 一项最新研究表明,在早期入院且年龄大于70岁或患有轻度中风的患者中,一种可增加脑血流量的新型导管治疗(NeuroFlo)法对其全因死亡率有效,但是否适合临床普及,尚有待进一步的确认。该项研究成果已在线发表于《卒中》期刊网站。


目前,接受治疗的急性局部缺血性脑卒中患者不足5%,而且其对额外可选择的疗法尚有需求。一种可增加脑血流量的新型导管治疗(NeuroFlo)接受了长达14小时的检测;在这项研究NeuroFlo治疗急性局部缺血性脑卒中的随机试验中,对比NeuroFlo疗法与标准疗法在改善神经性预后方面的安全性和疗效。主要安全终点为治疗90天中严重不良事件的发生。改良意向治疗人群的主要疗效终点为治疗90天时总的残疾终点。次级终点包括死亡率、颅内出血、改良Rankin量表评分结构为0-2分以及改良Rankin量表转换分析。

结果发现,2005年10月至2010年1月期间,9个国家的68个治疗中心共招募了515名患者。主要疗效终点无统计学意义(OR为1.17; CI为0.81–1.67; P=0.407)。主要安全终点在严重不良事件中未表现出统计学差异(P=0.923)。治疗组和对照组90天的死亡率分别为11.3% (26/230)和16.3% (42/257) (P=0.087)。因果关系分析显示,中风后5小时(OR为 3.33;CI为 1.31–8.48)内入院且NIHSS评分为8-14分(OR为1.80;CI为0.99–3.30)或年龄大于70岁(OR为2.02;CI为1.02–4.03)的患者其改良Rankin量表评分结果较好,为0-2分;而且,与对照组相比,治疗组与中风相关的死亡人数较少(7.4%=17/230;14.4%=37/257)。

该实验达到了主要安全终点但未达到主要疗效终点。在早期入院且年龄大于70岁或患有轻度中风的患者中,结果提示该疗法对其全因死亡率有效,但有待进一步的确认。
