Methods Three hundred fourteen right lobe living donor liver transplantation patients were divided into 2 groups: 163 patients using right hepatic artery as the recipient vessel and 151 patients using left hepatic artery as the recipient vessel. Cases involving 2 recipient blood vessels or the use of other blood vessels as recipient vessels were excluded. Results Overall vascular embolism rate in both groups was 1.3%, and our complication rate was lower than those in previous studies. There was no significant difference in complication rate between the groups, but a significant difference in recipient/donor artery size ratio was noted. Conclusions Although left hepatic artery's anatomical position makes it less affected by bile duct anastomosis and thus fewer postoperative complications, we believe that the ratio of the donor-recipient blood vessel size and the length of the anastomosis vessel stumps are the key factors that affect the outcome of the vascular anastomosis.
