Portal hypertension resulting from mesenteric arterioportal fistula: Treatment by transcatheter embolization

Arterioportal fistulae are a relatively uncommon cause of portal hypertension. Surgical treatment of these lesions can be associated with significant morbidity. Transcatheter embolization is an effective means of treatment which carries a very low morbidity and mortality rate. We present a case of transcatheter embolization of a presumed post-traumatic superior mesenteric artery-superior mesenteric vein fistula in a patient who presented with signs and symptoms of severe portal hypertension.
