"Single Oval Ostium Technique" using Polytetrafluoroethylene Graft for Outflow Reconstruction in Right Liver Grafts with venous Anomalies in Living Donor Liver Transplantation.

Right lobe living donor liver transplantation form a major source of liver allografts in Asia because of the scarcity of deceased donation. However, the transplant surgeons often face challenges while managing right lobe liver allografts due to variations in vascular anatomy. Such variations have led the transplant team to adopt modifications in existing techniques of inflow and outflow reconstruction. One of such variations is presence of multiple draining inferior right hepatic veins (IRHVs). This hepatic venous anomaly pose a lot of technical difficulties in the outflow reconstruction as second and/or third anastomosis to inferior vena cava is not always possible in limited retrohepatic space. Herein, we describe the "Single oval ostium technique" using dual synthetic vascular grafts ensuring a common outflow channel for all the hepatic veins.
