Background The mechanisms and outcomes in COVID-19- associated stroke are unique from those of non-COVID-19 stroke. Objectives The purpose of this study is to describe the efficacy and outcomes of acute revascularization of large vessel occlusion (LVO) in the setting of COVID-19 in an international cohort. Methods We conducted an international multicenter retrospective study of consecutively admitted COVID-19 patients with concomitant acute large vessel occlusion (LVO) across 50 comprehensive stroke centers. Our control group constituted historical controls of patients presenting with LVO and receiving a MT between January 2018 to December 2020.Results: The total cohort was 575 patients with acute LVO, 194 had COVID-19 while 381 patients did not. Patients in the COVID-19 group were younger (62.5 vs. 71.2;p<0.001), and lacked vascular risk factors (49, 25.3% vs. 54, 14.2%;p =0.001). mTICI 3 revascularization was less common in the COVID-19 group (74, 39.2% vs. 252, 67.2%;p < 0.001). Poor functional outcome at discharge (defined as mRS 3-6) was more common in the COVID-19 group (150, 79.8% vs.132, 66.7%;p =0.004). COVID-19 was independently associated with a lower likelihood of achieving mTICI 3 (OR: 0.4, 95% CI: 0.2 -0.7;p<0.001), and unfavorable outcomes (OR: 2.5, 95% CI: 1.4 - 4.5;p=0.002). Conclusion COVID-19 was an independent predictor of incomplete revascularization and poor outcomes in patients with stroke due to LVO. COVID-19 patients with LVO patients were younger, had fewer cerebrovascular risk factors, and suffered from higher morbidity/mortality rates. (Figure Presented).
背景COVID-19相关卒中的机制和结局与非COVID-19卒中不同。本研究的目的是在一个国际队列中描述COVID-19背景下大血管闭塞急性血运重建术(LVO)的疗效和结果。方法对50个卒中综合中心连续入院的COVID-19合并急性大血管闭塞(LVO)患者进行国际多中心回顾性研究。我们的对照组是2018年1月至2020年12月期间出现LVO并接受MT的患者的历史对照组。结果:共575例急性LVO患者，其中194例合并COVID-19, 381例未合并。COVID-19组患者更年轻(62.5 vs. 71.2;p<0.001)，缺乏血管危险因素(49,25.3% vs. 54, 14.2%;p =0.001)。mTICI 3型血运重建术在COVID-19组较少见(74,39.2% vs. 252,67.2%;p < 0.001)。出院时功能预后差(定义为mRS 3-6)在COVID-19组中更为常见(150,79.8% vs.132, 66.7%;p =0.004)。COVID-19与实现mTICI 3的可能性较低(OR: 0.4, 95% CI: 0.2 -0.7;p<0.001)和不良结局(OR: 2.5, 95% CI: 1.4 - 4.5;p=0.002)独立相关。结论COVID-19是LVO脑卒中患者血运不完全重建和预后不良的独立预测因子。COVID-19患者合并LVO患者年龄较小，脑血管危险因素较少，发病率/死亡率较高。(图)。
