【摘要】 目的 门静脉(PV)彩色多普勒(CDFI)超声对诊断肝硬化的意义。方法 运用CDFI超声检查了40例肝硬化患者的PV，并按Puph肝功能分级法进行统计学处理。结果 脉冲多谱勒(PW)可显示血流速度正常，减低或双向血流;血流速度、血流量随着Puph肝功能分级程度严重而下降;与正常组比较差异有显著性(P<0.05);肝硬化患者疾病组治疗NO、ET-1的含量均高于正常对照组(P<0.05)，治疗后均低于治疗前(P<0.05);并随着肝硬化严重程度其水平不断上升(P<0.05～0.01);肝硬化组ET-1与NO含量呈正相关，(r=0.654，P<0.01);血浆NO含量与Vpv、Vsv及Dsmv呈负相关(r=-0.415、r=-0.359、r=-0.433，均P<0.05)。结论 CDFI检测门静脉不仅能诊断肝硬化，而且能判断肝硬化损害的程度。
