Stroke:新技术——高级神经血管通路血栓切除系统治疗急性卒中安全有效!

2022-04-05 网络 网络

在这一临床经验中,ANA设备实现了较高的完全再通率,具有初步良好的安全性和有利的90天临床结果。

高级神经血管通路(ANA)血栓切除系统是一种新型的中风血栓切除装置,包括一个自我膨胀的漏斗,旨在通过局部限制血流来减少血栓的破碎,同时变得与所处的动脉一样宽。一旦展开,ANA设备允许远端抽吸,结合支架回收器,将血栓动员到漏斗中,在抽吸过程中,血栓仍被夹住。

近期,来自西班牙巴塞罗那的学者开展了一项名为SOLONDA  前瞻性、开放式、单臂、多中心试验,旨在调查了ANA导管系统的安全性和有效性,结果发表在近期stroke杂志上。

该研究纳入所有卒中症状发生后8小时内入院的前循环血管闭塞患者符合条件。主要终点是在有意治疗的人群中,在使用抢救治疗之前,使用ANA设备结合支架取出器,成功进行再灌注(改良的脑梗塞溶栓评分2b-3)。主要的预定义分析是与HERMES(使用多种血管内设备的高效再灌注)中观察到的性能终点相比的非劣效性。

在招募了74名患者后,进行了中期分析,由于达到了安全和绩效目标,试验指导委员会决定终止招募。平均年龄为71.6(SD 8.9)岁,46.6%为女性,入院时美国国立卫生研究院卒中量表NIHSS评分中位数为14(IQR:10-19)。

60/72名患者在抢救治疗前的3个通道内成功实现了再灌注(83.3%[95%CI,74.7%-91.9%]),完全再灌注率(改良的脑梗塞溶栓评分2c-3)为60%(43/72; 95%CI,48.4%-71.1%)。在非劣效性得到确认后(P<0.01),ANA设备在≤3次的成功再灌注率方面也显示出优越性(P=0.02)。

90天后画着mRS评分结局

总的来说,第一次成功再通率为55.6%(95%CI,44.1%-67.0%),第一次完全再通率为38.9%(95%CI,27.6%-50.1%)。12/72(17%)名患者需要进行抢救性治疗以获得修改后的脑梗塞溶栓评分2b-3。90天后,良好的功能结果(mRS 0-2)的比率为57.5%(95%CI,46.2%-68.9%),优秀的功能结果(mRS 0-1)比率为45.2%(95%CI,33.8%-56.6%)。

在这一临床经验中,ANA设备实现了较高的完全再通率,具有初步良好的安全性和有利的90天临床结果。

晚期窗口期(6-24小时)出现大血管闭塞(LVO)中风患者的比例很大。如果不能实现再灌注,这些患者预后不良,估计死亡率或严重发病率约为40%。两项随机试验表明,血管内血栓切除术(EVT)可显著改善晚期

Stroke:卒中患者血栓切除术后血压与预后的关系

缺血性卒中患者机械性血栓切除术后的结局可能受血压(BP)影响。近日,Stroke杂志发表一项最新研究,评估对比了行机械性血栓切除术后的患者全身麻醉期与清醒镇静下血压变化与预后的关系。

NEJM:如何遵循DAWN试验在临床中开展血管内治疗?

以前的随机试验显示对于发病6h内急性缺血性卒中采取血管内血栓切除术能够获益,这种获益随着从看起来正常到血栓切除术之间的时间间隔延长而减弱。为了筛选溶栓或血栓切除术的患者,患者看起来正常的时间通常被认为是卒中发作的时间,包括醒后卒中或不确定时间的卒中。从最后看起来正常计算,症状超过6h采取血栓切除术的疗效尚不清楚,特别是尚未梗死的缺血脑组织和再灌注后可挽救的脑组织。

NEJM:大血管闭塞性急性缺血性卒中患者血栓切除前是否需要溶栓治疗
