彩色多普勒超声检查肝硬化患者肾动脉血流参数的价值

The value of color Doppler in the detection of renal artery blood flow parameters in patients with cirrhosis

目的探讨肝硬化患者各级肾动脉血流动力学变化。方法使用彩色多普勒超声检测46例代偿期和56例失代偿期肝硬化患者肾动脉(MRA)、段动脉(SRA)和叶间动脉(IRA)的RI、PI、Vmax和Vmix。结果代偿期肝硬化患者各级肾动脉RI、PI、Vmax、Vmix与正常组比无明显的差异(P>0.05),而失代偿期患者与正常组比有显著性差异(P<0.01);失代偿期肝硬化各级肾动脉血流速度减低,而PI、RI增高,肾动脉RI由MRA至IRA依次降低的规律消失。结论检测肝硬化患者肾动脉血流参数的变化,对了解肾脏病情的进展有帮助。

Objective To explore the characteristics of renal artery blood flow parameters at all levels in patients with cirrhosis. Methods Renal artery blood flow parameters at all levels were detected by the use of color Doppler ultrasound in 46 patients with compensated,56 with decompensated liver cirrhosis and in control. The renal artery （MRA）,segmental arteries（SRA）,interlobar artery（IRA）were selected to detect. Results Compared with control group,Ri,PI,Vmax and Vmix in compensated cirrhosis were not significantly different（P〉0.05）, but the same indexes in decompensated cirrhosis group changed with obvious difference （P〈0.01）. Blood flow velocitis of renal artery in different levels of patients with decompensated cirrhosis decreased. Conclusions The detection of renal artery blood flow parameters would provide a valuable basis in understanding the kidney disease progression.
