Abstract
Extracorporeal circulatory support revolutionized the field of cardiothoracic surgery, initially in the form of cardiopulmonary bypass (CPB) and then in its modified form, extracorporeal membrane oxygenation (ECMO). Although initial cannulation techniques involved open intrathoracic approaches, the increased prevalence of reoperative sternotomies and the emergence of minimally invasive surgery encouraged the development of peripheral cannulation methods and configurations. The Avalon Elite Bicaval Dual Lumen catheter (Avalon Laboratories, LLC, CA) can be placed in the right internal jugular vein to provide venovenous (VV) ECMO. However, some patients on VV ECMO then develop compromised cardiac performance. We describe two ways in which the Avalon Elite was used, first for complete venous drainage through a single peripheral site for CPB and in the other to convert a patient on VV ECMO to axillary artery venoarterial (VA) ECMO.
