摘要
目的探讨短暂性脑缺血发作(TIA)与脑动脉狭窄的关系。方法从南京卒中注册数据库中,选择经CT、MRI确诊,并行数字减影血管造影(DSA)检查的53例TIA患者临床资料,分析脑动脉狭窄的发生情况。结果14例患者脑血管未见异常,39例存在脑动脉狭窄或闭塞,其中单纯颅外动脉狭窄13例,单纯颅内动脉狭窄11例,颅内、外动脉合并狭窄15例。32例前循环TIA患者中发生前循环动脉狭窄22例(68.8%);21例后循环TIA患者中发生后循环动脉狭窄8例(38.1%),两组狭窄发生率差异有显著意义(P<0.05)。结论TIA患者的颅外动脉狭窄发生率高于颅内动脉。前、后循环的脑动脉狭窄与其TIA临床表现的符合率,前循环TIA者较后循环TIA者为高。
Objective Tn investigate the correlation between cerebral artery stenosis and transient isehemic attack （TIA）. Methods 53 TIA patients from Nanjing Stroke Registry were studied. The oceurrence of cerebral artery stenosis in patients was assessed. Results Cerebral artery stenosis or occlusion were found in 39 patients. Among them 13 cases had extracranial artery stenosis. 11 patients had intracranial artery stenosis and 15 patients had both extracranial and intracranial artery stenosis. 14 patients showed normal image. 22 out of 32 patients with anterior circulation TIA had anterior circulation stenosis （68.8%） . 8 out of 21 patients with posterior circulation TIA had posterior circulation stenosis （ 38.1% ） . The occurrence of stenosis was significant difference between two groups （ P 〈 0. 05 ） . Conclusion The oeeurrenee of extracranial artery stenosis is more frequent than that of intraeranial artery in TIA patients. The coincidence between clinical manifestations and the same type cerebral artery stenosis is more in anterior circulation TIA than that in posterior circulation TIA.
