摘要：

目的探讨内侧分水岭梗死(IWI)的临床和影像学特点及与颈动脉系统病变的关系。方法选择DWI病灶符合内侧分水岭梗死的患者27例,将其分为融合型IWI(CIWI)及部分型IWI(PIWI)。行头部颈动脉MRA和(或)DSA进行血管评价,确定主要责任血管病变;于入院第1天及第7天测量NIHSS评分,确定病情;卒中后3个月采用修订的Rankin评分评价预后。结果27例IWI患者中14例为融合型,13例为部分型;22例(82%)有颈动脉系统严重狭窄或闭塞,其中CIWI12例,PIWI10例,差异无统计学意义(P>0.05)。CIWI患者ICA病变的发生比例高于PIWI患者(11/14,4/13),多表现为非腔隙综合征(10/14,4/13);PIWI患者MCA病变的发生比例高于CIWI患者(6/13,1/14),多表现为腔隙综合征(9/13,4/14),差异有统计学意义(P<0.05)。CIWI患者较PIWI患者7d内多见病程进展,且3个月预后差(5/14,0/13;P<0.05)。结论IWI与颈动脉系统病变存在比较确切的关系,CIWI和PIWI发病机制中受累的血管作用存在一定差异。
