摘要
目的:探讨64层螺旋CT常规进行头颈CT血管造影(CTA)检查及ABCD2评分平行诊断试验对新定义短暂性脑缺血发作(TIA)后早期脑梗死进行预测的价值。方法:连续性研究了161例TIA患者,所有患者均进行了常规MRI、DWI及头颈联合CTA检查,记录TIA患者ABCD2评分、头颈动脉狭窄情况及1周内出现脑梗死的情况。结果:通过ABCD2评分预测TIA患者7天内发生脑梗死的敏感度、特异度、准确度、阳性预测值及阴性预测值分别为90.91%、89.62%、90.06%、81.96%、95.00%;通过头颈责任动脉狭窄率≥50%预测TIA患者7天内发生脑梗死的敏感度、特异度、准确度、阳性预测值及阴性预测值分别为89.09%、91.51%、90.68%、84.48%、94.17%;两种方法联合平行试验总的敏感度和特异度分别为99.01%、82.01%;序列试验总的敏感度和特异度分别为80.99%、99.12%。结论:临床ABCD2评分对TIA患者7天内发生脑梗死进行预测的敏感度高于头颈责任动脉中重度狭窄(≥50%),但头颈CTA常规检查与ABCD2评分联合应用可以明显提高预测TIA后早期脑梗死的敏感度和特异度,有助于临床医生早期采取干预措施,具有重要的临床实用价值。
