摘　　要：[目的]研究短暂性脑缺血发作的流行病学及神经影像学特征,为临床及早判断病情和及时有针对性的干预治疗提供理论依据。[方法]分析360例TIA患者一般资料(包括性别、年龄等)、影像学检查特点(包括头颅CT、头颅MRI及颈部血管彩色多普勒超声)。[结果]360例TIA临床表现持续时间在10min以内的146例(40.6);125例频繁发作患者中,进展为缺血性卒中者16例(12.8);235例非频繁发作患者中,进展为缺血性卒中者19例(8.1),两组比较差异有统计学意义(P﹤0.05);供血区由ICA系统支配者234例(65),VBA系统支配者126例(35);临床表现出现的频率最高的为:肢体瘫痪(64.3);抗血小板治疗者236例(65.6);302例患者(83.9)在出院前7～10d内症状停止发作,29例(8.1)患者进展为完全性卒中;349例患者有脑CT检查结果,CT检查率96.9,108例患者有头颅MRI检查,MRI检查率30。[结论]TIA症状持续时间多为10min以内,频繁发作者进展为缺血性卒中远高于非频繁发作者,以ICA系统多见,临床最常见症状为肢体瘫痪,阿司匹林应用率最高,多数患者停止发作,但是仍有患者进展为完全性卒中,TIA的抗血小板治疗有效。[Objective]To study the epidemiology and neuroimaging features of transient ischemic attack,to provide a theoretical basis for diagnosis anf intervention treatment.[Methods]Analyzed the general information（including sex and age,etc.）,imaging characteristics（including head CT,MRI,carotid doppluer,etc.）of the patients with TIA.[Results]Duration time of patients within 10 minutes was 40.6%.65% of 360 patients were internal carotid artery（ICA）TIA,and 35% were vertebrobasilar artery（VBA）TIA.The percentage of CT scan was 96.9%,while MRI was 30%.[Conclusion]Duration time of TIA lasts within 10 minutes.There is a significant difference between the attack frequently and unfrequently.The most common symptom is limb paralysis.Antiplatelet trreatment is more effective in treatment of TIA.
