摘要 目的探讨肝硬化门脉高压患者门脉系统血流动力学参数变化及其临床意义。方法应用多普勒超声检测50例肝硬化门脉高压症患者门脉系统血流动力学参数,并以18例正常体检患者对照研究。分析两组间门脉系统相关血管血流动力学参数差异。结果病例组门静脉、脾静脉和脾动脉血管内径及其血流量较对照组均呈显著性增大(P<0.01),血流速度亦有增加,但无统计学显著意义(P>0.05)。病例组脾静脉血流量/门静脉血流量(Qp/Qsv)为82.4%(1360.60/1650.57),而对照组脾静脉血流量/门静脉血流量(Qp/Qsv)仅为37.7%(364.31/965.69),两组间比较具有统计学显著性意义(P<0.01)。结论门静脉高压患者存在门静脉系统血流动力学变化。提示其在门静脉高压症的发病机制中起重要作用。
