Ruptured superior mesenteric artery aneurysm due to fibromuscular dysplasia. A rare vascular presentation in a patient with schizophrenia
Visceral aneurysms are rare entities, with a reported incidence of 0.01-2%. Fibromuscular dysplasia is a non-atherosclerotic, non-inflammatory artery disease which may predispose to aneurysmal degeneration. Schizophrenia has been linked to an increased cardiovascular risk because of the influence of traditional and disease specific risk factors. We report the case of a 44-year old male schizophrenic patient presenting with a ruptured giant aneurysm of superior mesenteric artery, managed by mesenteric ligation. The histologic diagnosis was fibromuscular dysplasia.
