Introduction Brain infarction (BI) is a severe complication of extracorporeal membrane oxygenation (ECMO) with high morbidity and mortality. We aimed to determine the incidence of BI and identify predictors in pediatric patients receiving ECMO. Methods We performed a retrospective single-center cohort study including patients aged 29 days to < 18 years who underwent ECMO treatment at a tertiary center between January 2010 and October 2023. The primary outcome was BI during ECMO. Predictors of BI were analyzed using logistic regression. Results Among 179 included patients, BI was diagnosed in 51 (28%). Multivariable logistic regression identified venoarterial (VA) ECMO (OR 3.82, 95% CI 1.45-10.08; p = 0.007) and higher pre-ECMO arterial lactate (per mmol/L increase, OR 1.11, 95% CI 1.02-1.20; p = 0.01) as independent predictors of BI. The 30-day mortality was 67% among patients with BI compared with 15% among those without BI (p < 0.001). Conclusion Brain infarction was more common than in most prior reports and was associated with high short-term mortality. VA ECMO mode, compared with venovenous ECMO, and higher pre-ECMO arterial lactate were independent predictors of BI. These findings support enhanced, standardized neurological monitoring and a liberal early brain CT strategy in pediatric ECMO patients, particularly those supported with VA ECMO.
