Multisite Venovenous Extracorporeal Membrane Oxygenation in Pediatric Patients Under 15 kg: Three-Center, Analysis of Surgical Versus Percutaneous Approach and Thrombosis Risk, 2017–2024

This retrospective case series of VVMS in neonates and small children (< 15 kg) shows that surgical cannulation was associated with greater odds of vascular thrombosis at vessel sites, but a potential confounder may be that the surgical group were younger and of smaller weight. Overall, for any given weight, percutaneous cannulas were smaller than those placed surgically.
