Cerebrovascular Complications of COVID-19 on Venovenous Extracorporeal Membrane Oxygenation
OBJECTIVES: Evidence of cerebrovascular complications in COVID-19 requiring venovenous extracorporeal membrane oxygenation (ECMO) is limited. Our study aims to characterize the prevalence and risk factors of stroke secondary to COVID-19 in patients on venovenous ECMO. DESIGN: We analyzed prospectively collected observational data, using univariable and multivariable survival modeling to identify risk factors for stroke. Cox proportional hazards and Fine-Gray models were used, with death and discharge treated as competing risks. SETTING: Three hundred eighty institutions in 53 countries in the COVID-19 Critical Care Consortium (COVID Critical) registry. PATIENTS: Adult COVID-19 patients who were supported by venovenous ECMO. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Five hundred ninety-five patients (median age [interquartile range], 51 yr [42–59 yr] ; male: 70.8%) had venovenous ECMO support. Forty-three patients (7.2%) suffered strokes, 83.7% of which ere hemorrhagic. In multivariable survival analysis, obesity (adjusted hazard ratio [aHR], 2.19 ; 95% CI, 1.05–4.59) and use of vasopressors before ECMO (aHR, 2.37 ; 95% CI, 1.08–5.22) were associated with an increased risk of stroke. Forty-eight-hour post-ECMO Paco2–pre-ECMO Paco2/pre-ECMO Paco2 (relative ΔPaco2) of negative 26% and 48-hour post-ECMO Pao2–pre-ECMO Pao2/pre-ECMO Pao2 (relative ΔPao2) of positive 24% at 48 hours of ECMO initiation were observed in stroke patients in comparison to relative ΔPaco2 of negative 17% and relative ΔPao2 of positive 7% in the nonstroke group. Patients with acute stroke had a 79% in- hospital mortality compared with 45% mortality for stroke-free patients. CONCLUSIONS: Our study highlights the association of obesity and pre-ECMO vasopressor use with the development of stroke in COVID-19 patients on venovenous ECMO. Also, the importance of relative decrease in Paco2 and moderate hyperoxia within 48 hours after ECMO initiation were additional risk factors.
