Use of the Dumon Y-stent with High Frequency Jet Ventilation Under Veno-venous Extracorporeal Membrane Oxygenation (V-V ECMO) in the Management of Severe Advanced Airway Constriction

Abstract

Background. Ventilation failure during airway intervention for airway constriction can be a fatal complication. Management of this complication is important. Case. A 68-year-old woman developed acute severe respiratory failure and could not breathe in the supine position. Stenosis from above the carina to both sides of the main bronchi was present due to thymic cancer oppression and infiltration. Under veno-venous extracorporeal membrane oxygenation (V-V ECMO), Dumon Y-stent placement was carried out using high frequency jet ventilation. Conclusion. V-V ECMO and the high frequency jet ventilation method can be a useful auxiliary means for airway intervention even in the presence of severe airway stenosis.
