Hemodynamics in femoro-femoral venovenous extracorporeal membrane oxygenation using large eddy simulations.

ABSTRACT: Venovenous extracorporeal membrane oxygenation (ECMO) is used for support in refractory severe respiratory failure. Venous drainage and return are accomplished through cannulation of patient's major veins, typically on the neck and/or the groins. Cannulation configuration may affect treatment efficiency, but it remains unclear if any strategy is superior. Computational fluid dynamics was used to evaluate and compare the femoro-femoral (FF), jugulo-femoral (JF), and femoro-jugular (FJ) cannulation configurations. Cannulae were modelled in an adult patient-averaged geometry of the right atrium and venae cavae. Large eddy simulations were performed at ECMO flow rates of 2-6 L/min. Time-averaged flow data was collected for assessment of flow parameters associated with clinical efficiency. FF c
