There was no exacerbation of the tracheal obstruction between (a) the time of diagnosis and (b) immediately before treatment. Tracheal stenosis increased significantly from (c) the morning of the day of treatment to (d) a few hours after 2-Gy irradiation. e Tracheal intubation followed by Y-stent implantation in the trachea by rigid bronchoscopy under ECMO.

She was then transferred to a facility where tracheal stent placement was possible, and a Dumon Y-stent (Novatech, La Ciotat, France) implantation into the trachea was performed through rigid bronchoscopy under ECMO (shown in Fig. 1).
