Superior Mesenteric Artery Syndrome Following Augmentation Cystoplasty

Abstract

Superior mesenteric artery syndrome (SMAS) is a rare condition of external duodenal compression in the angle between the superior mesenteric artery and aorta. We report a case of SMAS following augmentation cystoplasty in a young patient.

Superior mesenteric artery syndrome (SMAS) is a rare condition that usually presents with symptoms of upper gastrointestinal (GI) obstruction due to extrinsic compression of the third part of duodenum between the abdominal aorta posteriorly and superior mesenteric artery (SMA) anteriorly. Several predisposing factors have been described, however; severe weight loss is considered the most significant. Reduction in the angle and distance between the aorta and the SMA causes compression of the duodenum. Conservative treatment plays a major role in such cases; however, failure of such measures may warrant surgical intervention.
