不同部位缺血性脑卒中患者颈动脉超声特点的研究

The ultrasound character of carotid artery in acute ischemic stroke patients with different subtype

目的探讨不同亚型的缺血性脑卒中患者的颅外段颈动脉硬化病变的发生状况及病变程度,为缺血性脑卒中的防治提供依据。方法收集急性缺血性脑卒中患者351例,按头颅CT或MRI结果分为皮质型(CI)、皮质下型(SCI)、椎基底动脉型(VBCI)3个亚型,同时应用彩色多普勒超声对颅外段颈动脉病变进行量化评估,分析各型之间不同颅外段颈动脉病变的发生状况及病变程度的差异。结果皮质型脑梗死颈动脉狭窄发生率为75.9%,高于其他组,且差异显著(P<0.05),皮质型脑梗死颈动脉狭窄>50%者为25.3%,高于其他组,且差异显著(P<0.05)。结论在缺血性脑卒中各亚型之间颅外段颈动脉硬化病变的发生状况及病变程度存在差异,其中以CI的病变最明显,其次为VBCI,SCI最低。

Objective To study angiographic characters of extracranial carotid atherosclerosis in acute ischemic stroke patients. Methods Based on clinical information, we separated 351 ischemic stroke into three subgroups： cortical infarction （CI）, subcortical infarction （SCI） and vertebrobasilar artery infarction （VBCI）. We assessed the extent and severity of extracranical carotid artery atherosclerosis in different Subtype of ischemic stroke using color Doppler ultrasound. Results The prevalence of carotid plague in patients with cortical farction was 75.9%, which was higher than other subtypes （P〈0. 05）. Carotid artery stenosis larger than 50% in patients with. cortical infarction was 25.3%, which was higher than other locations subtypes （P〈 0. 05）. Conclusions The angiographic distribution of extracranial carotid atherosclerosis varies in acute ischemic stroke patients. In cortical infarction it is more prominent than other subtypes.
