Application value of multi-slice spiral CT angiography combined with ABCD2 score in predicting the early progression of transient ischemic attack to cerebral infarction

目的探讨多层螺旋CT血管成像联合ABCD2评分在短暂性脑缺血发作早期进展为脑梗死预测中的应用价值.方法对89例短暂性脑缺血发作患者(其中3个月内进展为脑梗死16例,未进展为脑梗死73例)入院时均行多层螺旋CT血管成像联合ABCD2评分预测,统计分析多层螺旋CT血管成像、ABCD2评分及二者联合预测脑梗死结果.结果本组经多层螺旋CT血管成像预测脑梗死9例,经ABCD2评分预测脑梗死7例,经二者联合预测脑梗死15例;多层螺旋CT血管成像与ABCD2评分二者联合预测脑梗死准确度(96.63%)、特异度(97.26%)、灵敏度(93.75%)显著高于单一预测(P<0.01).结论采取多层螺旋CT血管成像联合ABCD2评分可提高短暂性脑缺血发作早期进展为脑梗死预测的准确度、特异度、灵敏度,有利于指导临床采取预见性措施,降低脑梗死发生率.

Objective To explore the application value of multi-slice spiral CT angiography combined with ABCD2 score in predicting the early progression of transient ischemic attack to cerebral infarction.Methods 89 patients with transient ischemic attack were selected.Among them,16 patients developed into cerebral infarction within 3 months and 73 patients did not develop into cerebral infarction.At admission,multi-slice spiral CT angiography combined with ABCD2 score was used to predict the outcome of cerebral infarction.Analyze the multislice spiral CT angiography and ABCD2 score,and the combined prediction of cerebral infarction results.Results 9 cases of cerebral infarction were predicted by multi-slice spiral CT angiography,7 cases were predicted by ABCD2 score and 15 cases were predicted by combination.The accuracy,specificity and sensitivity of multi-slice spiral CT angiography and ABCD2 score in predicting cerebral infarction were 96.63%,97.26%and 93.75%,higher than that of single prediction(P<0.01).Conclusions The combination of multi-slice spiral CT angiography and ABCD2 score can improve the accuracy,specificity and sensitivity of the prediction in the early stage of transient ischemic attack,which is helpful to guide the clinic to take predictive measures and reduce the incidence of cerebral infarction.
