Endovascular Management of Thrombosed Cavoportal Anastomosis After Liver Transplantation Using Catheter Directed Thrombolysis and Stent Placement: A Case Report.

Cavoportal hemitransposition (CPHT) is a rarely performed treatment technique in liver transplantation in cases of extensive splanchnic thrombosis, in which the inferior vena cava of the recipient is used to perfuse the portal vein of the allograft. A case of a 65-year-old liver transplantation patient with an acutely thrombosed cavoportal anastomosis is presented. After unsuccessful medical treatment, recanalization was obtained with transfemoral catheter directed thrombolysis, angioplasty and stent placement. Although this type of treatment has been extensively documented for the management of portal anastomotic problems after orthotopic liver transplantation, data on its application in modified transplantation techniques including CPHT are rare. This technique provides a minimally invasive treatment option in CPHT patients with cavoportal anastomotic problems, who might otherwise require complex surgical repair or retransplantation.
