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 investigate the occurrence and severity of extracranial carotid atherosclerotic lesions in patients with different subtypes of ischemic stroke and to provide evidence for the prevention and treatment of ischemic stroke. Methods A total of 351 patients with acute ischemic stroke were enrolled and divided into three subtypes: cortical (CI), subcortical (SCI) and vertebrobasilar (VBCI) by skull CT or MRI. At the same time, Le son ultrasonography extracranial carotid lesions quantitative assessment, analysis of different types of different extracranial carotid lesions and the occurrence of lesions between the degree of difference. Results The incidence of carotid artery stenosis was 75.9% in cortical cerebral infarction group, which was significantly higher than that in other groups (P <0.05). The cortical cerebral infarction with carotid artery stenosis> 50% was 25.3%, higher than other groups Significant (P <0.05). Conclusion There are differences in the occurrence and severity of extracranial carotid atherosclerotic lesions among the subtypes of ischemic stroke. Among them, the lesions of CI are the most obvious, followed by VBCI and SCI.
