Embolization of a duodenal arteriovenous malformation in hereditary hemorrhagic telangiectasia: case report and review of the literature.
A 68-year-old man with hereditary hemorrhagic telangiectasia presented with recurrent, intermittent gastrointestinal hemorrhage. Transfusion of a total of 27 units of red blood cells was required over the three months before admission. Upper and lower endoscopy did not reveal a source of bleeding and a technetium-labelled red blood cell scan was noncontributory. Angiography demonstrated a duodenal arteriovenous malformation originating from a superior mesenteric artery branch. Embolization of the arteriovenous malformation was performed with resolution of gastrointestinal hemorrhage and reduced requirement for blood transfusion. The utility of trans-catheter embolization in the management of duodenal arteriovenous malformations in hereditary hemorrhagic telangiectasia is discussed.
