Abstract： 目的利用彩色多普勒超声检测移植肝血流动力学的参数,探讨参数变化的临床意义.方法利用彩色多普勒超声检测65例肝移植患者不同时期的肝动脉、肝静脉及门静脉的峰值血流速度(PS)、时间平均血流速度(TAV)、阻力指数(RI)及肝动脉血流灌注指数(DPI).结果术后15 d内,移植肝正常者门静脉TAV及肝动脉RI均明显高于对照组(P＜0.05);肝动脉PS及DPI均明显低于对照组(P＜0.05).肝动脉血栓形成时,肝动脉PS明显降低,门静脉TAV明显增高,呈锯齿波.发生排斥反应时,门静脉TAV降低,肝动脉PS降低、RI增高,肝静脉三相波消失,呈锯齿波.结论利用彩色多普勒超声监测移植肝的血流动力学参数变化,可为移植肝的血管并发症及排斥反应的诊断提供辅助依据,且安全、无创.
