Recanalization of the Portal Vein with a six Years’ Occlusion after Orthotopic Liver Transplantation with Cavoportal Hemitranspostion: A Case Report

Abstract

We report herein a case with recanalization of the portal vein after the complete occlusion in an orthotopic liver transplantation (OLT) with cavoportal hemitransposition six years ago. The patient suffered from end-stage post-hepatitis C cirrhosis with diffused portomesenteric vein thrombosis (PVT), so the caval inflow to the graft was used as a salvage approach in this case. One month after OLT with cavoportal hemitranspostion, the cavoportal anastomosis stoma and the inferior vena cava were occluded by the extensive thrombosis, the inferior vena cava developed recanalization with partial collateral circulation after thrombolysis therapy, but the cavoportal anastomosis stoma blockage lasted six years until 1 month ago the patient’s abdominal enhanced CT indicated blood flow stream in the left and right branch of portal vein (Figure C). This case gives us confidence to practice the cavoportal hemitranspostion and handle the thrombosis of the anastomotic stoma.
