Duodenal atresia with 'apple-peel configuration' of the ileum and absent superior mesenteric artery: a rare presentation.

According to the current understanding, duodenal atresia is considered to be a primary malformation resulting from the errors in recanalisation in early gestation. We report a rare case of duodenal atresia with apple-peel configuration of remaining small bowel with absent superior mesenteric artery in a preterm child, which indicates that in rare circumstances vascular accidents may be the underlying cause for duodenal atresia, and jejuno-ileal atresia; only second such case to be reported in the English literature.
