Treatment of severe carinal stenosis with overlapping metallic endoprosthesis.

A 50-year-old man presented with respiratory distress from central airway compression secondary to malignant mediastinal adenopathy. The stenosis involved the carinal triangle and created residual luminal diameters of 6 mm, 6 mm, and pinhole in the distal trachea and right and left mainstem bronchi, respectively. Airway patency at the carina was restored successfully with a stenting method that uses two overlapping Wall stents.
