17项关于静脉或动脉溶栓包括了5216个病人[1]。其中15项是双盲研
究。这些研究检验了尿激酶、链激酶、rt-PA或重组前尿激酶。有2项研究是动脉介
入治疗,其余都是静脉治疗。溶栓治疗的主要危险是症状性脑出血。6h内进行溶栓
治疗可以明显减少病人的死亡率和生活依赖性。在中风发生3h内进行溶栓治疗的病
人,可以取得更好的疗效。rt-PA静脉溶栓治疗研究显示比其他药物危险性更小和
疗效更好。有一项研究是溶栓药物加阿司匹林,其结果显示比单独用溶栓药物的死
亡率要高。
6结论
现在,对急性缺血性中风的病人,已经能够提供安全有效的治疗。对症状发生
在3h内的病人,t-PA静脉溶栓治疗是安全的,并能改善症状。动脉重建技术可以使
大脑中动脉的血流更完全地恢复,达到比静脉溶栓更好的疗效。如果在症状发生的
6h内进行动脉溶栓治疗,可以取得更好的临床效果。
