目的:探讨数字减影血管造影、彩色多普勒超声和经颅多普勒超声对短暂性脑缺血发作的诊断价值.方法:96例短暂性脑缺血发作患者分别行数字减影血管造影、彩色多普勒超声及经颅多普勒检查进行分析.结果:数字减影血管造影显示78例短暂性脑缺血患者存在颅内-外动脉狭窄(81.2%),颅内动脉狭窄高于颅外动脉(57.5%、42.4%).颅外动脉狭窄以颈内动脉颅外段最多,占45.2%;颅内动脉狭窄以大脑中动脉(MCA)最多,占41.2%.75例颈动脉超声检查异常(75/96,78.1%).83例TCD检查异常(83/96,86.4%).结论:数字减影血管造影、彩色多普勒超声及经颅多普勒超声联合应用可对短暂性脑缺血发作的病因作出客观评价及指导治疗.%Objective-To evaluate the diagnostie values of DSA, ultrasonography and TCD in carotid terri tory TIA. Methods: 96 patients with TIA swere examined by DSA, ultrasonography and TCD. Results: DSA showed 78 cases(81.2 %)were found artery stenosis in 96 cases with TIA. In general, there were more patientsith intracranial stenosis than extraeranial stenosiS(57.5 %, 42.4 % ). Extraeranial artery stenosiswere most common in Extraeranial artery stenosiswere most common in the extraeranial segments of internal carotid artery (45.2 %), and the middle cerebral arteries were most common in the intracranial counterparts(41.2 %). Abnormalities of intraeranial arteries were detected by TCD in 83 cases (83/96, 86.4%)and abnormalities of carotid arteries were detected by ultrasonography in 75 cases(75/96, 78.1% ). Conclusion: DSA, ultrasonography and TCD are useful in the evaluation of etiological factors of Tlhs.
