缺血性脑血管病患者颈动脉超声影像学分析

目的：探讨缺血性脑血管病（ICVD）与颈动脉粥样硬化（CAS）的关系。方法：将206例患者分为短暂性脑缺血发作（TIA组）和脑梗死（CI组）两组，采用彩色多普勒超声诊断仪检测颈动脉病变情况并与健康体检者（对照组）进行对比分析。结果：（1）CI组CAS检出率高于TIA组（P〈0．05），而且硬斑检出率亦高于TIA组（P〈0．05）；病例组CAS检出率显著高于对照组（P〈0．01）。（2）病例组CAS检出率与年龄有关，但与性别无相关性。结论：（1）CI组CAS检出率高于TIA组，且以硬斑为主；（2）ICVD患者的CAS检出率随年龄增大而增高，但与性别无相关性；（3）采用超声检测颈动脉是发现CAS及其程度的有效方法。

The analysis of carotid atherosclerosis ultrasonic imaging in 206 cases of ischemic cerebral vascular diseases.

Objective：To discuss the relation between ischemie cerebral vascular diseases（ICVD）and carotid ather clerosis（CAS）. Methods： 206 patients who had ICVD were investigated and classified into transient isehemie attack （TIA）group, and cerebral infarction （CI）group, health screening of 60 patients（control group）. The carotid uhrasonicgraphy outcomes, age, gender and the property/locua of atherosclerotic spots were analyzed. Results：（1）The incidence of CAS was significantly higher in CI group than that in TIA group（P〈0.05）. But the CAS severity among the three groups was of no significance（P〉0.05）. （2）There was a positive correlation between the incidence of CAS and the increase of age among the three groups（P〈0. 05） ,but the severity of CAS had no relation with aging（P〉0.05）. （3）Solid CAS plaques happened more frequently among ICVD patients（55.06 % ）, whereas loose and composite CAS plaques was much lower（ 11. 8000 ）. （4）Generally, gender had no correlation with CAS. Conclusions：（1） The incidence of CAS was higher in CI group than that in TIA group. （2）Aging affected the incidence of CAS among ICVD patients,but it has no relation with the severity of CAS. （3）Among ICVD patients, most of the CAS was solid plaques. （4）Generally,among ICVD patients, the incident of CAS had no gender difference.
