目的观察短暂性脑缺血发作(TIA)患者的脑血管造影特点及脑动脉狭窄分布情况。方法回顾性分析本院102例短暂性脑缺血发作患者住院期间行数字减影全脑血管造影(DSA)的影像学特点及脑动脉狭窄分布情况。结果 102例患者中存在脑动脉狭窄或闭塞的85例,占83.3%;仅前循环受累占52例,占61.1%;仅后循环受累占18例,占21.1%;前后循环均受累15例,占17.6%。结论 TIA的主要原因之一是脑血管狭窄,前循环病变较后循环多,颅内病变较颅外多。
Objective To investigate the characteristics of cerebral angiography and the distribution of cerebral artery stenosis in patients with transient ischemic attack (TIA). Methods A retrospective analysis of 102 patients with transient ischemic attack in our hospital during hospital digital subtraction global cerebral angiography (DSA) imaging features and distribution of cerebral artery stenosis. Results There were 85 cases of cerebral artery stenosis or occlusion in 102 patients, accounting for 83.3%. Only the anterior circulation involved 52 cases (61.1%), the posterior circulation involved 18 (21.1%), and the anterior and posterior circulation involved 15 cases Accounting for 17.6%. Conclusion One of the main causes of TIA is cerebrovascular stenosis. More cycles of anterior circulation and more intracranial lesions occur than those of the extracranial.
