[Early amnion rupture or amniotic band syndrome]

Abstract

Early rupture of the amnion with resultant oligohydramnios and subsequent development of mesodermal bands between the chorion and the fetus can cause various deformities. The degree of deformity depending on the extent of the band formation and the gestational age at which this occurs. The condition may involve all parts of the fetus and comprizes a spectrum ranging from clinically insignificant small constricting bands on the extremities to large craniofacial and visceral defects which may be fatal and cause abortion. Prenatal diagnosis relies mainly on ultrasonic investigation, and the treatment--quo ad vitam--consists mainly of reconstructive surgery. A case is reported.
