MSCTA联合ABCD2评分对短暂性脑缺血发作早期进展为脑梗死的预测价值

The prognostic value of MSCTA combined with ABCD2 score in the early prognosis of transient ischemic attack

目的探究MSCTA联合ABCD2评分对短暂性脑缺血发作早期进展为脑梗死的预测价值。方法选取2016年6月-2017年6月本院收治的短暂性脑缺血发作(TIA)患者共92例,对所有患者行MSCTA检查以及采用ABCD2评分进行危险分层与评估,观察不同动脉狭窄程度与不同ABCD2评分下TIA患者脑梗死的发生率以及MSCTA联合ABCD2评分对TIA患者早期进展为脑梗死的预测价值。结果轻度、中度动脉狭窄患者在1周内脑梗死的发生率明显低于重度狭窄患者(P<0.05);ABCD2评分低危组与中危组患者在1周内脑梗死的发生率显著低于高危组(P<0.05);MSCTA联合ABCD2评分预测脑梗死的特异度、灵敏度、准确度、阳性预测值和阴性预测值均明显高于单独MSCTA与ABCD2评分(P<0.05)。结论 MSCTA联合ABCD2评分对短暂性脑缺血发作患者早期进展为脑梗死具有较高的预测价值。

Objective To explore the predictive value of MSCTA combined with ABCD2 score for the early prognosis of transient ischemic attack.Methods Form June 2016 to June 2017 atotal of 92 cases of patients with transient ischemic attack（TIA）were collected in our hospital,the MSCTA was used in all patients and risk stratification and assessment were made by ABCD2 score,and the incidence of cerebral infarction was observed for TIA patients under different degree of carotid stenosis and predictive value of ABCD2 score and MSCTA combined ABCD2 score on early cerebral infarction was made in patients with TIA.Results the incidence of cerebral infarction in patients with mild and moderate carotid artery stenosis was significantly lower than that in patients with severe stenosis（P〈0.05）.The incidence of cerebral infarction was significantly lower in the patients with ABCD2 score in the low-risk group and the middle critical group than that in the highrisk group（P〈0.05）.MSCTA and ABCD2 score were used to predict the specificity,sensitivity,accuracy,positive predictive value and negative predictive value of cerebral infarction,which were significantly higher than that of single MSCTA or ABCD2 score（P〈0.05）.Conclusion MSCTA combined ABCD2 score had higher predictive value early in patients with transient ischemic attack into cerebral infarction.
