Ileal atresia associated with a congenital vascular band anomaly: observations on pathogenesis.

We report the case of a newborn, who developed intestinal obstruction soon after birth. Exploratory laparotomy revealed a congenital vascular band anomaly extending from the antimesenteric border of the terminal ileum to the gallbladder in association with ileal atresia. Surgical intervention was performed for correction of the disorder. A review of the embryology and congenital vascular bands is presented together with discussion as to possible etiopathogenesis leading to small bowel atresia.
