Pseudoaneurysms of the hepatic artery are a rare complication of liver transplantation. Early diagnosis and treatment are essential to avoid life-threatening hemorrhage. Conventional treatment consists of surgical resection and vascular reconstruction or transarterial coil embolization. More recently, percutaneous thrombin injection has been successfully used in the treatment of femoral artery pseudoaneurysms. We describe a 70-year-old woman who had a hepatic artery pseudoaneurysm after orthotopic liver transplantation, which was successfully treated by percutaneous thrombin injection.
