研究肝硬化病人外周动脉血流参数变化，采用彩色多普勒超声检测了30例早期肝硬化病人，34例中晚期肝硬化病人及20例正常人的肱、股动脉血流参数。结果显示：中晚期肝硬化的肱，股动脉收缩期峰值流速（ＰＳＶ），平均瞬时流速（ＴＡＭｎ），血流量（Q），明显低于对照组（ｐ＜０．００１），肱股动脉血管直径（Ｄ）阻力指数（ＲＩ）和搏动指数（ＰＩ）早期、中晚期肝硬化组与正常组比较无差异。肝硬化后会导致外周动脉血流动力学参数改变，这对于肝硬化的诊断，病情改变的检测，以及肝硬化引发的高动力循环状态的基础研究，都有一定的价值。
The changes of peripheral arterial blood flow parameters in cirrhotic patients were studied. The brachial and femoral arterial blood flow parameters of 30 patients with early liver cirrhosis, 34 patients with advanced liver cirrhosis and 20 healthy controls were detected by color Doppler sonography. The results showed that the peak systolic velocity (PSV), mean transient velocity (TAMn) and blood flow (Q) of the brachial and femoral arteries in patients with advanced liver cirrhosis were significantly lower than those in the control group (p <0.001) Diameter (D) resistance index (RI) and pulsatility index (PI) early and advanced liver cirrhosis group compared with the normal group no difference. Cirrhosis will lead to peripheral arterial hemodynamic parameters change, which for the diagnosis of cirrhosis, detection of disease changes, as well as cirrhosis-induced hyperdynamic circulation of basic research, have some value.
