Venous outflow reconstruction in living donor liver transplantation: Dealing with venous anomalies

Figure 5 “Single-Oval Ostium” technique. A: Right liver graft with multiple IRHVs draining randomly. V8 and IRHVs are incorporated in a single lumen using dual ePTFE grafts; B: Right liver allograft with the major IRHV located 10 cm from the RHV. Single wide outflow is reconstructed for the V8 and IRHV; C and D: Outflow reconstruction using Single-Oval Ostium technique. RHV: Right hepatic vein; IRHV: Inferior right hepatic vein; ePTFE: Expanded polytetrafluoroethylene; IVC: Inferior vena cava; V8: Venous tributaries of segment 8.
