Concurrent veno-pulmonary extracorporeal membrane oxygenation cannulation with ProtekDuo parallel to an in situ veno-pulmonary single-lumen cannula.

This technical report describes the successful transition from dual lumen, single site veno-venous extracorporeal membrane oxygenation ((dl)V-V ECMO) to single lumen, dual site veno-pulmonary (V-P) ECMO, and subsequently to dual lumen, single site (dl)V-P ECMO involving temporary placement of two cannulas in the main pulmonary artery. No complications were observed during these transitions. This technique could address concerns related to cannula exchanges in VP ECMO. However, caution is warranted and constant monitoring of cannula position using real-time imaging is required when using this technique due to the risk profile.
