目的 研究肝硬化患者肾脏血液动力学的改变。方法 应用多普勒超声测定 42例肝硬化患者肾脏血液动力学指标 ,并分析这些指标与肝功能及平均动脉压之间的关系。结果 不同阶段的肝硬化患者肾内血管收缩程度有明显的差异。结论 肝硬化早期即有肾血管的收缩 ,肝功越差肾血管收缩越明显 ,肾血管的收缩是全身血液动力学改变的一部分。
Objective To study the changes of renal hemodynamics in cirrhotic patients. Methods 42 cases of liver cirrhosis patients with hematological parameters were measured by Doppler ultrasound and the relationship between them and liver function and mean arterial pressure was analyzed. Results There were significant differences in the extent of renal vasoconstriction in patients with cirrhosis at different stages. CONCLUSIONS: Renal vasoconstriction occurs early in cirrhosis and the worse the liver function is, the more obvious the renal vasoconstriction is. The contraction of the renal vasculature is a part of systemic hemodynamic changes.
