摘要 目的:观察在 MR 灌注影像指导下,重组组织型纤溶酶原激活剂 (r-tPA) 静脉内溶栓治疗不同时间窗急性脑梗死的疗效及并发症.方法:分别对 21 例发病后 4.5 h 内和 33 例 4.5~9 h 内头颅 MR 灌注和弥散不匹配区域≥ 20% 的急性缺血性脑梗死患者行静脉内 r-tPA溶栓治疗,观察治疗前后 NIHSS 评定神经功能恢复状况,治疗后和随访期用 Barthel 指数评价临床疗效.结果:不同时间窗内的 r-tPA 溶栓静脉治疗后 NIHSS 的评分均有明显改善,临床疗效明显.结论:在 MR 的 PWI/DWI 不匹配区域≥ 20% 的情况下,大脑中动脉供血区脑梗死 4.5 h 内和 4.5~9 h 两个时间窗,用 r-tPA 静脉溶栓均安全有效.
