超声检测肝硬化及非肝硬化病人肝移植患者肝动脉血流流速参数比较

目的探讨肝硬化及非肝硬化后肝移植患者肝动脉血流动力学异。方法 42例肝移植患者根据术前肝功能分为,肝硬化组30例,和非肝硬化组12例。于术后第3天、第5天和第7天分别行肝动脉多普勒超声检查。结果术后第3天、第5天和第7天测得肝动脉血流最大流速,最小流速肝硬化组均低于非肝硬化组(P0.05),阻力指数两组间不存在统计学差异。结论肝硬化肝移植术后7天内肝动脉血流流速低于非肝硬化肝移植患者。

Comparison of flow velocity parameters of hepatic artery in cirrhotic and non-cirrhotic patients after liver transplantation

Objective To investigate the difference of blood flow parameters of hepatic artery in cirrhotic and non-cirrhotic patients after liver transplantation.Methods Accoding to liver function preoperatively,42 patients after liver transplantation were classified into cirrhotic group（n=30） and non-cirrhotic group（n=12）.Blood flow parameters of hepatic artery was examined with color Doppler ultrasonography on the third,fifth and seventh day after liver transplantation,retrospectively.Results The peak systolic velocity and end diastolic velocity of hepatic artery in the third,fifth and seventh day after liver transplantation in cirrhotic group were lower than those in non-cirrhotic group（P0.05）.There was no statistical difference of resistance index between two groups.Conclusion The peak systolic velocity and end diastolic velocity of hepatic artery in seven days after liver transplantation in cirrhotic group are lower than those in non-cirrhotic group.
