摘　　要：目的:探讨颈动脉彩色多普勒超声对脑卒中高危人群的评估作用。方法:我院2015年3月至2017年3月接收的脑卒中高危人群500例作为研究对象,了解患者一般病史,均采取颈动脉彩色多普勒超声成像进行检查,分析脑卒中高危人群形成颈动脉斑块或狭窄的主要危险因素,以及年龄对患者颈动脉斑块、狭窄发生率的影响。结果:①500例脑卒中高危风险患者的颈动脉超声结果显示,出现颈动脉内中膜增厚以及颈动脉斑块形成的患者分别180例和141例,分别占总高危人群的36.00%和28.20%。②随着年龄的增长,颈动脉内中膜增厚、颈动脉斑块成型、颈动脉狭窄患者的占比明显升高(P<0.05)。③男女患者颈动脉形成斑块的比例有统计学差异(P<0.05)。④logistic回归显示,高血压、高血脂、缺乏运动、脑卒中家族史4项指标是导致脑卒中高危状态/颈动脉内中膜增厚的危险影响因素。结论:卒中高危人群中,颈动脉内中膜增厚和动脉粥样硬化斑块的发生率均有随着年龄增加而增加的趋势。颈动脉彩色多普勒超声对脑卒中风险评估中有较高的诊断价值,值得临床应用。Objective:To investigate the value of carotid artery sonography in screening for the high-risk population of stroke.Methods:A total of 500 patients at a high risk of stroke who were admitted to our hospital from March 2015 to March 2017 were enrolled as subjects,and their medical history was recorded.Carotid artery color Doppler ultrasound was performed for all patients,and risk factors for carotid plaque or stenosis in the high-risk population of stroke were analyzed,as well as the influence of age on the incidence rates of carotid plaque and stenosis.Results:The results of carotid artery sonography showed that among the 500 patients at a high risk of stroke,180(36.00%)had carotid intima-media thickening and 141(28.20%)had the formation of carotid plaque.The proportion of patients with carotid intima-media thickening,formation of carotid plaque,and carotid stenosis significantly increased with age(P<0.05).There was a significant difference in the proportion of patients with the formation of carotid plaque between male and female patients(P<0.05).The logistic regression analysis showed that hypertension,hyperlipidemia,lack of exercise,and a family history of stroke were risk factors for high risk of stroke or carotid intima-media thickening.Conclusion:In the population at a high risk of stroke,the incidence rates of carotid intima-media thickening and atherosclerotic plaques tend to increase with age.Carotid artery color Doppler ultrasound has a high value in the risk assessment of stroke and thus holds promise for clinical application.
