Severe nonimmune hydrops fetalis: sonographic evaluation.

Abstract

Reported survival rates in nonimmune hydrops fetalis vary considerably. Among 27 fetuses exhibiting severe sonographic features of nonimmune hydrops fetalis, 33% survived the neonatal period. For five of the nine survivors, the prognosis remains uncertain or poor. On the basis of sonographic features alone neither prognosis nor potential survivors were reliably predicted.
