Abstract

Superior mesenteric artery (SMA) syndrome results from compression of the third portion of the duodenum by the superior mesenteric artery or one of its branches where this vessel crosses over the duodenum as it descends from the aorta. Recently 2 cases of SMA syndrome were experienced. A 43-year-old female and a 41-year-old male were admitted due to complaints of frequent postprandial abdominal distension and vomiting for 4 months. An UGI series and abdominal CT scan revealed distension of stomach and duodenum with a cut-off in the duodenal third portion. Both patients underwent duodenojejunostomy with successful symptom relief. (Korean J Gastrointest Endosc 19: 823∼828, 1999)
