Fetal hydrops associated with spontaneous premature closure of ductus arteriosus.
A 36-year-old woman presenting with fetal growth restriction in the 25th week of gestation was referred to Kobe University Hospital where hydrops fetalis was detected. A stillborn fetus, 2012 g in weight and 40 cm in height, was delivered in the 33rd week of gestation. The mother had no past history of non-steroidal anti-inflammatory drug (NSAID) use during the pregnancy. The male fetus showed maceration without macroscopic anomalies, but it was markedly edematous with bilateral pleural effusion and massive ascites. The autopsy revealed an enlarged heart and aortic coarctation in the region of the ductus arteriosus. A mild form of aortic coarctation and premature closure of the ductus arteriosus with fibrous thickening of the wall were observed. The lungs were atelectatic with vascular dilatation and congestion. This is the first documented case of hydrops fetalis caused by spontaneous premature closure of the ductus arteriosus concomitant with aortic coarctation. The findings suggest that some form of idiopathic, or spontaneous, closure of the ductus arteriosus can be one of the causes of chronic fetal heart failure, coarctation of the aorta, and fetal hydrops.
