Tracheal stenting on venovenous ECMO with a dual lumen right atrium-to-pulmonary artery cannula in a COVID-19 patient with an inferior vena cava filter.

ABSTRACT

A 47-year-old man, with no medical history, was diagnosed with severe COVID-19 ARDS and pulmonary embolism. Venovenous extracorporeal membrane oxygenation (ECMO) was required for impossibility to deliver protective ventilation. The patient was weaned from ECMO after clinical improvement. An inferior vena cava filter was then positioned to prevent embolization from a persistent left femoral deep venous thrombosis. Two days after the ECMO removal, a large lesion of the tracheal posterior wall was diagnosed. Tracheal stenting was deemed necessary. ECMO support was then re-established, to safely perform the bronchoscopic procedure. Due to the presence of the inferior vena cava filter, the patient was cannulated via the right internal jugular vein with a double lumen ProtekDuo cannula. The patient was then weaned from ECMO support and invasive ventilation. The tracheal stent was removed after 40 days, showing a full recovery of the tracheal lesion. The patient was discharged home in good condition.
