[Mesenteric ischemia in hemodialysis patients: case report and review of the literature].

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.
