Late third trimester ultrasound diagnosis of duodenal atresia - the importance of detailed prenatal ultrasound screening

J.A. Akinmoladun, T.A. Lawal, A Hafiz


Duodenal atresia (DA) is the commonest type of congenital small bowel obstruction usually presenting in the neonatal period. About half of fetuses with duodenal atresia have other associated anomalies, and these associations often contribute to morbidity and mortality. DA can be fatal unless promptly diagnosed and treated surgically. In experienced hands and in countries where prenatal ultrasound screening for anomalies is routine, DA can be confidently diagnosed prenatally, which can help in reducing the perinatal morbidity and mortality associated with diagnosis after delivery.

We report a case of DA diagnosed by ultrasonography at 36 weeks gestation in a 34 year old multiparous woman in a hospital where targeted prenatal ultrasound screening for fetal anomalies was recently introduced, and reviewed relevant literature
