    Abstract:
    Parenchymal pseudoaneurysm of the hepatic arteries with massive intraperitoneal bleeding is rare but a serious life-threatening complication when it occurs following liver transplantation. We report a case of an adult postliving donor liver transplant recipient who developed massive subcapsular bleeding combined with massive right pleural effusion from ruptured multiple small intrahepatic arteries, which developed from a pseudoaneurysm that was treated by hepatic arterial embolization. Successful embolization was performed via a percutaneous trans-catheter approach by depositing 20-25%N-butyl-2-cyanoacrylate (NBCA) through the multiple small intrahepatic arteries into the pseudoaneurysm. Complete occlusion of the feeding arteries and pseudoaneurysm cavity resulted to immediate cessation of bleeding. There was no re-bleeding; and normal liver graft function was noted postembolization. Hepatic arterial embolization with NBCA can be used as treatment for postliver transplant peripheral intrahepatic artery pseudoaneurysm bleeding.
