摘　　要：目的:借助全脑血管造影(DSA)和ABCD2工具观察短暂性脑缺血发作(TIA)临床表现与血管病变之间的关系,探讨TIA发生卒中风险的原因。方法:128例TIA患者入院时根据ABCD2评分分组,高风险组58例,中低风险组70例,观察血管狭窄的程度和分布,血流代偿,溃疡斑块存在的情况。结果:高风险组狭窄≥70%的发生率为67.2%,高于中低风险组(51.4%)(χ2=6.242,P<0.05);高风险组溃疡斑块的发生率为51.7%,高于中低风险组(38.6%)(χ2=6.027,P<0.05),中低风险组血流代偿的发生率为77.1%,高于高风险组(65.5%)(χ2=5.913,P<0.05)。结论:TIA高风险的可能原因为血管狭窄造成的低灌注和溃疡斑块微栓子脱落导致的栓塞,有血流代偿可能起了到缓解病情的作用。Objective： To observe the relationship between the clinical manifestation and cerebral artery disease by brain digital subtraction angiography （DSA） and ABCD2 score, and investigate the risk factor of cerebral infarction induced by transient ischemie attacks. Methods： 128 patients with TIA were divided into two groups： a higher subsequent stroke risk group, a middle and lower subsequent stroke risk group by ABCD2 score. The cerebral artery stenosis, collateral circulation on the occurrence, unstable plaque were studied. Results： There were significant differences between the two groups, in incidence rate of ≥70% stricture （67.2% vs 51.4%, χ2=6.242, P〈0.05）, collateral circulation on the occurrence （65.5% vs 77.1%, χ2=5.913, P〈0.05）, unstable plaque （51.7% vs 38.6%, χ2=6.027, P〈0.05）. Conclusion： The cerebral artery stenosis and unstable plaque correlated with TIA are high risk factors; collateral circulation on the occurrence can effectively alleviate the clinical symptoms.
