Objective: To discuss the vascular factors in 26 cases of young patients with ischemic stroke by analyzing their digital subtraction angiography ( DSA ) results. Method: From May 2007 to May 2009 according to diagnostic standards for TIA revised by the Fourth National Conference on cerebrovascular ( 1995 ) , we selected a total of 26 patients with TIA ( mean age 39 years ),and analyzed their DSA images. Result: Through the DSA images in 26 cases,we found vascular problems in 20 cases. Among them 4 cases ( 20% ) had congenital vascular lesions, 16 cases ( 80% ) had stenosis occlusions. In the latter, 37. 5% involved the extracranial blood vessels and 62.5% involved the intracranial blood vessels. Visible atherosclerotic plaques rupture was one of the main reasons that occurred TIA in young people. Prevention of atherosclerosis will be a major direction for reducing youth stroke. Conclusion: The vascular lesions are the foundations of ischemic stroke. DSA can help us to understand the blood vessels status in young people with TIA. Therefore, this examination can play a vital role in stroke prevention.%目的:本文旨在通过对26例青年短暂性脑缺血发作(TIA)患者的DSA分析来探讨血管因素在年青人脑血管病中发生的影响.方法:自2007年5月至2009年5月根据1995年全国第四届脑血管会议修订的标准选出26例TIA患者(平均年龄39岁),分析其DSA影像.结果:在26例患者DSA影像中,发现问题的有20例,其中先天性血管病变有4例(20%),狭窄或闭塞的有16例(80%).后者中累及颅外血管12支(37.5%),颅内血管20支(62.5%).可见动脉粥样硬化,斑块脱落也是年轻人TIA发生的主要原因之一.预防动脉粥样硬化或许将是降低青年卒中发生的一个主要方向.结论:血管病变是缺血性疾病的发生基础,DSA能很好的帮助我们了解TIA中年轻人的血管情况,对预防卒中的发生能起到至关重要的作用.
