摘要
目的:探讨ABCD2评分结合磁共振弥散加权成像(DWl)预测短暂性脑缺血发作(TIA)短期发展为脑梗死的临床价值。方法:按照ABCD2评分标准,结合DWI的检查结果,对108例TIA患者的临床资料进行分析,观察7天内脑梗死的发生率。结果:41例ABCD2评分<3分的TIA患者中无1例发生脑梗死,67例ABCD2评分≥4分的TIA患者中发生脑梗死22例(32%),且ABCD2评分越高,脑梗死发生率越高(P<0.05)。DWI异常38例,发生脑梗死8例(21%),DWI正常70例,发生脑梗死3例(4%),AB-CD2评分≥4分加DWI异常6例,发生脑梗死5例(83%),与单项异常者比较,差异有统计学意义(P<0.05)。结论:AB-CD2评分结合DWI提高了预测TIA短期发展为脑梗死的临床评估价值,对TIA的分级防治具有重要意义。
Objective:To explore the clinical value of ABCD2 score combined with diffusion-weighted imaging(DWl)for the estimation of transient ischemic attack(TIA)advancing to cerebral infarction in short-term.Method:According to the standards of the ABCD2 score,combined with DWI results,analyzed the clinical data of 108 patients with TIA,and observe the incidence of cerebral infarction with in 7 days.Results:None of TIA patients with ABCD2 scores3 advanced to cerebral Infarction.There were 67 cases with ABCD2 scores≥4,among whom 22 cases(32%),advanced to cerebral infarction.The higher ABCD2 scores.the higher incidence of cerebral infarction(P005).8 of 38 cases(21%),with DWI abnormal advanced to cerebral infarction,while 3 of 70 cases(4%),5 of 6 cases advanced to cerebral infarction with ABCD2 scores≥4plus DWI abnormal(83%).Compared with the single exception,difference was statistically significant(P005).Conclusion:ABCD2 score combined with DWI increase assessment of the value for the estimation of TIA short-term advancing to cerebral infarction,It is important to TIA's classification prevention.
