A case report of superior mesenteric artery syndrome

Abstract

Abstract Superior mesenteric artery (SMA) syndrome is a rare condition resulting in small bowel obstruction. The third part of the duodenum becomes compressed because of the narrow angle between the aorta and the SMA. Those at risk of developing SMA syndrome include patients who develop rapid weight loss, malignancy, eating disorders, burns, trauma and substance abuse. We present a case of a 73-year-old man that presented 5 days post a total hip replacement with abdominal pain and profuse bilious vomiting for 2 days. A computed tomography scan of his abdomen showed gross distension of his stomach with an abrupt occlusion of the duodenum at the level of the SMA which was consistent with SMA syndrome. The patient was treated conservatively and was later discharged from surgical services once his symptoms resolved and he was able to tolerate diet.
