Q: If a patient is cannulated for Veno-Veno (VV) extracorporeal membrane oxygenation (ECMO) via femoral and right internal jugular (R-IJ) veins, where should the tips of cannulae lie?
Answer:
Femoral (either right or left) vein is usually used to cannulate the drainage cannula. R-IJ vein can be used as an infusion cannula. Ideally, the tip of the femoral cannula should be at the junction of the inferior vena cava and right atrium, and the tip of the R-IJ cannula at the junction of the superior vena cava and right atrium.
