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 analyze the clinical characteristics of patients with transient ischemic attack (TIA) and the incidence of cerebral artery stenosis or occlusion by means of digital subtraction angiography (DSA). Methods: A total of 65 patients with transient ischemic attack admitted to Department of Neurology, West China Hospital, Sichuan University from January 2003 to August 2007 were enrolled. The patient’s clinical features, arterial disease? Stenosis analysis. Results: Among 65 TIA patients, 38 cases (58.5%) were found vascular lesions, including 14 cases (21.5%) with unilateral involvement and 24 cases (36.9%) with multiple lesions. The moderate and severe occlusive vascular stenosis was more common , And more occurred in the extracranial segment. Conclusion: DSA can clarify the degree of vascular atherosclerosis and stenosis in patients with TIA, which plays an important role in guiding the treatment.
