Superior mesenteric arteriovenous fistula presenting as gastrointestinal bleeding: case report and literature review.
Superior mesenteric arteriovenous fistula (SMAVF) is a rare vascular disorder usually following penetrating abdominal trauma or gastrointestinal surgery. Percutaneous endovascular treatment such as embolization, has been widely used to treat this disease. We report a patient, who was presented with melena at the onset of his symptoms, then an acute hematemesis in shock. A SMAVF was diagnosed on an angiogram after a large mesenteric vein was seen on CT. The patient had a successful emergency endoscopic variceal ligation (EVL) to stop bleeding. Then the patient received fistula embolization with covered stent.
