【摘要】：目的：回顾性分析短暂性脑缺血发作患者中DWI阳性与其临床特征的关系及其预后。方法：选择2012年1月至2013年12月到武警重庆总队医院住院治疗的短暂性脑缺血发作患者100例，根据DWI的检查结果将其分为DWI阳性组及DWI阴性组，分别比较两组患者的相关危险因素、临床表现及预后转归。结果：通过单因素分析两组患者中的相关临床特征，发现颈动脉斑块、TIA持续时间大于1小时、1周内TIA发作次数大于等于2次具有临床统计学意义（P＜0.05），且通过随访3月发现DWI阳性组有8例发生缺血性脑血管病，，DWI阴性组有5例发生缺血性脑血管病，DWI阳性组发病率明显高于DWI阴性组，P值小于0.05。结论：DWI阳性与颈动脉斑块、TIA持续时间、1周内TIA发作次数有关。DWI阳性者再发缺血性脑血管病的风险较DWI阴性者明显增高。
[Abstract]:Objective: to analyze the relationship between DWI positive and clinical features and prognosis in patients with transient ischemic attack (TIA). Methods: from January 2012 to December 2013, 100 patients with transient ischemic attack were selected and divided into DWI positive group and DWI negative group according to the results of DWI. The risk factors, clinical manifestations and prognosis were compared between the two groups. Results: the clinical characteristics of the two groups were analyzed by univariate analysis. It was found that the frequency of TIA attacks more than 2 times within 1 hour and 1 week had a significant clinical significance (P < 0.05). After 3 months follow-up, 8 cases of ischemic cerebrovascular disease were found to be negative in DWI positive group. The incidence of ischemic cerebrovascular disease in DWI positive group was significantly higher than that in DWI negative group (P < 0.05). Conclusion the incidence of recurrent ischemic cerebrovascular disease in patients with positive TIA was significantly higher than that in patients with DWI negative.
