彩超对颈动脉粥样硬化与缺血性脑血管疾病关系的研究

目的研究彩超对颈动脉粥样硬化与缺血性脑血管疾病的关系。方法应用彩色多普勒超声对60例确诊为缺血性脑血管疾病患者的颈动脉进行血管内径测量,内膜-中膜厚度(IMT)测量,观察有无斑块形成和血管狭窄情况,并与我院同期体检的健康志愿者60例作对照。结果病变组IMT增厚6例(10.0%);斑块形成者37例(61.7%),其中软斑9例、硬斑17例、混合斑11例;颈动脉狭窄13例(21.6%),其中轻度狭窄4例,明显狭窄6例,1例患者出现左颈动脉的闭塞。对照组IMT增厚6例(10.0%),斑块形成者2例(3.3%),管腔轻度狭窄1例,无管腔明显狭窄及闭塞病例;病变组与对照组CCA分别为(6.88±0.81)mm、(6.01±0.54)mm,两组比较差异具有统计学意义,P<0.05;病变组与对照组EDV分别为(22.63±6.03)mm、(27.14±5.98)mm,两组比较差异具有统计学意义,P<0.05;病变组与对照组PSV分别为(56.14±5.33)mm、(77.54±21.53)mm,两组比较差异具有统计学意义,P<0.05。结论颈动脉粥样硬化与缺血性脑血管疾病呈线性关系,彩超作为一种无创检测,简单易行,对缺血性脑血管病的早期诊断具有较高的准确性,对颈动脉粥样硬化与缺血性脑血管疾病的防治具有重大意义。

Color Doppler Ultrasound to the Study of the Relationship between Carotid Atherosclerosis and Ischemic Cerebrovascular

Objective To study the Color Doppler ultrasound to the relationship between carotid atherosclerosis and ischemic cerebrovascular.Methods 60 patients diagnosed with ischemic cerebrovascular were measured the blood vessel diameter of carotid artery and intima-media thickness（IMT） by Color Doppler ultrasound,and observed whether it had plaque formation and vascular stenosis,then compared with 60 cases of healthy volunteers in Heze Mudan district central hospital at the same period.Results 6 patients（10.0%） had IMT thickening in lesions group;37 cases had plaque formation（61.7%）,including 9 cases with soft spots and 17 cases with hard spots,11 cases had mixed plaques;13 cases had carotid artery stenosis（21.6%）,4 cases had mild stenosis,6 cases had obvious stenosis and 1 patient had left common carotid artery occlusion.6 patients（10.0%） had IMT thickening in control group;2 cases（3.3%） had plaque formation,1 case had mild luminal stenosis,no cases had luminal stenosis and occlusion;CCA in lesion and control group was respectively（6.88±0.81）mm,（6.01±0.54）mm,the difference was statistically significant,withP〈0.05;EDAin lesion and control group was respectively（22.63 ±6.03）mm,（27.14±5.98）mm,the difference was also statistically significant,withP〈0.05;PSV in lesion and control group was respectively（56.14±5.33）mm,（77.54±21.53）mm,the difference was statistically significant,with P〈0.05.Conclusion Carotid atherosclerosis and ischemic cerebrovascular disease had linear relationship,the Color Doppler ultrasound as a noninvasive test is simple,and it has high accuracy in the early diagnosis of ischemic cerebrovascular disease and it has great significance to the prevention of carotid atherosclerosis and ischemic cerebrovascular disease.
