A 66-year-old @entity1 was admitted to Saiseikai Suita Hospital with stridor and @entity1353 . The flow-volume curve showed central @entity1224 pattern. Although a P-A chest roentogenogram was normal, chest tomogram demonstrated a @entity5 shadow in the lower portion of the @entity825 . Chest CT examination demonstrated a @entity5 arising from the posterior wall of the lower portion of the @entity825 and @entity850 with wall thickening extending from the lower portion of the @entity825 to both main bronchi. Bronchofiberscopic examination revealed @entity5 obstructing the lower portion of the tracheal lumen, and biopsy was subsequently performed. On the night immediately after the bronchofiberscopic examination, the patent suddenly choked, and emergency intubation was performed. @entity2347 was diagnosed on biopsy and we decided to place a spiral Z-stent. A reversed gamma-type stent placement was used. The first spiral Z-stent extended from the @entity825 to the right main bronchus and the second spiral Z-stent was placed in the left main bronchus through the first stent. Following the spiral Z-stent placement radiotherapy was performed. Spiral Z-stent placement resulted in dilation of the stenotic @entity825 and both main bronchi.

[A case of XXXX presenting with stridor and which was treated by reversed gamma type stent placement].
