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。
Objective To investigate the clinical features and pathogenesis of watershed cerebral infarction and its relationship with macrovascular stenosis. Methods Based on the results of cerebrovascular angiography, combined with magnetic resonance data for retrospective analysis. Results There was no significant difference in the clinical features between the three groups of watershed cerebral infarcts. There were severe vascular stenosis in 8/10 celiac degenerative cerebral infarction, severe vascular stenosis in 29/42 subcapsular watershed cerebral infarction, and severe severity in 6/6 mixed watershed cerebral infarction Stenosis. Conclusion Watershed cerebral infarction is closely related to cerebrovascular stenosis. Hypotension is associated with its pathogenesis.
