Intermedius bronchus

The series from Brescia, Italy reported by Cavaliere et al. comprises 306 patients and placement of 393 silicone stents (Cavaliere et al. 1996). The vast majority of patients were treated with 363 Dumon stents in 27 cases a Y-shaped Hood stent was placed, and in another four cases a Y-shaped Dynamic stent. Stents were inserted into the trachea in 38.7%, right main stem bronchus and bronchus intermedius in 19.8%, left main stem bronchus in 15.5%, trachea and right or left main stem bronchus in 13.5%, and in other positions in 12.5%. Stent insertion resulted in improvement in pulmonary function tests and quality of life in all but six patients (98% success rate). The median survival of patients was 108 days. All patients had malignant tracheobronchial tumors.
