彩超联合血管造影对脑梗死患者颈动脉病变的临床观察

目的通过观察脑梗死患者颈动脉颅外段的病变,分析不同类型脑梗死的发病原因。方法对59例脑梗死患者进行颈动脉彩超筛查,并进行血管造影检查,对其颈动脉病变进行回顾性分析。结果 59例脑梗死患者均有颈动脉颅外段狭窄及斑块形成,其中分水岭脑梗死组中颈动脉狭窄50%～70%的比例明显高于腔隙性脑梗死组,而腔隙性脑梗死组中颈动脉狭窄〈50%的比例明显高于分水岭脑梗死组。分水岭脑梗死组中溃疡斑的比例明显高于腔隙性脑梗死组。结论颈动脉颅外段病变与脑梗死的发生存在一定的关系,其中分水岭脑梗死的病因复杂,可同时存在颈动脉颅外段动脉狭窄及不稳定斑块,而两者在发病中起到协同作用。

The clinical observation of cerebral infarction accompanying with abnormally extracranial carotid artery by carotid artery color doppler ultrasound and angiography

Objective To explore the clinical characteristics of different types of cerebral infarction by observing the extracranial carotid artery.Methods 59 cases were diagnosed as cerebral infarction were examed by carotid artery color doppler ultrasound and angiography.The vascular abnormality from the examination would be analysed retrospectively.Results There were extracranial carotid artery stenosis and plaque in all cases.Carotid artery stenosis(50%-70%) in the cases from cerebral watershed infarction group was significantly higher than that from lacunar cerebral infarction group and carotid artery stenosis(<50%) in the cases from lacunar cerebral infarction group was significantly higher than that from cerebral watershed infarction group.There were more ulcerated plaques in cerebral watershed infarction group than that in lacunar cerebral infarction group.Conclusion Extracranial carotid artery lesions is the major cause of cerebral infarction.Cerebral watershed infarction can be cause by extracranial carotid artery stenosis and unstable plaques at the same time.
