Prenatal sonography of extracorporeal ductus venosus in association with large fetal gastroschisis.
Liver herniation commonly associated with omphalocele occurs in only approximately 2.3% to 16% of fetuses with gastroschisis. Liver herniation in such cases is associated with considerably decreased survival rates (43% vs 97% with or without liver herniation, respectively). Rarely, abnormally positioned fetal hepatic vasculature has been reported mainly in association with congenital diaphragmatic hernia. In these rare cases, intrathoracic depiction of hepatic venous vasculature has assisted in confirming intrathoracic displacement of the fetal liver. We present a case of a large gastroschisis with complete herniation of the fetal liver in which prenatal sonography depicted an extracorporeal ductus venosus.
