Serial transabdominal amnioinfusion in the management of gastroschisis with severe oligohydramnios.

Two fetuses with gastroschisis diagnosed in utero (at 19 weeks' gestation) had severe oligohydramnios at 30 to 31 weeks. Serial transabdominal amnioinfusions were performed to fill the amniotic cavity with saline, thereby avoiding the potential consequences of fetal exposure to severe oligohydramnios. In both cases, premature rupture of membranes occurred at 36 weeks, and the fetuses were delivered by cesarean section. There were minimal lesions of the extraabdominal bowel. After primary closure of the abdomen, the postoperative course was uneventful. These observations show that serial amnioinfusion is a feasible therapeutic approach for severe third-trimester oligohydramnios associated with gastroschisis.
