BACKGROUND: A left liver graft in living donor liver transplantation often has 2 arterial stumps. The indication for multiple arterial reconstructions remains controversial. The aim of this retrospective study was to investigate whether single anastomosis of a left liver graft affects the outcome of living donor liver transplantation. METHODS: When a hepatic graft had 2 arterial stumps, the thicker (dominant) stump was reconstructed first. After the initial reconstruction, another reconstruction was performed only if no pulsating flow was observed from the remnant stump. A total of 134 left liver grafts were divided into 3 groups: Group 1 (n = 70), 1 arterial stump on a graft with 1 arterial reconstruction; Group 2 (n = 59), 2 stumps with 1 arterial reconstruction; Group 3 (n = 5), 2 stumps with 2 arterial reconstructions. The incidence of hepatic arterial thrombosis, biliary stenosis, and patient survival was compared between Groups 1 and 2. RESULTS: The incidence of arterial thrombosis and biliary stenosis, and the patient survival curves, were equivalent between Groups 1 and 2. CONCLUSION: When the criteria were satisfied, single arterial reconstruction in a left liver graft with 2 arterial stumps did not affect the patient survival or biliary complications.
