摘　　要：To the Editor: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.
