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 entit y, associated with a high rate of fetal mortality and congenital anoma lies. A case occurred with early detection and successful intervention for fetal compromise caused by the amniotic band, which was associate d with first-trimester amniocentesis. This is the first known report o f ultrasound Doppler flow studies in a case of umbilical cord constric tion by an amniotic band, showing reverse diastolic flow in the umbili cal arteries.
