Transition of femoral-jugular to dual-stage left subclavian without discontinuation of extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation (ECMO) is a technology that has allowed further cardiopulmonary support in the setting of respiratory failure refractory to mechanical ventilation. While it has evolved since its first description, one area of improvement continues to be its implementation. With advancements in cannulation techniques, in recent years, there has been a plethora of new cannulas that has been introduced in the market. For urgent venous-venous cannulation, the right internal jugular vein along with either femoral veins remain the most utilized strategy due to minimal need for imaging support. This allows for safe bedside cannulation. However, as the number of days of ECMO support continue to increase, transitioning to a cannulation strategy that is easier to ambulate with and more comfortable is preferred. Therefore, we describe a method for transitioning from right jugular-femoral cannulation to left subclavian placement of the Crescent Dual-Lumen catheter without interrupting ECMO support.
