颈动脉彩超在临床诊断脑梗死中的应用价值分析

目的探讨彩超检测脑梗死患者颈动脉粥样硬化斑块的临床价值。方法利用彩超对86例经CT和（或）MRI确诊脑梗死患者的颈动脉内中膜厚度（IMT）、斑块类型及斑块形态进行检测，并设立45例非脑梗死患者为对照组。同时检测两组的血流动力学参数。结果脑梗死组发现86例颈动脉有不同程度的粥样硬化斑块形成，发生率79．1％。患病组颈动脉IMT（1．22±0．31）mm]较对照组IMT（0．60±0．14）mm]明显增厚，有统计学意义（P〈0．05）；患病组颈动脉斑块以脂质型为主，且表面多呈不规则型。结论脑梗死患者颈动脉IMT较对照组增厚，粥样硬化斑块以脂质型为主，说明粥样斑块的性质与脑梗死的发生密切相关。

Color Doppler Ultrasonic Assessment of Carotid Atherosclerotic Lesions in Diagnosis of Brain Infarction

Objective To explore the clinical value of color Doppler ultrasound in patients with cerebral infarction detection carotid atherosclerotic lesions Methods Use of 86 cases exceeds by CT and （or） MRI diagnosed patients with cerebral infarction of carotid intima-media thickness（IMT）,patch types and plaques form for testing,45 cases of patients with no cerebral infarction as control group. Meanwhile testing two group of hemodynamic parameters. Results Different degrees of carotid atherosclerotic plaque formation was found in 86 cases of cerebral infarction group,incidence 79.1%. Prevalence of carotid IMT （1.22 ±0.31）mm was significantly thicker, than in the control group IMT （0.60±0.14） mm with a significant diffrence（P〈0.05）Sick with carotid plaques of lipid main type,and the surface much an irregular shape. Conclusion IMT carotid artery thickening than the control group, type of atherosclerotic plaque lipid-based,indicating the nature of atherosclerotic plaque is closely related to the occurrence of cerebral infarction.
