title: Successful covering of a hepatic artery aneurysm with a coronary stent graft.
abstract: In a 54-year-old woman with liver cirrhosis who underwent orthotopic liver transplantation, the postoperative course was complicated by aneurysm formation in the hepatic artery. Abdominal ultrasonography showed a daily increase in size of the aneurysm in spite of careful management including strict rest and continuous intravenous infusion of antihypertensive agents. Since the patient's poor systemic status was a major obstruction to operative resection, transcatheter therapy was though more preferable. We evaluated the lesion with intravascular ultrasonography as an adjunct to angiography and dissection with a flap was well visualized. The aneurysm was covered with a commercially available stent-graft, designed for treatment of the coronary artery. This is a rare case in which a Jostent was implanted into the hepatic artery after liver transplantation.
