Superior mesenteric artery syndrome leading to reversible mucosal gangrene.

We describe a case in which gastrointestinal distention due to superior mesenteric artery syndrome (SMAS) developed into membranous gangrene, which in turn led to septic shock in a 60-year-old woman with cerebral palsy and cachexia. The association with SMAS and septic shock is considered extremely rare, it is important to consider this combination especially in cachectic patients with gastric distension accompanying refractory shock unknown etiology.
