缺血性脑卒中患者颈动脉内膜中层厚度与脑循环动力学的关系

Relationship between carotid artery intima-media thickness and cerebrovascular hemodynamic analysis in patients with ischemic stroke

目的 探讨颈动脉内膜中层厚度 (IMT)与脑循环动力学 (CVA)之间的相关性及其对缺血性脑卒中的早期临床诊断价值。方法 应用彩色多普勒超声和CVA检测仪分析 12 0例急性期和超早期缺血性脑卒中患者的颈动脉IMT、IMT/D比率及CVA各项指标。并与健康对照组比较。结果 缺血性脑卒中患者颈动脉IMT及IMT/D比率均明显大于健康成人 ;缺血性脑卒中超早期组Vmean、Qmean比急性期组明显降低 ,而R、DR明显增高 ,超早期组CVA检测阳性率明显高于急性期组。颈动脉IMT及IMT/D比率与Vmean、Qmean呈显著直线负相关 ,与R、Zc呈显著直线正相关。

Objective To investigate the correlation between carotid artery intima media thickness (IMT) and cerebrovascular hemodynamic analysis (CVA) and the diagnostic value in ischemic stroke.Methods Using colour Doppler IMT,IMT/D ratio and CVA were performed in 120 patients with hyperacute and acute ischemic stroke as compared with the health controls.Results IMT and IMT/D ratio were higher in patients with ischemic stroke than the health aduts. Vmean and Qmean in ischemic stroke hyperacute group were lower, and R,DR were higher obvious in hyperacute group than that of acute group. IMT and IMT/D ratio were negatively correlation with Vmean and Qmean and positively correlation with R and Zc.Conclusion The measurement of carotid artery IMT and CVA have clinical significance in early diagnosis of ischemic stroke.
