彩色多普勒超声在脑梗死患者颈动脉粥样硬化诊断中的应用

Application of color Doppler ultrasonography in the diagnosis of the carotid atherosclerosis in patients with cerebral infarct

目的初步探讨脑梗死患者颈动脉硬化病变的超声影像特点。方法应用彩色多普勒超声对55例临床上确诊的脑梗死患者和58例正常对照组行颈动脉检测。结果脑梗死组颈动脉粥样硬化及斑块发生率(74.5%)明显高于对照组(15.5%),且随年龄增长呈上升趋势。动脉硬化斑块发生部位以颈动脉分叉部多见(50.4%)。在斑块的4种超声分型中,以扁平斑和软斑发生率为高。结论超声检测颈动脉粥样硬化对预测和治疗脑梗死有重要的临床意义。

Objective To investigate the ultrasonic imaging features o f carotid atherosclerosis in patients with cerebral infarct.Methods Color Dopple r ultrasonography was performed in 55 patients with clinically proved cerebral i nfarct and 58 normal controls.Results The incidence of carotid atherosclerosis a nd its plaque formation (74.5 % ) in patient group was significantly higher tha n that (15.5 % ) in control group and it was continuously increased with age ag ing.The most common position of atherosclerosis plaque was carotid bifurcation ( 50.4 % ).Among four patterns of atherosclerosis plaque on ultrasonic images,the incidence of flat plaque and soft plaque was higher.Conclusion The ultrasonic e xaminations of carotid atherosclerosis have an important significance for predic ting the prognosis of patients with cerebral infarct and for selecting the treat ment protocol.
