70例进展性脑梗死患者颈动脉斑块的超声分析

Ultrasonic analysis of carotid plaques in 70 patients with progressive cerebral infarction

目的探讨进展性脑梗死患者颈动脉斑块的超声特征表现。方法应用彩超观察70例进展性脑梗死患者颈总动脉和颈内动脉斑块形成情况以及斑块的部位、大小、形态、管腔狭窄率。结果 70例患者中59例患者肢体障碍对侧颈总动脉及颈内动脉有斑块形成。其中颈总动脉21例,颈内动脉11例,两者均有斑块者27例。斑块可分为规则型、不规则型和溃疡型。伴有50%以上狭窄者45例。结论彩超能够清晰显示进展性脑梗死患者颈动脉斑块形成情况,为其病因诊断提供了可靠的影像学资料。

Objective To investigate the ultrasonic characteristics of carotid plaques in patients with progressive cerebral infarction.Methods The site,size,shape,stenosis rate of plaques in common carotid artery and internal carotid artery were observed in 70 patients with progressive cerebral infarction by color Doppler ultrasound.Results Among the 70 patients,59 showed plaques in the common carotid artery and internal carotid artery opposite to the side of physical disability,of which 21 were in common carotid artery,11 were in internal carotid artery,and 27 were in both common carotid artery and internal carotid artery.The plaques can be divided into regular type,irregular type and ulcer type.Forty-five patients had 50% stenosis or more.Conclusion Color Doppler ultrasound can clearly display the condition of carotid artery plaque in patients with progressive cerebral infarction,which provides reliable imaging data for etiological diagnosis.
