Objective: To study the relationship between carotid atherosclerosis and cerebral infarction, and to estimate the effect of carotid atherosclerosis on cerebral infarction. Methods: 106 cases of patients who were proved acute cerebral infarction underwent color Doppler ultrasonography examinations, and 66 cases of normal group as control group. Results: The positive rate of the cerebral infarction patient group was 81.1％, there was a significant difference compared with the control group (42.4％) (ρ＜0.01). Conclusion: Carotid atherosclerosis is the dangerous factor for cerebral infarction. The early diagnosis and intervention is necessary.%目的:研究颈动脉粥样硬化与脑梗死关系,评价颈动脉粥样硬化在脑梗死发生及发展中的作用.方法:选取106例确诊的急性脑梗死患者行颈动脉彩超检查,并选取正常对照组66例行颈动脉彩超检查.结果:脑梗死患者组颈动脉彩超异常率为81.1%,与正常对照组(42.4%)比较,差异有统计学意义(P<0.01).结论:颈动脉粥样硬化是脑梗死的重要危险因素,尤其颈动脉严重狭窄伴软斑块形成是卒中高危状态,应早诊断、早干预.
