ABSTRACT The inclusion of donor middle hepatic vein (MHV) in right-lobe living-donor grafts and the need for reconstruction of the MHV tributaries have long been controversial areas in living-donor liver transplantation. We report technical details in restoration of venous drainage of the anterior sector (segments V and VIII) of the right lobe of the liver graft using a preserved MHV from the recipient liver, and address the issue of reconstruction of donor MHV tributaries without use of an interposition graft. We review clinical situations in which restoration of outflow drainage of the anterior segment of the liver graft should be considered.

    ABSTRACT: Controversy exists regarding the best method for venous outflow reconstruction after live donor liver transplantation using right lobe grafts. Some authors advocate routine inclusion of the middle hepatic vein with the graft, whereas others favor a more selective approach. In this report, we examine the evolution of our decision making and technique of selective anterior venous segment reconstruction during live donor adult liver transplantation performed in 226 recipients. We have developed a simplified back-bench procedure using sequential-composite anastomosis using various vascular conduits with syndactylization to the right hepatic vein creating a single large-outflow anastomosis in the recipient. Conduits used include iliac artery or vein allograft, recanalized umbilical vein, cryopreserved iliac artery allograft, and 6-mm synthetic expanded polytetrafluoroethylene vascular graft. This technique can be performed quickly, safely, and under cold storage conditions and results in excellent outcome while minimizing donor risk.
