We experienced a rare case of hepatic artery aneurysm as a complication of microwave coagulation therapy. The patient was 79 years old man with gastric carcinoma and hepatocellular carcinoma. Hepatic tumors were located in S5 and S8. Totalgastrectomy and Microwave coagulation therapy (MCT) for hepatic tumor were performed simultaneously. On the 9th P, O, D and 19th P, O, D massive bleeding occurred with attendant hypovolemic shock. On the first episode, patient recovered by conservative therapy with blood transfusion. However, the emergency angiography carried out and revealed hepatic artery aneurysm, which ruptured into the abdominal cavity on the 19th P, O, D. Hemostasis was accomplished by transcatheter arterial embolization (TAE). Although, MCT is a effective treatment for hepatic tumor, the hepatic aneurysm is to be one of fatal complication.
