Spontaneous resolution of amniotic bands.
The amniotic band syndrome comprises a group of sporadic congenital anomalies characterized by amputations, constriction bands, pseudosyndactylism and multiple craniofacial, visceral and body wall defects. It occurs in approximately 1 in 1200 to 1 in 15 000 live births. Some of the cases present with congenital anomalies that are incompatible with life, but a selected group shows isolated limb constrictions. Repeated sonographic examinations afforded us the opportunity of observing the in utero process of limb strangulation and subsequent spontaneous lysis of an amniotic band attached to a fetal elbow. Surgical fetal therapy with lysis of the constriction ring in utero is an option, but intervention is probably not always warranted. Spontaneous resolution does occur.
