Introduction
Methods used for cardiac and respiratory support during lung transplantation include cardiopulmonary bypass (CPB), veno-arterial extracorporeal membrane oxygenation (VA-ECMO), and veno-venous extracorporeal membrane oxygenation (VV-ECMO).1 These strategies typically require venous drainage by placing a cannula within the inferior vena cava (IVC). However, in rare instances the patient may have anomalies of the IVC, which would preclude this. Absence of the IVC has an incidence of 0.0005% to 1% in the general population.2 We present a case of a patient with absence of the IVC who required cardiopulmonary support during lung transplantation and the method employed to provide such support.
