The purpose of the present study is to evaluate new criteria for donor selection in living donor liver transplantation(LDLT)of the small-for-size liver graft.We have tried to grasp the post operational changes of hepatic veins in a three dimensional asepect,and designed a new procedure for hepatic vein reconstruction so as to accommodate the changes.This not only gives patients who had been formerly considered to be outside the liver transplantation criteria because of the absent of donor with enough graft volume a chance to safely undergo transplantations, but has also implies the possibility of improving the safety of donor, which is the primary importance in LDLT.Our study has obtained a result of high significance.
