Subclavian insertion of the bicaval dual lumen cannula for venovenous extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation (ECMO) has demonstrated utility in the management of adult respiratory failure refractory to mechanical ventilation. The recent introduction of a bicaval dual-lumen ECMO cannula has improved the efficiency of venovenous ECMO and has enabled the concept of full extracorporeal respiratory support in place of mechanical ventilation. Standard placement of this cannula through the right internal jugular vein is particularly troublesome in individuals of short stature, because of excess cannula length. We describe a method for cannula placement through the left subclavian vein that is well suited for smaller patients and convenient for patient mobility.
