A 41-year-old man was admitted to our hospital with gastrointestinal bleeding. Esophagogastroduodenoscopy revealed a submucosal protrusion with erosion in the duodenal bulb which was thought to be the bleeding source. Dynamic CT scan, ultrasonography and angiography of the abdomen revealed a hepatic artery aneurysm and a dilated celiac artery that dissected from its origin. Although we considered percutaneous transcatheter arterial embolization with metallic coils, we chose surgical resection and vascular reconstruction to prevent hepatic ischemia resulting from interruption of collateral circulation. On the 8 th day, hepatic artery aneurysmectomy and revascularization with a great saphenous vein was carried out without any severe complication. The pathological specimen demonstrated segmental arterial mediolysis.
