Abstract

Purpose: Proper cannula positioning in single site venovenous 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.
