A case of acute superior mesenteric arterial occlusion with successful emergency simultaneous side-to-end anastomosis.

A 72-year-old woman was transferred to our critical care center because of transient loss of consciousness and aphasia. She had a history of abdominal pain, nausea, and atrial fibrillation, and reported on admission mild abdominal rebound tenderness, inflammatory response, acidosis and renal dysfunction. We suspected acute superior mesenteric arterial occlusion (SMAO) after cerebral infarction. We performed simultaneous reconstruction with side-to-end anastomosis using circular and linear staplers, rather than jejunostomy, which avoided the loss of massive intestinal contents and frequent diarrhea. A detailed history is important to make a diagnosis of acute SMAO and simultaneous reconstruction with side-to-end anastomosis is an important treatment option.
