Current management of mesenteric extrahepatic arterioportal fistulas: report of a case treated with a gastroduodenal artery stent graft and literature review

Abstract

Spontaneous arteriovenous fistulation of a pseudoaneurysm into superior mesenteric vein (SMV) has rarely been reported. We present the case of a 61-year-old woman who presented with a post pancreatic arterioportal fistula (APF) that was successfully managed by stent graft (SG) placement in the gastroduodenal artery (GDA). We also review the published experience of the endovascular management of mesenteric extrahepatic APFs. This review demonstrates the evolution from open surgical to endovascular management for majority of these patients.
