JAMA Neurol:治疗血栓溶解后脑出血——缩短诊断时间是关键

2015-10-28 zhaozhou 译 MedSci原创

 使用重组血纤维蛋白溶酶原激活物(rtPA)治疗静脉血栓可以在四个半小时内改善缺血性卒中结果。但是,最为严重的并发症是有症状的脑出血(sICH),这一并发症发生率达6%。sICH尽管复发率很低,但其死亡率接近50%。目前治疗sICH主要是依据专家的建议,对于治疗的有效性的相关数据是很缺乏的。为了更好地了解血栓溶解相关的sICH的具体情况以及各种治疗方法的有效性。研究人员开展了一项多中心回

使用重组血纤维蛋白溶酶原激活物(rtPA)治疗静脉血栓可以在四个半小时内改善缺血性卒中结果。但是,最为严重的并发症是有症状的脑出血(sICH),这一并发症发生率达6%。sICH尽管复发率很低,但其死亡率接近50%。目前治疗sICH主要是依据专家的建议,对于治疗的有效性的相关数据是很缺乏的。为了更好地了解血栓溶解相关的sICH的具体情况以及各种治疗方法的有效性。研究人员开展了一项多中心回顾性试验。
 

在2009年1月到2014年4月底期间,研究人员在美国10个大型卒中研究中心开展了此次研究。受试者全部是患有sICH的患者。主要监测结果是住院死亡率。次要结果则是血肿扩张,即血肿在成像监测中出现33%以上的增加。共有3894名患者在缺血性卒中发生的四个半小时之内接受了静脉注射重组组织血纤维蛋白溶酶原治疗,其中128人(3.3%)患有sICH。从rtPA治疗到诊断出sICH的中位时间为470分钟,从诊断出sICH到治疗sICH的中位时间为112分钟。住院死亡率为52.3%(128人中有67人死亡),26.8%出现了血肿扩张。研究还发现,严重的低蛋白纤维血症是和血肿扩张有关的。
 
通过此次回顾性研究,对血栓溶解后的sICH的治疗并不能显著地降低住院死亡率或者血肿扩张的可能性。缩短诊断和治疗的时间或许是改善有症脑出血病人结果的关键所在。

ACS 2015:新型多肽探针有助于检测全身血栓部位
