摘　　要：目的探讨分水岭脑梗死(CWI)的临床及影像学特征。方法选择经颅脑MRI证实为CWI患者67例(CWI组),另选无CWI的67例多发性腔隙性脑梗死患者为对照组。比较二组、CWI分型、64排螺旋计算机体层扫描血管成像(CTA)结果及美国卫生研究院脑卒中量表(NIHSS)评分。结果二组患者均行CTA检查:CWI组颅内血管狭窄或闭塞41例(61.2%),对照组17例(25.4%)差异有显著性(P<0.01);其中CWI组多支血管病变22例(53.7%),对照组5例(29.4%),差异有显著性(P<0.05)。CWI组中CTA检查示颅内血管狭窄或闭塞:皮质型CWI9例(42.9%),皮质下型25例(71.4%),混合型7例(70%),差异有显著性(P<0.05)。二组NIHSS评分差异无显著性。结论 CWI的发生与颅内血管狭窄或闭塞密切相关,尤其是皮质下型和混合型CWI。【Objective】 To explore the clinical feature and imaging of cerebral watershed infarction（CWI）.【Methods】 A retrospective study of models with the cerebral watershed infarction and the general cerebral infarction in our hospital was performed.【Results】 Among 67 cases of the CWI group,41 cases（61.2%） were discovered with blood vessel dysfunction by computerized tomography angiography（CTA）.The incidence rates of blood vessel dysfunction in these cases were significantly higher than those in the control group（25.4%）.The subcortex type（71.4%） and mixed type（70.0%） in sub-CWI group were significantly higher than cortex type（42.9%）（P 0.05）.【Conclusions】 The occurrence of CWI,especially the subcortex and mixed type,is tightly related to the stenosis or occlusion of large intracranial vessel.
