大脑中动脉严重狭窄或闭塞卒中类型分析

The analysis of stroke pattern in patients with severe stenosis or occlusion of middle cerebral artery disease

目的探讨大脑中动脉严重狭窄或闭塞患者卒中类型特点及其发病机制。方法经TCD确诊的大脑中动脉狭窄或闭塞患者,依据头部CT和(或)MRI所示梗死灶进行卒中分型。结果169例大脑中动脉严重狭窄或闭塞患者,卒中类型各亚型以腔隙性脑梗死(LI)最为常见,占38.46%,其次为分水岭梗死(WI)占19.23%。流域性脑梗死、弥散性多发点状脑梗死、半卵园中心梗死与MCA严重狭窄或闭塞程度有关。结论大脑中动脉严重狭窄或闭塞患者卒中类型以腔隙型脑梗死、分水岭梗死为主。卒中类型多种多样,血管检查应该作为缺血性脑血管病的常规检查。

Objective To investigate the characteristics of stroke patterns in patients with severe stenosis or occlusion of MCA disease and to understand further the pathogenesis of stroke. Methods 169 patients with severe stenosis or occlusion of MCA disease performed CT and （or） MRI. Separate these patiens into stroke subpattern aecording to the lesions on CT and（or） MRI. Results It showed that the oeeuranee of stroke patterns is LI with 38. 46%0 ,WI with 19.23%0. TI ,MSSI and SI are relative with the existence of severe stenosis or occlusion of MCA. Conclusion The main stroke subpattern is LI. Various subpattern could present,so vascular examination should be the routine of isehemie vascular disease.
