Anterior Sector Outflow Reconstruction Using Polytetrafluoroethylene (PTFE) Graft in Right Lobe Living Donor Liver Transplantation: A Step towards Donor Safety and Optimising Recipient Outcomes

Abstract

Outflow reconstruction in right lobe living donor liver transplantation (RL-LDLT) is critical; especially in liver allografts without middle hepatic vein (MHV). Preserving the MHV with the donors add to donor safety but leads to multiple segmental veins in the graft, which have impact on segmental regeneration of allograft and can cause graft dysfunction. As an institutional policy, we routinely preserve the MHV with donor and reconstruct the anterior sector venous tributaries in recipient. We have been using expanded polytetrafluroethylene (ePTFE) vascular graft to reconstruct the anterior sector tributaries in RL-LDLT.
