The Avalon dual lumen cannula is presently the cannula of choice for veno-venous extracorporeal membrane oxygenation (VV-ECMO) via right internal jugular cannulation. This cannula establishes VV-ECMO with a single cannulation; however, it requires appropriate positioning to gain adequate oxygenation. Malposition of this cannula can cause inadequate ECMO flow, hypoxia, and structural injury. We have experienced two cases of migration: one into the hepatic vein and the other into the right ventricle. The former was repositioned using echocardiographic guidance without using a guidewire. The latter was repositioned using a guidewire from the femoral vein under fluoroscopy, without antegrade wire placement into the Avalon cannula, discontinuation of ECMO, or bleeding.
