Double Y-stent placement for tracheobronchial stenosis.

The silicone stent has been widely used to re-establish airway patency for patients with airway stenosis. The ideal shape of the stent should be well adapted to the tracheobronchial anatomic structures, and its optimal length should cover the entire inner wall of the stenotic airway. Although the silicone Y-stent was developed as a dedicated prosthesis for main carinal stenosis, we often encounter patients with tracheobronchial stenosis that cannot be treated by a single silicone Y-stent. The present study reports 2 cases of malignant disease who underwent double Y-stent placement on the involved carina between the right upper lobe bronchus and the bronchus intermedius as well as on the involved main carina as a unit. The procedure provided successful palliation.
