Novel Leg Cannula for Venous Decompression in Peripheral Extracorporeal Membrane Oxygenation.

A chimney femoral artery graft for peripheral extracorporeal membrane oxygenation can potentially cause hyperperfusion and subsequent venous congestion in the ipsilateral leg, especially in the context of septic shock and higher flow requirement. This report describes a novel technique to use an additional leg venous cannula to avoid leg congestion as well as to achieve higher total flow.
