    Abstract:
    A right liver graft with multiple hepatic artery (HA) stumps can be found in approximately 5% of living donor liver transplantation (LDLT) using a right lobe graft. From January 2000 to June 2014, 1149 patients underwent LDLT procedures. Thirty patients with LDLT using a right lobe graft with multiple HA stumps and 149 patients with LDLT using a right lobe graft with a single HA stump were enrolled. These patients were divided into 3 groups: single HA (group 1, n = 149), multiple HAs with total reconstruction (group 2, n = 19), and multiple HAs with selective partial reconstruction (group 3, n = 11). Selective partial reconstruction was performed only when pulsatile back-bleeding was confirmed after larger HA reconstruction and sufficient intrahepatic arterial flow was confirmed by Doppler ultrasound (DUS). In group 2, the donor HAs were smaller (P < .001), and HA reconstruction took longer (P < .001). However, there was no significant difference among the groups regarding the arterial complication rate, biliary complication rate, and patient and graft survival. In conclusion, selective partial reconstruction of HA stumps for LDLT using a right lobe graft was feasible when intrahepatic arterial communication was confirmed by pulsatile back-bleeding from the smaller artery and DUS.
