缺血性脑血管病彩色多普勒、经颅多普勒联合检测结果分析

Relationship between cerebral ischemic stroke with stenosis and atherosclerosis of carotid and internal carotid artery

目的研究缺血性脑血管病发病与颈部动脉粥样硬化狭窄程度和斑块性质的关系。方法采用彩色多普勒和经颅多普勒技术对缺血性脑血管病患者100例及健康者40例(对照组)进行检测,观察颈动脉解剖形态、内膜情况,有无斑块形成及斑块大小、形态、回声特征,颅内外动脉管腔是否狭窄和狭窄程度。结果缺血性脑血管病组颈动脉不均质、不规则斑块的检出率及其颅内外动脉狭窄的比例均明显高于对照组,且颅内动脉狭窄的比例高于颅外动脉。结论颈动脉粥样硬化斑块的性质及颅内外动脉狭窄与缺血性脑血管病的发生密切相关。

[ Objective] To study the relationship between cerebral ischemic stroke （CIS） with stenosis and atherosclerosis of carotid and internal carotid artery, and study the etiology of CIS. [ Method] 100 cases with CIS as investigate group and 40 cases as normal control group. All were examined by using color doppler flow imaging （CDFI） and transcranial doppler （TCD）. The lumen diameter, intimamedia thickness , plaque, echo-character of plaques of carotid artery were studied. The severity of artery stenosis of internal carotid artery and external carotid artery were also studied. [ Result] The prevalence of irregular and heterogeneous plaques in patients with CIS was higher than those of control group. The occurrence rate of stenosis with internal carotid artery （ICA） and external carotid artery （ECA） was higher than those of control group . The occurrence rate of stenosis with ICA was higher than those of ECA. [ Conclusion] There was a close relationship between CIS and atherosclerosis of carotid artery, stenosis of ICA and ECA. The stenosis was more seen at ICA. There was a close relationship between stenosis in any location and CIS.
