摘要
目的探讨短暂性脑缺血发作(TIA)与颅内外血管狭窄的关系。方法对130例TIA患者的CT血管成像(CTA)进行分析,观察TIA患者颅内外段血管有无狭窄及TIA发作次数与狭窄数量关系。结果 130例TIA中有血管狭窄94例(占72.3%)。颈内动脉系统TIA患者80例中有血管狭窄者55例(占68.75%),颈内动脉颅外段狭窄30例(占39.5%),颅内段狭窄16例(占21.1%),大脑中动脉狭窄26例(占34.2%),大脑前动脉狭窄14例(占18.4%)。椎基底动脉系统TIA患者50例,有血管狭窄者39例(占78%),椎动脉狭窄23例(占46%),基底动脉狭窄9例(占18%),大脑后动脉狭窄18例(占36%)。频发TIA 44例,其中有2支以上血管狭窄25例(56.82%),频发组TIA多支血管狭窄数量高于非频发组TIA。结论短暂性脑缺血发作常伴有脑血管狭窄,颈内动脉系统以颈内动脉颅外段狭窄为主,椎基底动脉系统以椎动脉狭窄多见,频发TIA常见2支以上血管狭窄。
Objective To study the relationship between intracranial and extracranial arterial stenosis and transient ischemic attack（TIA）.Methods The results of computed tomography angiography（CTA）of 130 patients with transient ischemic attack related to intracranial and extracranial arterial stenosis were retrospectively analyzed and compared with patients with frequent transient ischemic attack.Results Intracranial or extracranial arterial stenosis were revealed in 94 patients（72.3%）.Of 80 cases of TIA patients with internal carotid artery system,arterial stenosis were 55 cases（68.75%）,extracranial internal carotid artery stenosis were 30 cases（39.5%）,intracranial stenosis were 16 cases（21.1%）,MCA stenosis were 26 cases（34.2%）,the anterior cerebral artery stenosis were 14 cases（18.4%）.Of 50 cases TIA patients with vertebrobasilar arterial systems,artery stenosis were 39 cases（78%）,vertebral artery stenosis were 23 cases（46%）,basal artery stenosis were 9 cases（18%）,posterior cerebral artery stenosis were 18 cases（36%）.Of 44 patients with frequent transient ischemic attack,above 2 lesions were 25 cases（56.82%）.There was significant difference between frequent transient ischemic attack and infrequent transient ischemic attack in artery stenosis quantity.Conclusion TIA patients usually have stenosis of cerebral artery.In carotid artery system,the stenosis mainly laid extracranial internal carotid artery.In verterbrobasilar artery systems,the vertebral artery stenosis is most.The frequent TIA patients usually have arterial stenosis above two lesions.
