目的探讨颈动脉狭窄与脑梗死的关系。方法采用多普勒超声对72例脑梗死患者和70例无脑卒中病史的对照组患者的颈动脉进行检测,比较脑梗死组与对照组颈动脉形态的差异。结果72例脑梗死患者中有65例患者检出动脉硬化斑块96个,颈动脉狭窄程度轻度11例,中度35例,重度19例;70例对照组有12例患者检出动脉硬化斑块17个,颈动脉狭窄程度轻度8例,中度3例,重度1例。结论颈动脉B超能显示颈动脉粥样斑块和狭窄程度,对早期干预和脑梗死的预防有重要意义。 Objective To investigate the relationship between carotid artery stenosis and cerebral infarction. Methods The carotid arteries of 72 patients with cerebral infarction and 70 patients without history of stroke were examined by Doppler echocardiography. The carotid artery morphology was compared between cerebral infarction group and control group. Results Of the 72 patients with cerebral infarction, 65 patients had atherosclerotic plaques detected in 96, mild carotid stenosis in 11, moderate in 35, and severe in 19; 70 of the control group, 12 patients were detected atherosclerosis 17 plaques, mild carotid stenosis in 8 cases, moderate in 3 cases and severe in 1 case. Conclusion Carotid artery B-carotid artery plaque and stenosis can show the degree of prevention of early intervention and cerebral infarction is important.
