Given the perceived high risk of tracheal resection and anastomosis, bronchoscopic cryotherapy with a 1.1 mm, flexible cryoprobe was performed for cryobiopsy and cryo-debulking. The masses occluded 80-90% of the lumen and were completely removed with cryotherapy, with immediate clinical improvement and decreased airway resistance (279 to 31 cmH₂O/l/s).
