血管回声跟踪技术评价脂肪肝患者颈动脉弹性功能

Evaluation of carotid elasticity function in fatty liver patients by echo-tracking technique

目的应用血管回声跟踪(ET)技术评价脂肪肝患者颈动脉弹性功能。方法选取我院超声科诊断为均匀性脂肪肝的患者78例(脂肪肝组),依据综合积分值将其分为轻、中、重度组,另选同期体检的健康体检者40例(正常对照组)。应用ET技术测量各组患者的颈动脉弹性参数,比较轻、中、重度脂肪肝患者组间及各脂肪肝组与正常对照组间有无差异。结果脂肪肝各组分别与正常对照组比较,颈动脉弹性参数僵硬度(β)、压力应变弹性系数(Eρ)、脉搏波传导速度(PWVβ)值均增高,血管顺应性(AC)值均降低,差异均有统计学意义(P<0.05);与轻、中度组比较,重度组β、Eρ、PWVβ值均增高,AC值降低,差异均有统计学意义(P<0.05);轻、中度组各指标间比较无明显差异。结论 ET技术可对脂肪肝患者的颈动脉弹性功能进行早期的有效评估。

Objective To evaluate the carotid elasticity function in fatty liver patients by echotracking （ET） technique. Methods Seventy-eight patients with uniformity fatty liver were enrolled in this study as fatty liver group, they were divided into mild, mediate and severe group according to their total of scores. At the same time 40 same period healthy subjects were selected as normal group. The carotid elasticity parameters of each group were mesured by ET technique, then the results were compared. Results Compared with normal group, stiffness parameters （β）, pressure-strain elastic modulus （Ep）, pulse wave velocity （PWVβ） in mild, mediate, severe group were increased, artery compliance（AC） was decreased, there was significant difference（P〈0.05）. Compared with mild and mediate group, β, Ep, PWVβ in severe group were increased, AC was decreased, there was significant difference （P〈0.05）. While there was no significant difference between mild and moderate group. Conclusion ET can be used to early access carotid elasticity function in fatty liver patients.
