Massive Gastrointestinal Hemorrhage Due to an Arterioenteric Fistula From a Hepatic Artery Pseudoaneurysm

Hepatic artery pseudoaneurysms are a rare cause of upper gastrointestinal bleeding with a high mortality rate. We report a case of a 37-year-old woman who presented with massive gastrointestinal hemorrhage and was found to have an arterioenteric fistula from a hepatic artery pseudoaneurysm. Esophagogastroduodenoscopy revealed a 1.5-cm ulcer overlying a large mucosal bulge that compressed the lumen of the duodenal bulb. A vascular stent graft was placed successfully over the pseudoaneurysm neck. We report the first case of the unique intraluminal appearance of an enteric fistula related to a hepatic artery pseudoaneurysm.
