Abstract:
Objective To evaluate graft regeneration and influencing factors after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-three living recipients were included in this study.We measured graft volume periodically by using MSCT and IQQA-Liver workstation.The liver regenerative ratio (LRR) of different stages of recipients after LDLT was calculated and compared,and stepwise regression analysis was done to set up the regression equation.Result Within 0.5 month after LDLT,graft volume was increased rapidly,and LRR reached maximum [(106.11 + 30.90)％],then decreased slowly.There was significant difference in LRR among 0.5,1 month and 3,6 months after LDLT (P＜0.05).The following factors,including whether the graft containing middle hepatic vein or not,age and sex of recipients,had no significant influence on LRR after LDLT (P＞0.05).The status of liver function of recipients preoperatively had significant influence on LRR 0.5 month after LDLT (P＜0.05).There was significantly negative correlation between the graft volume and LRRs of recipients at different stages after LDLT (P ＜ 0.05).Regression equation could be derived.Conclusion Most evident graft regeneration occurs in early stage after adult LDLT.There are many and different factors influencing graft regeneration at the different stages after LDLT.Graft volumetric measurement by using MSCT is a valid modality to evaluate graft regeneration after LDLT.
