目的:探讨颈动脉粥样硬化与缺血性脑血管病的关系。方法:彩超检查280例缺血性脑血管病患者的颈动脉,测量血管的直径、内-中膜的厚度(IMT),血流的速度等参数,观察斑块的有无及形成情况,并检查200例健康志愿者作为对照组。结果:280例缺血性脑血管病患者中,颈动脉有粥样硬化、血管重构、IMT增厚、斑块形成、管腔狭窄等血管异常者240例,检出率达85.7%;对照组中有IMT增厚和软斑形成34例,检出率为17.0%,二者比较有显著差异(P<0.01)。结论:缺血性脑血管病和颈动脉粥样硬化存在着线性关系;高频彩超诊断技术,对项动脉粥样硬化检出预报和疗效的观察、评价有重要意义。
Objective: To investigate the relationship between carotid atherosclerosis and ischemic cerebrovascular disease. Methods: The carotid arteries of 280 patients with ischemic cerebrovascular disease were inspected by color Doppler ultrasound. The diameter of blood vessel, the thickness of intima - media (IMT) and velocity of blood flow were measured. The presence and absence of plaque and its formation were observed. 200 healthy volunteers were examined as control group. Results: Of the 280 patients with ischemic cerebrovascular disease, 240 cases of carotid artery atherosclerosis, vascular remodeling, IMT thickened, plaque formation, stenosis and other vascular abnormalities, the detection rate was 85.7%; control There were 34 cases of IMT thickening and plaque formation in the group, the detection rate was 17.0%, there was significant difference between the two groups (P <0.01). Conclusion: There is a linear relationship between ischemic cerebrovascular disease and carotid atherosclerosis. High-frequency color Doppler ultrasound diagnosis is of great significance for the observation and evaluation of the detection and treatment of atherosclerosis.
