Thrombosis is a potentially life-threatening complication in veno-arterial extracorporeal
membrane oxygenation (ECMO) circuits, which may originate from the drainage cannula
due to unfavorable blood flow dynamics. This study aims to numerically investigate the effect
of cannula design parameters on local fluid dynamics, and thus thrombosis potential, within
ECMO drainage cannulas. A control cannula based on the geometry of a 17 Fr Medtronic
drainage cannula concentrically placed in an idealized, rigid-walled geometry of the right …
