Abstract

Purpose

Proper cannula positioning in single site veno-venous extracorporeal life support (vv-ELS) is cumbersome and necessitates image guidance to obtain a safe and stable position within the heart and the caval veins. Importantly, image-guided cannula positioning alone is not sufficient, as possible recirculation cannot be quantified.

Methods and results

We present an ultrasound dilution technique allowing quantification of recirculation for optimizing vv-ELS.

Conclusion

We suggest quantification of recirculation in addition to image guidance to provide optimal vv-ELS.
