title: Cast syndrome: the superior mesenteric artery syndrome.
abstract: Cast syndrome, clinically known as superior mesenteric artery syndrome (SMAS), is gastric dilatation with partial or complete obstruction of the duodenum. Although rare, it is most frequently seen in orthopaedic patients who have had spinal surgery or who are in hip spica or body casts. Obstruction occurs when there is compression of the duodenum between the superior mesenteric artery anteriorly and the aorta and spinal column posteriorly. Obstruction can occur within days of surgery or casting or may not develop for several weeks. Treatment for SMAS varies from conservative nonoperative to operative procedures. Complications can be severe if symptoms are not quickly recognized and treatment instituted in a timely manner.
