全脑DSA在缺血性脑血管病中的诊断价值

The application of global DSA in the diagnosis of ischemic cerebrovascular diseases

目的探讨全脑DSA在缺血性脑血管疾病中的诊断价值,为临床应用提供依据。方法选取2012-01—2014-09来我院就诊的缺血性脑血管疾病患者198例,均采用全脑DSA对其进行血管造影,对比分析其血管异常情况及狭窄程度。结果 198例患者中,8例脑血管正常,190例异常（120例颅内血管异常,70例颅外异常）;对血管狭窄程度来说,其中有50例〈50%,91例达50%~70%,49例〉70%,且颈内动脉颅内段狭窄较外段程度严重（P〈0.05）。结论全脑DSA能够准确有效的对缺血性脑血管疾病进行诊断,为临床治疗提供理论依据,具有重要的应用价值。

Objective To evaluate the diagnostic value of the whole brain DSA in ischemic cerebrovascular diseases in or‐der to provide the evidence for clinical application .Methods We selected 198 cases with ischemic cerebrovascular diseases re‐ceiving global DSA in our hospital from September 2012 to September 2014 ,then comparatively analyzed the condition of vascu‐lar abnormality and vascular stenosis .Results In all of 198 cases ,cerebrovascular normality was in 8 cases ,abnormality in 190 cases （120 cases occurring in intracranial vascular and 70 cases in extracranial vascular ） .As to the degree of vascular stenosis , 50 cases had the stenosis degree of 〈50% ,91 cases reached the degree of 50%‐70% ,and 49 cases even owned the severe de‐gree of ＆gt;70% .In addition ,the stenosis in intracranial part of internal carotid artery was significantly severer than that in ex‐tracranial part （P〈0 .05） .Conclusion The whole brain DSA can accurately and efficiently diagnose ischemic cerebrovascular diseases and can provide theoretical evidence for the clinical treatment ,which has important application value .
