  • Title: Superselective arterial embolization in the liver transplant recipient: a safe treatment for hemobilia caused by percutaneous transhepatic biliary drainage.

    Abstract:
    Transcatheter arterial embolization is widely used to treat life-threatening iatrogenic hemobilia, although in the transplanted liver its use has only been reported in two cases. To evaluate more fully whether transcatheter embolization is safe and effective in transplant recipients, we retrospectively reviewed eight cases of severe hemobilia. These occurred after 128 percutaneous transhepatic biliary drainage procedures performed during a 6-year period. In each case, angiography localized the bleeding to a specific intrahepatic branch that was then subselectively catheterized and occluded by transcatheter embolization. Bleeding was successfully controlled by this method in all eight patients with no immediate complications. The main, right, and left hepatic arteries were shown to be patent immediately after embolization by angiography in all patients. Duplex sonography performed in each case (1 to 4 months) after the procedure confirmed that patency was maintained in all patients. No patients developed liver abscesses, sepsis, or clinical liver infarctions after the embolization. No patients underwent retransplantation after embolization. Our experience shows that superselective transcatheter embolization is a safe, effective therapy to correct iatrogenic hemobilia in the liver transplant recipient without threatening the patency of the major hepatic arteries, the viability of the liver, or the integrity of the biliary tree.
