【摘要】 目的 应用彩色多普勒超声(CDFI)探讨肝硬化患者的血流动力学改变的意义。 方法 本文观察了100例肝硬化患者的门静脉(PV)宽度、血流速度、肝静脉频谱形态、肝动脉(HA)和肠系膜上动脉(SMA)的血流速度、阻力指数(RI)等项参数，并与80例健康成人进行对照。 结果 显示肝硬化患者PV增宽，血流速度明显低于对照组;肝静脉频谱的负向波减低或消失;肝动脉显示率提高达98%(98/100)，明显高于对照组。SMA的RI减低。 结论 本文观察的结果认为CDFI检查对肝硬化的诊断及病情变化的监测有一定的临床意义。

    【Abstract】 Objective To study significance of the changes of hemodynamics in liver cirrhosis was detected by color Doppler flow imaging(CDFI).Methods 100patients with liver cirrhosis were selected to determine the width of portal vein，velocity of blood flow，morphology of hepatic venous frequency spectrum;blood flow velocity and resistance index(RI)of the hepatic artery and superior mesenteric artery ......
