    Abstract:
    BACKGROUND: Anomalous portal vein (PV) branching in living donor livers is not uncommon and usually leads to double PV orifices of the right lobe grafts. We have assessed the long-term outcomes of portal Y-graft interposition for adult living donor liver transplantation (LDLT). METHODS: We retrospectively assessed the outcomes of 79 right-lobe LDLTs using portal Y-graft interposition among the 2001 adult LDLTs performed at our institution from January 2002 to December 2010. RESULTS: Donor PV types were type III except for one case of type II. Sources of Y-grafts were recipient autologous PV in 76 LDLTs, fresh iliac vein allografts in two, and patch plasty using recipient greater saphenous vein in one. Detailed procedures included a portal Y-graft resection with Y-limbs, corner stay sutures, tying of suture materials under direct mechanical dilatation, and direct edge-to-edge anastomosis to the recipient remnant main PV. Early PV stenting was necessary in five patients (6.3%) due to stenosis or buckling deformity. During a mean follow-up of 42 months, all PVs remained patent until patient death or censoring. Overall 1-, 3-, and 5-year patient survival rates were 93.6%, 88.3%, and 85.5%, respectively. None of the 79 donors experienced major complications requiring reoperation or therapeutic intervention. CONCLUSIONS: Due to their technical feasibility and excellent long-term outcome, portal Y-graft interposition should be considered a standard procedure for reconstruction of right-lobe grafts with double PV orifices.
