Stroke:当代颅内颈内动脉闭塞的搭桥手术

针对颅内颈内动脉(ICA)闭塞,有人提出建议通过颅外-颅内( extracranial to intracranial,EC-IC)、颞浅动脉-大脑中动脉(superficial temporal artery to middle cerebral artery ,STA-MCA)搭桥的策略以增加脑血流量,但目前的实践受到2011年发表的COSS随机对照试验阴性结果的严重影响。

COSS试验的目的是探讨STA-MCA搭桥手术对动脉粥样硬化性单侧颈内动脉闭塞(atherosclerotic unilateral internal artery occlusion,A-ICAO)患者的疗效。主要纳入标准为(1)血管成像显示ICA完全闭塞,(2)120天内在闭塞 ICA 供血区半球临床诊断 TIA 或缺血性卒中,(3)PET 显示同侧/对侧摄氧分数比值>1.130。然而,由于围手术期卒中发生率高,内科管理患者的缺血性事件发生率低于预期,抵消了随访期间手术的有效性,COSS试验被迫提前终止。然而,神经学家和血管界仍然推荐A-ICAO患者进行搭桥手术,这就提出了一个问题:是否这些被推荐的患者病情更加严重。

图1.2008-2019年间STA-MCA搭桥手术的每年数量:

COSS的结果会对临床决策产生普遍的影响,因此我们分析了当今的动脉硬化血管闭塞搭桥手术患者的特征,以评估这些患者是否与COSS中报告的人群是否具有不同的特征。2021年10月来自德国的Peter Vajkoczy等在 Stroke 上公布了他们的研究结果。

他们回顾性分析了COSS发表后所有因动脉粥样硬化性脑血管病转诊到他们中心进行STA-MCA搭桥手术的患者。

图2.单侧和双侧血流动力学受损的示例:

2012年至2019年间,179名患者转诊到研究者中心接受186次搭桥手术。91例(51%)患有动脉粥样硬化单侧颈内动脉闭塞,88例(49%)患有动脉粥样硬化性多血管疾病。所有患者均接受了强化内科管理。

根据COSS的纳入标准,在过去120天内,179名患者中只有36名(20%)发生过一次TIA或缺血性卒中,而27名(15%)发生过一次以上的TIA,109名(61%)发生过复发性轻型缺血性卒中,7名(4%)血流动力学不稳定需要维持血压。动脉粥样硬化性单侧颈内动脉闭塞和动脉粥样硬化性多血管疾病两组患者的症状分布没有差异(P=0.376),但在动脉粥样硬化性多血管疾病中血流动力学受损更明显(P<0.001)。围手术期总卒中率为4.3%。

最终作者认为,与COSS试验的患者相比,当今接受血流增强手术患者的症状和血管阻塞模式更加严重。考虑到严重动脉粥样硬化性脑血管病的预后仍然很差,进行一项新的、精心设计的随机对照试验似乎是值得的。
