title: Prenatal demonstration of gastric and duodenal obstruction by ultrasound.
abstract: Prenatal sonographic findings in one case of gastric obstruction due to an imperforate antral diaphragm and in one case of duodenal atresia are presented. The combination of either one or two prominent sonolucent areas in the upper or mid fetal abdomen and polyhydramnios is virtuallydiagnostic of high obstruction.
