Celiac artery aneurysm is very uncommon. We report an even more rare case in which a life threatening ruptured aneurysm was treated successfully by an emergency interventional procedure. A 72-year-old man was transferred to our hospital with a chief complaint of severe epigastralgia. In the emergency room, the patient was already in shock and emergency CT scan suggested severe intraperitoneal bleeding. The diagnosis of ruptured celiac artery aneurysm was confirmed by subsequent angiographic examinations and immediate hemostasis was successfully achieved by transcatheter arterial embolization. One year after the embolization, the patient remains asymptomatic and follow-up CT scans revealed reduction in size and thrombotic occlusion of the aneurysm.
