磁共振快速多序列检查在超早期缺血性卒中溶栓治疗中的应用

目的 探讨磁共振（MR）在超早期缺血性卒中溶栓治疗中的应用价值。方法 对早期缺血性卒中患者32例行MR快速成像序列检查，并对筛选出的7例超早期缺血性卒中患者行静脉rt-PA静脉溶栓治疗及定期MR复查随访。结果 经MR筛选的7例超早期缺血性卒中患者行溶栓治疗后均预后良好，90 d改良Rankin评分均≤2分，Barthal指数80～100分，1例溶栓治疗3周后并发无症状性脑出血。结论 MR对筛选超早期缺血性卒中溶栓治疗患者和溶栓后复查均有较大应用价值，特别是对时间窗不明确者或发病超过6 h者受益更大。

Application of MR Fast Imaging in Thrombolytic Therapy of Ultraacute Cerebral Infarction

Objective To investigate the value of magnetic resonance(MR)in thrombolytic therapy of ultraacute cerebral infarction.Methods Total 32 patients with acute cerebral infarction were examined by MR fast imaging and among them 7 patients with ultraacute cerebral infarction were treated by recombinant human tissue-type plasminogen activator(rt-PA)intravenous injection and followed-up periodically by MR.Results The 7 patients with thrombolytic therapy had better outcome with Modified Rankin Scale of 90d less than 2 and Barthal Index of 80-100 scores.Three weeks after thrombolytic therapy 1 patient had asymptomatic intracranial hemorrhage.Conclusion MR has great value in the screen and follow-up of thrombolytic therapy for the patients,especially for those who have undefined time window or more than 6 hours.
