Abstract

Hepatic artery aneurysms (HAA) are rare and life-threatening. We report a case of a 68-year-old man with a huge HAA diagnosed incidentally. Computed tomography showed a huge HAA (67-84 mm diameter). The patient underwent aneurysm resection and ligation of the common and proper hepatic arteries via laparotomy. Revascularization was not performed because intraoperative ultrasound showed pulsatile inflow to the left hepatic lobe. Postoperative cholecystitis and hepatic infarction were temporarily observed. Two months after the previous discharge, cholecystectomy was performed. A diameter ≥5 cm of HAA is thought to be rare in arterial aneurysm diseases. There is no consensus in the treatment policy and treatment is selected according to the patient's condition. In this case, we selected open surgery for this patient instead of endovascular surgery due to rupture risks, irregularity and narrowness of vessel structure, and prolonged irradiation-time. If revascularization is not performed at the time of resection, open surgery with cholecystectomy is capable of preventing postoperative cholangitis after resection of HAA, and should be taken into account even if collateral circulation can be confirmed. This case highlights the difficul...Continue Reading
