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。
Objective: To investigate the relationship between ischemic cerebrovascular disease (ICVD) and carotid atherosclerosis (CAS). Methods: 206 patients were divided into transient ischemic attack (TIA group) and cerebral infarction (CI group). The pathological changes of carotid artery were detected by color Doppler ultrasonography and were compared with healthy subjects (control group) For comparative analysis. Results: (1) The detection rate of CAS in CI group was higher than that in TIA group (P <0.05), and the detection rate of plaque was also higher than that in TIA group (P <0.05). The CAS detection rate in case group was significantly higher than that in control group P <0.01). (2) Case-group CAS detection rate and age-related, but no gender-related. Conclusions: (1) The detection rate of CAS in CI group is higher than that in TIA group, and mainly in hard spot. (2) The detection rate of CAS in ICVD patients increases with age but has no correlation with sex; (3) The use of ultrasound to detect carotid arteries is an effective method of finding CAS and its extent.
