniocentesis or abdominal trauma. The patient had two previous pregnancies. The first pregnancy had been uneventful, resulting in a caesarean delivery at term. The second pregnancy was terminated by dilatation and curettage because of a missed abortion at 8 weeks' gestation....
