摘要
目的分析分水岭脑梗死(CWI)患者的数字减影血管造影(DSA)血管影像表现,探讨其发生的相关高危因素。方法回顾64例经MRI诊断的CWI患者的DSA结果,单因素分析和多因素Logistic回归分析CWI的相关高危因素。结果 DSA发现有27例患者有明显血管狭窄,15例患者有明显血管迂曲,6例患者血管狭窄合并迂曲。Logistic回归分析显示高龄、高血压、男性、吸烟和血压谷峰比值增大是CWI发生的独立危险因素。结论 DSA检查发现CWI患者大部分存在血管病变。高龄、高血压、男性、吸烟和血压谷峰比值增大是CWI发生的独立危险因素,治疗CWI患者应积极进行血管评估和控制高危因素,进行针对性治疗。
Objective To study the digital subtraction angiography(DSA) images in patients with cerebral watershed infarction(CWI) and the risk factors of the development of CWI.Methods The DSA image results of 64 patients with CWI confirmed by MRI were retrospectively studied.The risk factors of CWI were evaluated by univariate analysis and multivariate logistic regression analysis.Results Of the 64 patients,27 showed cerebrovascular stenosis,15 showed cerebrovascular dolichoectasia,and 6 showed cerebrovascular stenosis and cerebrovascular dolichoectasia.Multivariate logistic regression analysis showed age(elder),hypertension,male,smoking,and increased trough/peak ratio were the independent risk factors for CWI.Conclusions Most of CWI patients present with cerebrovascular disorders by DSA.Targeted prevention and treatment by controlling risk factors,age(elder),hypertension,male,smoking and increased trough/peak ratio,may be important to reduce the occurrence of CWI.
