摘　　要：目的:探讨血管回声跟踪(echo-tracking,ET)技术检测肝硬化患者颈动脉弹性功能指标β、Ep、AC、AI、PWVβ及其意义．方法:应用ET技术检测20例肝硬化患者颈动脉的弹性指标,包括僵硬度参数β、压力应变弹性系数Ep、动脉顺应性AC、脉搏波放大指数AI及脉搏波传递速度PWVβ,并采用协方差分析与同期检查的150例正常人进行比较．结果:排除年龄因素影响后,肝硬化组与正常人相比颈动脉的β、AI有差别(P=0．02;P= 0．00),Ep、AC、PWVβ差异无差异(P>0．05)．结论:肝硬化患者的颈动脉弹性较正常人差; ET术能够定量检测肝硬化患者的颈动脉弹性功能改变．AIM： To quantitatively detect the carotid elasticity in patients with liver cirrhosis by echo-tracking （ET） technique. METHODS： ET technique was used to determine the stiffness parameter （β）, pressure-strain elasticity modulus （Ep）, arterial compliance （AC）, argumentation index （AI） and one-point pulse wave velocity （PWVβ） of carotid in 20 cirrhotic patients and 150 normal adults. RESULTS： The values of β and AI in patients with liver cirrhosis were higher than those in normal adults （P = 0.02; P = 0.00）, while of the values of Ep, AC and PWVβ were not markedly different between cirrhotic patients and normal adults （P 〉 0.05）. CONCLUSION： The carotid elasticity in cirrhotic patients is decreased, and it can be detected quantitatively by ET technique.
