摘要 目的:研究内侧分水岭脑梗死的临床表现、发病机制和弥散加权成像(DWI)特点。方法:自2005年2月至2007年12月,对入住我院的中风患者,经头颅MRI检查(常规MRI+DWI)证实为皮层下梗死的患者,根据内侧分水岭梗死的影像学模版分类为融合型内侧分水岭梗死(CIWI)和部分型内侧分水岭梗死(PIWI),并对脑血管病的危险因素、临床表现及神经影像学特征进行比较。结果:18例患者符合内侧分水岭脑梗死的诊断标准,其中CIWI5例,PIWI13例。7例有颈动脉狭窄或者闭塞,其中PIWI5例,CIWI2例,差异无统计学意义(P>0.05)。PIWI吸烟4例,CIWI吸烟3例。结论:内侧分水岭区脑梗死颈内动脉狭窄的发生率高,心脏病发病率高。CIWI表现为侧脑室旁内分水岭区大块融合的病灶,而PIWI表现为侧脑室旁内分水岭区小块不连续病灶,多发PIWI可表现呈串珠样。
