老年患者急性脑梗死与颈动脉粥样硬化的关系探讨

目的 分析老年人颈动脉粥样硬化（CAS）与脑梗死的关系。方法对106例老年急性脑梗死患者（ACI组，年龄〉65岁）和102例无缺血性脑血管病的对照组进行颈动脉超声检查，评价粥样硬化斑块的位置、稳定性、造成的颈动脉狭窄情况，并分析三者与脑梗死的关系。结果ACI组颈动脉斑块检出率为87．02％，显著高于对照组检出率15．02％（P〈0．005）。ACI组中，中型及重型脑梗死患者的不稳定斑块检出率（51／86）显著高于轻型脑梗死患者（5／20）（P〈0．025）。结论颈动脉粥样硬化是脑梗死的独立危险因素。

The relation between acute cerebral infarction of elderly patients and carotid atherosclerosis

Objective To investigate the association between carotid atherosclerosis and acute cerebral infarction(ACI) of elderly patients. Methods 106 patients with ACI were examined by ultrasound and compared with 102 controls. the location and stability of the carotid atheromatous plaques , the stricture they caused, the relations with ACI were evaluated. Results Carotid plaques were found in ACI group and the prevalence was 83.02%, compared with 15.02% of the control group. There was obvious difference between the two groups (P<0.005). The unstable plaques were more common in moderate and severe cases than in mild cases (P<0.025). Conclusions Carotid atherosclerosis is an isolated factor of ACI.
