摘要: 目的 比较AβCD2评分联合经颅多普勒(TCD)或脑血管造影检查(DSA)对短暂性脑缺血发作(TIA)后7d发生脑梗死的评估价值.方法 以2008年1月-2013年1月住院治疗的246例TIA患者为研究对象,收集临床、TCD及DSA相关临床资料.ABCD2评分≤3分为低危组(n=150),4～5分为中危组(n=72),6～7分为高危组(n=24).血管狭窄程度＜50％为轻度狭窄,≥50％为中重度狭窄.比较TCD和DSA分别对ABCD2评分低危组以及高危组TIA患者7d发生脑梗死的评估价值.结果 104例(42.3％)患者在TIA后7d内发生脑梗死.ABCD2评分越高,脑梗死的发生率越高(P均＜0.01).ABCD2评分中、高危患者中DSA显示血管中、重度狭窄患者(≥50％)7 d发生脑梗死的概率显著高于TCD患者(P＜0.01),而在ABCD2评分低危患者中无显著差异(P＞0.05).结论 对于ABCD2评分中、高危患者,DSA检查能准确预测7d发生脑梗死的概率.
