摘要
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。
Aim： To explore the prognostic value of combined ABCD2 score and CTA in evaluating brain infarction 7 days after the onset of a transient ischemic attack（TIA）.Methods： The clinical data and CTA findings of 120 hospitalized TIA patients from Dec.2008 to Mar.2011 were analyzed.The relationship of all the parameters,including different ABCD2 scores and varied CTA manifestations,to the risk of post TIA cerebral infarction were analyzed by using Chi-square test.Results： Of 120 patients,31 of them（25.83%） suffered cerebral infarction within 7 days after onset of TIA.Patients in high risk group（scoring 6-7） were most likely to experience cerebral infarction,then in moderate（scoring 4-5） and low risk group（scoring 0-3）.The incidence of cerebral infarction at day 7 was higher in the patients with≥50% intra-and extra-cranial arterial stenosis than those with50% intra-and extra-cranial arterial stenosis（P0.01）.Conclusion： A rather high accuracy may be achieved with ABCD2 score in prediction of short-term risk of cerebral infarction after onset of TIA,and an enhanced accuracy may be expected by combination of ABCD2 score with CTA findings.
