摘要
目的:以数字减影血管造影(DSA)为手段,分析短暂性脑缺血发作(TIA)患者临床特点及脑供血动脉狭窄或闭塞的发生率。方法:对2003年1月至2007年8月期间四川大学华西医院神经内科收治且行DSA检查的短暂性缺血发作患者65例进行研究。对患者临床特点,动脉病变情况?狭窄程度进行分析。结果:65例TIA患者中发现血管病变有38例(58.5%),其中单侧受累14例(21.5%),多处受累24例(36.9%),中度及重度,闭塞的血管狭窄多见,且多发生在颅外段。结论:DSA可以明确TIA病患者中血管动脉粥样硬化,狭窄程度,这对指导治疗起重要作用。
Objective: To evaluate the location of arterial lesions and clinic characteristics in a population of West China with first-ever transient ischemic attack.Methods: The study was conducted on 65 patients with TIA who performed DSA in our department from 2003 to 2007.Vascular findings were classified in categories according to the type of lesion,the degree of the stenosis and the location in the carotid artery territory or vertebrobasilar artery territory.Results: Thirty-eight(58.4%) patients had artery lesions,and twenty-four out of thirty-eight had more than one site.Moderate and severe and occlusion occurred more frequently,and most did in extracranial arteries.Conclusion: Digital subtraction angiography helps to identify the vascular etiology of TIA and provides the instruction of therapeutic regimen.
