A Case of Congenital Duodenal Atresia Diagnosed by Prenatal Ultrasonography

Abstract
|
|
|
|
Duodenal atresia is amenable to prenatal ultrasonographic diagnosis in the majority of cases. Such diagnosis is based on visualization of the "double-bubble" sign, which represents the simultaneous distension of the stomach and duodenum. Most cases of duodenal atresia are first diagnosed in the third trimester of pregnancy, and some reports suggest that the diagnosis may not be possible before the third trimester. We present a case of congenital duonenal atresia diagnosed by ultrasonography at 34 weeks gestational age.
