Abstract:
Objective To evaluate the hemodynamic changes and vascular complications after pediatric living donor liver transplantation (LDLT).Methods The hemodynamic changes of the portal vein,the hepatic artery and the left hepatic vein of the 34 cases were evaluated by color Doppler ultrasound during 2 months after LDLT.The vascular complications after LDLT were also evaluated.Results Of the 34 cases,vascular complications occurred in 5 cases.One day after LDLT,the max velocity of portal vein was (53.97 ± 21.44) cm/s,the peak systolic velocity of hepatic artery was (52.88 ± 17.87) cm/s,the resistance index was 0.73 ± 0.09,the max velocity of left hepatic vein was (40.53 ± 25.07) cm/s.The parameters of the hemodynamics had no significant difference between 1day and 1 week after LDLT (P＞0.05).The max velocity of portal vein was decreased after 2 weeks (P＜0.05).After 2 months,the max velocity of portal vein and the peak systolic velocity were decreased (P＜0.01 and P＜0.05) compared to 1 day.Vascular thrombosis was found in 5 recipients and all occurred in the first week after LDLT.Hepatic artery thrombosis (HAT) occurred in 3 (8.8 %) cases,portal vein thrombosis (PVT) in 2 (5.9 %).Among the 5 cases,3 were died.Conclusion The max velocity of portal vein and the peak systolic velocity of hepatic artery were decreased gradually after LDLT.The vascular complications occurred in the early stage and had a relatively high rate.Doppler examination should be performed once every day within 7 post-transplant days.
