Double lumen cannula and inferior vena cava filter.. Inferior vena cava filter and tip of the double lumen cannula was
confirmed with daily x-rays due to potential filter migration. The white
arrow indicates the tip of the double lumen cannula, and the black arrow
indicates the inferior vena cava filter.

Because there were some concerns about inferior vena cava filter migration due to the suction generated by the ECMO pump, daily abdominal and chest x-rays were performed, and the distance between the inferior vena cava filter and the tip of the DL cannula remained unchanged during the entire ECMO run (Figure 1).
Extracorporeal membrane oxygenation circuit monitoring the entire
run.. There were no problems during the run with resistance to blood flow or
with the pump load conditions, which was evaluated as blood flow to the
rotation ratio. ML resistance - membrane lung resistance to blood flow;
BF/RR - blood flow to rotation ratio.

The ECMO flow, resistance of the oxygenator and blood flow to the rotation of the pump ratio, and system pressures remained within acceptable ranges (Figure 2).
Inferior vena cava filter with trapped thrombi.. The inferior vena cava filter was left in place after the extracorporeal
membrane oxygenation run due to the trapped thrombi in the filter
despite adequate anticoagulation treatment during extracorporeal
membrane oxygenation.

The inferior vena cava filter was left in place due to evidence of thrombi trapped in it (Figure 3).
