MR of superior mesenteric arteryrenal vein fistula

Abstract

Traumatic arteriovcnous fistulas involving the superior mesenteric artery are rare. Diagnosis is most commonly made shortly after the injury. Symptoms, when present, are usually related to intestinal ischemia. Angiography has been the conventional modality used in diagnosing arteriovcnous fistulas. We report a patient with a superior mesenteric artery to left renal vein fistula who presented in overt heart failure five years after a gun shot wound. The fistula was evaluated with magnetic resonance imaging.
