Constriction of the umbilical cord by an amniotic band is a rare entity, associated with a high rate of fetal mortality and congenital anomalies. A case occurred with early detection and successful intervention for fetal compromise caused by the amniotic band, which was associated with first-trimester amniocentesis. This is the first known report of ultrasound Doppler flow studies in a case of umbilical cord constriction by an amniotic band, showing reverse diastolic flow in the umbilical arteries.
羊膜带对脐带的压迫是一种罕见情况，与胎儿高死亡率和先天性畸形相关。有一例早期检测到羊膜带导致胎儿窘迫并成功干预的病例，该病例与孕早期羊膜腔穿刺术有关。这是已知的首例关于羊膜带压迫脐带病例的超声多普勒血流研究报告，显示脐动脉舒张期血流反向。
