Abstract：Liver transplantation (LT) is the most effective method for endstage liver disease. Split liver transplantation (SLT) is an effective method to enlarge the number of liver grafts. However, because of the existence of portal vein variations, right hemi-grafts splitting and recipients’ portal vein (PV) reconstruction might be more challenging [ 1 , 2 ]. According to the origins of intrahepatic PV branches, Nakamura and his coworkers [3] classified PV variants into five classes (Fig. S1): type A to E. It is reported that the standard anatomy in PV branching pattern accounts for only 65% of investigated population, and that the most common anatomic variation of main portal vein (MPV) is trifurcation variation followed by right posterior portal vein (RpPV) as a first branch of MPV [4] . Type C and D variations are the two most technique highly demanding types. The variation of PV in donated liver graft still challenges surgeons, especially in the field of SLT. There is still a lack of a common sense about the modality of complicated variations in PV reconstruction. Here, we presented two complicated SLT cases, existence of type C and D PV variations in grafts, respectively.
