Superior Mesenteric Artery Syndrome Accompanying With Nutcracker Syndrome: A Case Report

Introduction: Superior mesenteric artery syndrome is an uncommon cause of duodenal obstruction, and its manifestations are generally associated with compression on the third part of the duodenum between the abdominal aorta and superior mesenteric artery. Case Presentation: In this report, a patient is described presenting with epigastric pain and weight loss due to superior mesenteric artery syndrome. The patient has also nutcracker syndrome, which is the compression of the left renal vein between the aorta and the superior mesenteric artery at its origin. Conclusions: In addition to an appropriate clinical history, CT findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome.
