摘    要:目的探讨颈内动脉系统频发短暂性脑缺血发作(TIA)颈内动脉系统血管狭窄率及特点。方法分析43例颈内动脉系统频发TIA患者的脑CT血管成像(CTA),并与非频发TIA进行对比。结果43例颈内动脉系统频发TIA患者中,有15例(35%)表现为颈内动脉系统颅内动脉狭窄,10例(23%)颅外动脉狭窄,4例(9%)颅内动脉、颅外动脉均有狭窄,14例(33%)无狭窄,狭窄率为67%。轻度、中度、重度狭窄患者分别为7例(16%)、9例(21%)、13例(30%)。33例颈内动脉系统非频发TIA颈内动脉系统血管狭窄率为79%,两组之间无显著性差异(P=0.273)。结论67%的颈内动脉系统频发TIA患者存在颈内动脉系统血管狭窄,但与非频发TIA患者颈内动脉系统狭窄比较无统计学差异。

关 键 词:短暂性脑缺血发作  颈内动脉  CT血管成像

Abstract:Objective To investigate the characteristic and rate of vascular stenosis of frequent transient isehemicattaek related to internal carotid artery. Methods Results of computed tomography angiography (CTA) of 43 patients with frequent transient isehemic attack related to internal carotid artery were retrospectively analyzed and compared with patients with infrequent transient ischemic attack. Results Stenosis of intracranial artery, extraeranialartery, both intracranial and extracranial artery existed in 15 (35%), 10 (23%), 4 (9%) patients, respectively. The rate of stenosis was 67%. Patients with mild stenosis, moderate stenosis, severe stenosis were 7 (16%), 9(21% ), 13(30% ), respectively. The stenosis rate of internal carotid artery system of 33 patients with infrequent transient isehemie attack was 79%. There was no significant difference between these two groups (P = 0. 273 ). Conclusion Stenosis existed in 67% patients with frequent transient ischemie attack related to internal carotid artery, but there was no statistical difference compared with infrequent transient isehemic attack.
Keywords:Transient ischemie attack  Internal carotid artery  Computed tomography angiography
