[Sonographic diagnosis of amniotic band syndrome].

A case is reported of sonographic diagnosis of ADAM-complex (amniotic band syndrome) in the 19th week of gestation of an otherwise healthy pregnancy. The ultrasonic investigation showed absence of bony structures in the skull area a direct connection to the placenta. The intra-cerebral structures showed no abnormalities. Aminocentesis demonstrated normal chromosomal analysis and an alpha-fetoprotein value was within normal limits. The acetylcholinesterase examination was negative. Following prostaglandin induction, a spontaneous delivery of a 230 g freshly dead fetus occurred, the latter exhibiting a broadly-based amniotic band connection between skull and placenta.
