目的:分析ABCD2评分结合头颈CT血管成像(CTA)表现对短暂性脑缺血发作(TIA)后7 d患者发生脑梗死的评估价值。方法:以2008年12月至2011年3月住院的120例TIA患者为研究对象,收集相关资料并进行率的χ2检验。结果:31/120例(25.83%)患者在TIA后7 d内发生脑梗死。ABCD2评分≥6分为高危组,ABCD2评分4~5分为中危组,ABCD2评分≤3分为低危组。TIA后7 d脑梗死发生率,CTA颅内外动脉狭窄≥50%的患者中与<50%的患者相比明显增高(P<0.01)。结论:ABCD2评分法预测7 d发生脑梗死风险的准确性较高,进一步结合CTA检查能提高预测的准确性。
OBJECTIVE: To evaluate the diagnostic value of ABCD2 combined with CT angiography (CTA) in patients with cerebral infarction at 7 days after transient ischemic attack (TIA). Methods: A total of 120 TIA patients hospitalized from December 2008 to March 2011 were recruited. The relevant data were collected and the rate of χ2 test was performed. Results: 31/120 (25.83%) patients developed cerebral infarction within 7 days after TIA. ABCD2 score≥6 was divided into high risk group, ABCD2 score 4 ~ 5 was divided into medium risk group, ABCD2 score≤3 was divided into low risk group. The incidence of cerebral infarction at 7 days after TIA was significantly higher than that in patients with <50% (P <0.01) in patients with CTA ≥50%. Conclusion: The accuracy of ABCD2 score in predicting the risk of cerebral infarction at 7 days is higher, and further combining with CTA can improve the prediction accuracy.
