Superior mesenteric artery (SMA) syndrome is a relatively rare aetiology of proximal intestinal obstruction. This is caused by narrowing of vascular angle of SMA and aorta compressing the third part of the duodenum (D3). Predisposing factors may include precipitous weight loss, corrective spinal surgery or repair of an aortic aneurysm.
