后循环急性多发脑梗死36例临床分析

目的:研究后循环多发脑梗死病因、发病机制、影像学特点、临床表现。方法:收集2007年5月~2009年8月大连三院神经内科住院的后循环多发脑梗死患者的临床资料,分析其病因、影像学特点、临床表现。结果:病因为动脉粥样硬化、血管狭窄者29例(81%),其中高血压23例、糖尿病18例、高脂血症25例、吸烟15例、饮酒13例、病因为心脏病者7例,其中房颤5例、陈旧性心肌梗死2例、临床表现按症状和体征发生频率依次为眩晕19例、肢体瘫痪17例(偏瘫13例,四肢瘫痪4例)、构音不清16例、偏盲12例、共济失调8例、颅神经麻痹7例、意识障碍3例;按不同责任病变血管分类,以大脑后动脉病变最常见(46%),其次为基底动脉(31%),椎动脉病变者(23%)。结论:动脉粥样硬化是急性后循环脑梗死的最常见原因,动脉粥样硬化至动脉栓塞是其主要发病机制。眩晕、偏瘫、构音障碍是其常见临床表现,血管受累以大脑后动脉最常见,后循环多发脑梗死病灶大小相对较小,临床转归较好。
