摘要
目的探讨颈动脉斑块和狭窄与脑梗死的关系。方法采用彩色多普勒超声(US)对32例脑梗死患者(梗死组)和32例无脑卒中病史(对照组)患者颈动脉进行检测,比较脑梗死组与对照组颈动脉形态的差异。结果脑梗死组患者中有30例(93.75%)患者检出动脉硬化斑块67处,颈动脉狭窄23例(71.88%),其中轻度狭窄3例(9.38%),中度狭窄12例(37.50%),重度狭窄及闭塞各4例(12.50%);对照组有12例(37.50%)患者检出动脉硬化斑块22处,颈动脉狭窄程度轻度2例(6.25%)。颈动脉狭窄和动脉硬化斑块两组比较差异均有统计学意义(P<0.01)。结论颈动脉狭窄可致缺血性卒中的危险性升高, US显示不规则、低回声斑块与脑梗死的发生有关,US对早期干预和脑梗死的预防有重要意义。
Objective To investigate the correlation of carotid arteriostenosis and atheromatous plaques with cerebral infarction. Methods Carotid artery was assessed using Doppler ultrasongraphy in 32 patients with cerebral infarction and in 32 patients without cerebral infarction, and the characteristics of carotid artery were compared between patients with or without cerebral infarction. Results Of 32 patients with cerebral infarction, sixty-seven atherematous plaques were detected in 30 patients（93.75%）, and the carotid arteriostenosis was found in 23 patients （71.88%）. The mild, moderate, severe carotid arteriostenosis and occlusion were found in 3 patients（9.38% ） ,12 patients（37. 50% ） and 4 patients （12. 50% ）, respectively. Of 32 patients without cerebral infarction, twenty-two atheromatous plaques were detected in 12 patients（37.50% ）. The mild carotid arteriostenosis was found in 2 patients （6. 25% ）, a significant difference （ P 〈 0. 01 ） in carotid arteriostenosis and atheromatous plaques between two groups. Conclusion Carotid arteriostenosis was participated in cerebral infarction. Doppler ultrasongraphy shows a relationship between atheromatous plaques and cerebral infarction. Using Doppler ultrasongraphy can show lesions of carotid arteriostenosis which is very important in preventing cerebral infarction.
