The strong association between Small-for-size syndrome and portal hyperperfusion in Living-donor liver transplantation has aroused the need for prevention of graft overperfusion and portal hypertension aiming at improving patient survival.This can be achieved through intra-operative portal venous pressure measurement and modulation of portal graft inflow accordingly.The aim of this work is to illustrate the merits of intra-operative portal venous pressure measurement in LDLT and to study the influence of portal venous pressure and the effects of graft inflow modulation on postoperative graft function.
