Constriction of the umbilical cord by an amniotic band, with fetal compromise illustrated by reverse diastolic flow in the umbilical artery. A case report.
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.
