中文摘要:

目的探讨颈动脉结构的形态学改变以及血流动力学变化与缺血性脑血管病的关系,寻找早期诊断缺血性脑血管病的超声指标。方法对137例受检者包括:脑梗死组38例,短暂性脑缺血发作(TIA)组59例及对照组40例,运用彩色多普勒超声技术对其颈总动脉及分叉处的内-中膜厚度(IMT)和斑块情况进行测定,同时测定两侧颈总动脉、颈内动脉、椎动脉血流变化指标:收缩期峰值血流速度(PSV)、舒张末期血流速度(EDV)、PSV/EDV、血管阻力指数(RI )、血管搏动指数(PI)、血流量,并进行对照分析研究。 [HTSS]结果 ①脑梗死组的IMT明显高于TIA组与对照组,TIA组与对照组无明显差异;脑梗死、TIA组与对照组的颈动脉斑块检出率分别为73.7%、28.8%和25%,脑梗死组斑块检出率最高。②与其他两组相比较,TIA组的 PSV、EDV和PSV/EDV均减低,PI和RI均增高,脑梗死组的血流量下降最明显。③通过判别分析表明,可以通过对超声指标的测量预测缺血性脑血管病的发生。结论颈动脉多普勒超声可为缺血性脑血管病患者提供早期诊断和检测的指标。

英文摘要:

Objective To assess the morphologic and hemodynamic changes of extracranial carotid atherosclerosis in ischemic cerebrovascular disease and to find earl y index of diagnosing ischemic cerebrovascular disease.Methods One hundred and thirty-seven cases including 38 patients with cerebrovascular infarction, 59 patients with transient ischem ic attacks (TIA) and compared with 40 control groups were examined with color dop pler ultrasonography to measure carotid intima-media complex thickness (IMT)、car otid plaque and carotid hemodynamic index.Results ①The IMT in cerebrovascular i nfarction groups were higher than in TIA and normal control groups; The prevalenc e of carotid plaque in cerebrovascular infarction groups,in TIA,in control gro ups were 73.7%、28.8% and 25%, respectively.The prevalence of carotid plaque in cerebrovascular infarction groups was the highest in three groups.②Compared wi th other groups, There were significant hemodynamic changes in TIA groups.The p eak systolic velocity (PSV) and end of diastolic velocity (EDV) were high, pulsat ility index (PI) and resistance index (RI) were low in TIA.Volume was the lowest in cerebrovascular infarction groups.③By Discriminant,We got three equations to predict ischemic cerebrovascular disease.Conclusion Carotid artery ultrasonography can provide an index for early diagnosing ischemic cerebrovascular disease.
