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

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。

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

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.
