分水岭脑梗死临床分析

The study of the clinical features and analysis of cerebral border-zone infarction

目的探讨分水岭脑梗死的临床特点及发病因素,与大血管狭窄的关系。方法根据脑血管造影结果,结合磁共振资料做回顾性分析。结果3组分水岭脑梗死临床特征无显著性差异,8/10皮质型分水岭脑梗死有严重血管狭窄,29/42皮质下型分水岭脑梗死有严重血管狭窄,6/6混合分水岭脑梗死患者有严重血管狭窄。结论分水岭脑梗死与脑血管狭窄有密切关系,低血压与其发病相关。

Ob jective To study the clinical Features and the crisis factors. Methods We selected the patients with cortical border-zone infarction,internal border-zone infaretion and combined border-zone infarction.The digital subtraction angiography and MRI were studied. Results There were no difference in clinical characteristics among the three groups. 80% patients with cortical border-zone infarction had serious vascular stenosis,patients with internal border-zone infarction had serious vascular stenosis, patients with combined border-zone infarction had serious vascular stenosis. Conclusion The cerebral border-zone infarction is associated with serious vascular stenosis,hypotension is important crisis factor.
