摘要
目的分析ABCD2评分结合经颅多普勒和颈部血管超声对短暂性脑缺血发作(TIA)后7 d发生脑梗死的评估价值。方法以2010年1月～2011年1月住院治疗的126例TIA患者作为研究对象,收集其临床、TCD和颈部血管超声检查资料。按ABCD2评分法进行评分,计算TIA后7 d内脑梗死发生率。结果 126例TIA患者7 d内进展为脑梗死者26例,占20.6%。ABCD2评分越高,脑梗死的发生率越高(P<0.05)。TIA后7 d脑供血动脉狭窄≥50%的患者中脑梗死发生率较脑供血动脉狭窄<50%的患者明显升高(P<0.05)。ABCD2评分≥4分、脑供血动脉狭窄≥50%的TIA患者7 d脑梗死发生率为33.8%,与ABCD2评分≥4分、脑供血动脉狭窄<50%的TIA患者(7.7%)比较,其发生脑梗死的风险明显增加(P<0.05)。结论 ABCD2评分法预测7 d发生脑梗死风险的准确性较高,进一步结合经颅多普勒和颈部血管超声检查可提高预测的准确性。
Objective To analyze the evaluation value of ABCD2 score combined with transcranial doppler and ultrasound of cervical vessels on the incidence of cerebral infarction after TIA. Methods 126 TIA inpatients were taken as research object.Their clinical data and examination results of ranscranial doppler and cervical vessels ultrasound.ABCD2 Score was conducted.The rate of cerebral infarction caused by TIA in seven days was calculated. Results In the 126 TIA inpatients,26（20.6%） progressed to cerebral infarction.The higher the ABCD2 score is,the higher the rate of cerebral infarction is（P0.05）.The rate of cerebral infarction of the TIA patients after seven days with cerebrovascular stenosis≥50% is higher than that of the patients with cerebrovascular stenosis50%（P0.05）.The rate of cerebral infarction in the TIA patients with ABCD2 Score≥4 and cerebrovascular stenosis≥50% is 33.8% in seven days,and the risk of developing cerebral infarction increased more significantly than the TIA patients with ABCD2 Score≥4 and cerebrovascular stenosis50%（7.7%）（P0.05）. Conclusions The accuracy of forecasting the risk of developing cerebral infarction seven days after TIA by ABCD2 score is good,and the accuracy can be improved by combining with transcranial doppler and cervical vessels ultrasound.
