Superior mesentric artery compression syndrome.

ABSTRACT

Superior Mesenteric Artery Syndrome is an atypical cause of high intestinal obstruction seen frequently in patients with rapid weight loss or immobilization in a body cast (\also called CAST Syndrome). The SMA impinges on the third part of the duodenum immediately after originating from the anterior aspect of aorta, making an abnormally narrow angle with the later. Intestinal obstruction results causing characteristic symptoms like postprandial epigastric pain, eructations, fullness and vomiting. Here we report such a case of SMA syndrome in a patient with history of rapid loss of weight.
