Abstract

A pancreatic arteriovenous malformation (AVM) is a very rare disease entity that is usually asymptomatic; however, it may present with a massive gastrointestinal hemorrhage. Recent advances in cross-sectional imaging and the widespread availability of angiography have contributed to the diagnosis of this condition. A patient was transferred to our clinic due to unknown origin gastrointestinal bleeding and upper abdominal pain. Double balloon enteroscopy and duodenoscopy revealed a bleeding pancreatico-cholangio-duodenal fistula. We were able to diagnose an arteriovnous malformation with a pancreatico- cholangio-duodenal fistula by the use of angiography and from the post-operative pathological findings.
