Prenatal diagnosis of gastrointestinal tract obstruction

The diagnosis of possible duodenal atresia was made in a near-term fetus. The mother had developed polyhydramnios, and the fetus was found on sonography to have two communicating upper abdominal masses. It also failed to ingest contrast media after injection of radiopaque material into the amniotic sac. An esophageal atresia was found after delivery, in addition to the prenatally diagnosed duodenal atresia. The infant had a surgical repair 16 hours after delivery and survived.
