摘要
目的探讨颈动脉系统短暂性脑缺血发作(TIA)与颅内外动脉狭窄的关系,评价数字减影血管造影(DSA)在颈动脉系统TIA中的诊断价值。方法对70例颈动脉系统TIA患者进行DSA检查,观察血管病变的性质,判断责任动脉。结果 70例患者中检出血管狭窄或闭塞59例(84.3%),其中症状相关侧血管狭窄或闭塞51例,症状相关侧对侧8例;颅内动脉狭窄发生率为86.9%(73/84),颅外动脉狭窄发生率为13.1%(11/84);56例(94.9%)可以判断责任动脉。结论颅内外动脉狭窄是颈动脉系统TIA的重要原因,DSA可以明确TIA患者血管狭窄的部位、程度、性质。
Objective To study the relationship between transient ischemic attacks(TIA) on carotid artery system and intracranial or extracranial artery stenosis.The diagnosis value of TIA on carotid artery system was evaluated on DSA.Methods 70 patients with TIA on carotid artery system were examined.The characteristics of vascular lesions and identified guilty arteres were observed by DSA.Results 59 patients(84.3%) with artery stenosis or occlusion were founded.Among them,51 patients had clinically relevant artery stenosis or occlusion and 8 patients had contralateral lesions.The rate of intracranial artery stenosis was 86.9%(73/84) and extracranial artery stenosis was 13.1%(11/84).The guilty arteres in 56 cases(94.9%) were identified.Conclusion Intracranial or extracranial artery stenosis is the important factor of TIA on carotid artery system.DSA can define the location,degree and characteristic of artery stenosis.
