Arteriomesenteric syndrome as a cause of duodenal obstruction in children with cerebral palsy.

Two cases of gastroduodenal outlet obstruction caused by arteriomesenteric compression in children who have cerebral palsy are reported. Clinical symptoms of gastrointestinal obstruction include recurrent postprandial nausea and vomiting, upper abdominal distension, and pain. In such patients, multiple predisposing factors can contribute to the development of arteriomesenteric compression, including marked weight loss, supine position, and severe scoliosis. Upper gastrointestinal x-rays using barium contrast allow diagnostic confirmation. In our experience, this cause of acute gastroduodenal outlet obstruction may usually resolve after conservative treatment using a jejunal feeding tube passed beyond the compression, left lateral positioning, and renutrition.
