ABCD评分结合磁共振弥散加权成像预测短暂性脑缺血发作短期发展为脑梗死的临床价值

The clinical value of ABCD score combined with diffuse weighing imaging for the estimation of transient ischemic attack advancing to cerebral infarction

目的探讨ABCD评分结合磁共振弥散加权成像（DwI）对短暂性脑缺血发作（1rIA）后7d内发生脑梗死的临床评估价值。方法按照ABCD评分标准，同时收集DWI的检查结果，对105例TIA患者的临床资料进行分析。结果22例ABCD评分〈3分的TIA患者中无一例发生脑梗死，83例ABCD评分≥3分的TIA患者中发生脑梗死24例（28．9％），且ABCD评分越高，脑梗死发生率越高（P〈0．01）。DWI异常者42例，发生脑梗死9例（21．4％），DWI正常者50例，发生脑梗死2例（4．O％），两者比较差异有统计学意义（P〈0．05）。结论ABCD评分是临床预测TIA短期发展为脑梗死的有效方法．结合DWI更能提高其临床评估价值。

Objective To investigate the clinical value of ABCD score combined with diffuse weighing imaging（ DWI ）for the estimation of transient ischemic attack （TIA） advancing to cerebral infarction in 7 days. Method The clinical data including ABCD score and DWI of 105 cases with TIA were analyzed. Results None of TIA patients with ABCD scores 〈 3 advanced to cerebral infarction. There were 83 cases with ABCD scores ≥3, among whom 24 cases （28.9%）advanced to cerebral infarction. The higher ABCD scores, the higher incidence of cerebral infarction （P 〈 0.01 ）. Nine of 42 cases （21.4% ） with DWI abnormal advanced to cerebral infarction, while 2 of 50 cases （4.0%）with normal DWI advanced to cerebral infarction （P 〈 0.05 ）. Conclusion ABCD score is an effective method for the estimation of TIA advancing to cerebral infarction, and when combined with DWI it is more efficient.
