摘要
目的:分析ABCD2评分结合头颈CT血管造影(CTA)对短暂性脑缺血发作(TIA)后7d及30d发生脑梗死的预测价值。方法:以2011年1月～2012年12月住院治疗的198例TIA患者作为研究对象,收集其临床、头颈CTA资料。按ABCD2评分法进行评分,头颈CTA检查动脉粥样硬化致血管管腔狭窄程度,计算TIA后7 d及30 d内脑梗死发生率。结果:198例TIA患者7 d及30 d内进展为脑梗死者分别为47例(占23.7%);68例(占34.3%)。ABCD2评分越高,脑梗死的发生率越高(P<0.05)。中度狭窄组和重度狭窄或闭塞组脑梗死发生率高于正常或轻度狭窄组(P<0.05)。结论:ABCD2评分法预测TIA患者7 d及30 d发生脑梗死风险的准确性较高,进一步结合经头颈CTA检查可提高预测的准确性。
Objective： To analysis the predictive value of combined ABCD^2 scores and head CTA in cerebral infarction within 7 days and 30 days of onset of a transient ischemic attack（TIA）. Methods：The clinical data of 198 patients with TIA, admitted to our hospital from January 2011 to December 2012, were retrospectively analyzed. All patients were evaluated with ABCD^2 scale and degrees of tracheal constriction resulted from atheroscle-rosis were examined by CTA. And 7 days and 30 days follow - up of patients was performed to select those patients appearing cerebral infarction; and then, the relationships between risk of post - TIA cerebral infarction and both ABCD^2 scores and degrees of tracheal constriction were analyzed using chisquare test. Results： Among 198 TIA patients, 47（23.7% ） and 68（34.3 % ）suffered cerebral infarction within 7 days and 30 days of onset of TIA. Significant difference of risk of post- TIA cerebral infarction was noted in patients with different ABCD^2scores and degrees of tracheal constriction （P 〈0.05）： the higher the ABCD^2 scores/degrees of tracheal, the higher incidence of cerebral infarction in TIA patients. Conelusion..A rather high accuracy may be achieved with ABCD^2 scale in the prediction of short - term risk of cerebral infarction after onset of TIA, and a higher accuracy may be expected by combination of ABCD^2 scale with atherosclerosis findings.
