Venoarterial Extracorporeal Membrane Oxygenation via Direct Axillary Artery Cannulation

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an effective means of support for patients awaiting cardiac or cardiopulmonary transplantation. Typically, peripheral cannulation via the femoral vessels is preferred. However, an alternative is use of the axillary or subclavian artery, which is typically performed via a graft. Here we present the case of a patient who required VA-ECMO for cardiogenic shock with severe pulmonary hypertension as a bridge to heart-lung transplantation. Initially cannulated via the femoral artery, he was converted to a direct axillary cannulation strategy with a distal perfusion catheter and successfully bridged to transplantation. This technique avoids the use of an interposition graft and mitigates problems associated with it.
