Severe nonimmune hydrops fetalis: sonographic evaluation.

Abstract
Reported survival rates in nonimmune hydrops fetalis vary considerably. Among 27 [human] fetuses exhibiting severe sonographic features of nonimmune hydrops fetalis, 33% survived the neonatal period. For 5 of the 9 survivors, the prognosis remains uncertain or poor. On the basis of sonographic features alone, neither prognosis nor potential survivors were reliably predicted.
