Presentation of aortic dissection (AD) typically includes chest and/or abdominal pain. Gastrointestinal (GI) symptoms other than abdominal pain are uncommon. Two patients with AD are described in whom the dominant presenting symptom was GI hemorrhage. Mesenteric infarction complicated acute Type I dissection in one patient whose clinical manifestations simulated ulcerative colitis. In the other patient an old, small asymptomatic Type III AD resulted in a false aneurysm in the retroperitoneum which ruptured into the duodenum. In the latter case an antemortem diagnosis was not made as angiography was limited to the visceral arteries and the abdominal aorta without appreciation of the significance of a focal compression of the abdominal aorta. The possibility of AD thus should also be considered in the evaluation of a patient with acute GI bleeding.

Mesenteric infarction is increasingly observed in uremic elderly patients with widespread atherosclerosis. A 77-year-old man on renal replacement therapy since June 1997 was admitted because of abdominal pain. The surgical diagnosis was massive intestinal infarction and the patient died a few hours later. A colonoscopy had been performed a few weeks before and a well-limited necrosis of the caecum mucosa had been detected. Hypotensive episodes were frequent during his hemodialysis sessions. In this work we discuss age, symptoms, laboratory investigations, risk factors and the evolution of case reports published during the last few years. Nephrologists should take into account the possibility of mesenteric ischemia in uremic patients with manifest arterio-occlusive disease, abdominal pain and leukocytosis, especially if hypotension is the major complication of the hemodialysis sessions.
