Superior mesenteric artery syndrome following abdominal aortic aneurysm resection and replacement.

The case is reported of a 75-year-old female patient developing, on the 15th day after partial resection of an abdominal aortic aneurysm and replacement with vascular prosthesis, acute syndrome of aortomesenteric occlusion of the duodenum. The condition was caused by postoperative haemorrhage into the space framed by the aortic prosthetic replacement and its wrapping with the remnants of the aneurysmal sac. Acute ileus arising subsequently was controlled by posterior gastroenterostomy and Braun's entero-enterostomy between the afferent and efferent loops.
