Objective Optimal hepatic venous tributary flow is correlated with liver function and regeneration. In left-lobe graft living donor liver transplantation, the stump of segment 5 and 8 hepatic veins (S5V and S8V) are ligated without performing hepatic tributary reconstruction. The aim of this article was to evaluate the different dominate hepatic vein patterns that affect left-lobe living donor safety. Materials and Methods A total of 44 donors who underwent left-lobe hepatectomy were divided into 2 groups, middle hepatic vein (MHV) dominance (group 1) and right hepatic vein (RHV) dominance (group 2), according to the dominant venous territory drainage from S5V and S8V or RHV. The clinical pathological data, postoperative laboratory data, complication, remnant liver volume and remnant liver regeneration rate at 6 months after surgery were compared. Results No difference was found in blood loss, postoperative liver function such as alanine transaminase value, complications, and hospital stays between groups. Group 1 had slightly higher total bilirubin level than group 2 (1.99 vs 1.79; P =.49). Group 2 had significantly better remnant liver regeneration rate than group 1 (89.2% vs 82.5%; P =.026). Conclusion It is important to recognize the dominant MHV group. Ligation large S5V and S8V in dominant MHV donors led to lower remnant liver regeneration in our series. This might be critical in extremely small RHV territory and potential large remnant liver congestion donors. Adjusting surgical planning, such as hepatic vein reconstruction, in this kind of donor might be appropriate for donor safety.
