CTICasesVV-ECMO Cannula Malposition
Imaging findings
A patient on VV-ECMO had two cannulae in the IVC separated by only ~2 cm.
Key takeaways
If inflow and outflow cannulae are too close, it causes a recirculation phenomenon where oxygenated blood is immediately sucked back out, rendering the ECMO ineffective. Adequate separation (approx. 10 cm) is required.
