摘要 目的:探讨不同阶段肝硬化患者肾血流动力学的变化,评价彩色多普勒血流显像技术(CDFI)对该种患者肾早期病变的诊断价值。方法:应用CDFI监测30例肝硬化患者和20名健康对照者的各段肾动脉阻力指数(RI)。结果:肝硬化患者肾动脉RI由肾门至肾皮质依次降低的规律消失,肝硬化的肾主动脉、叶间动脉、小叶间动脉的RI比正常对照组有显著增高(P<0.05),失代偿期大量腹水肾动脉RI的升高更显著,而血清肌酐、尿素氮水平与对照组相比差异无显著性。结论:应用CDFI监测肾动脉RI可为判断肝硬化患者早期肾功能损害提供较敏感的指标。从肾门到皮质动脉阻力梯度降低的趋势消失为研究肝肾综合征的发病机制提供了直观的血流动力学信息,对肝硬化腹水的治疗观察、肝肾综合征的预测有重要的参考价值。
