title: Open and endovascular repair of hepatic artery aneurysm: two case reports and review of the literature.
abstract: Hepatic artery aneurysms (HAAs) represent a complex and often lethal condition. An 80-year-old woman with polyarteritis nodosa and a right hepatic lobe HAA underwent endovascular repair with coils. Her case was complicated by intraoperative HAA rupture requiring exploratory laparotomy. In the second case, a 37-year-old man with a large HAA underwent open repair with a bifurcated graft that extended from the common hepatic artery to the left and right hepatic arteries. These two cases highlight the difficulty of managing HAAs, and provide insight into their treatment. Furthermore, our review of the literature highlights the data on the management of HAAs, including the natural history of this disease process, the indications for repair and the optimal treatment modality.
