短暂性脑缺血发作患者颅内外动脉狭窄分布特征的分析

Study of intracranial and extracranial arterial stenosis in patients with transient ischemic attack

目的探讨短暂性脑缺血发作(TIA)患者颅内外动脉狭窄的分布特征。方法对178例TIA患者进行全脑血管造影(DSA)检查,分析脑动脉颅内动脉狭窄、颅外动脉狭窄的发生率及其分布情况。结果在178例TIA患者中,124例(69.66%)存在脑动脉狭窄或闭塞,其中前循环动脉狭窄或闭塞50例(40.32%)、后循环为44例(35.48%)、前后循环均有病变为30例(24.19%);颅内动脉狭窄或闭塞29例(23.39%),颅外动脉为72例(58.06%),颅内、外动脉均有病变为23例(18.55%)。发现狭窄血管共237支,其中单支血管病变58例、多支血管病变66例。颅外血管狭窄以颈内动脉颅外段最多为81支,颅内血管狭窄以椎动脉颅内段最多为41支。结论 TIA患者常伴有脑血管狭窄,准确地评价患者脑动脉狭窄的分布情况及其程度,为临床提供了诊治依据。

Objective To investigate the characterisitics of intracranial and extracranial arterial stenosis in patients with transient ischemic attack .Methods 178 patients with transient ischemic attack were detected by DSA in order to analyze the distribution and the occurrence of intra-extracranial vascular .Results The 178 cases of transient ischemic attack, the rate of intra-extracranial vascular stenosis was（69.66%）（124 cases）.40.32%（50 cases） was in anterior circulation and 35.48%（44 cases） was in the posterior circulation and 24.19%（30 cases） was in the anterior-posterior circulation.233.9%（ 29 cases）was of intracranial stenosis, 58.06%（72 cases）was of＆nbsp;extracranial stenosis and 18.55%（ 23 cases） was both.As for incidence of single or dual stenosis among 237 vessels with arteriostenosis , single stenosis amounted to 58cases and dual to 66 cases.Extracranial stenosis occurred most in extracranial part of internal carotid artery.Intracranial stenosis more occurred in intracranial vertebral artery . Conclusion DSA can be accurate evaluation the distribution and degree of cranial vessels stenosis .So as to provide basement for the clinical treatment .
