    Abstract:
    Prosthetic tracheobronchial stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. Over a 1-year period, 28 Gianturco expanding wire stents were used in 15 patients for nonneoplastic indications: pure fibrous airway stenosis (6), fibroinflammatory stenosis (4), and tracheobronchial malacia (5). Insertion was technically straightforward. A satisfactory airway lumen with immediate improvement in ventilatory function was obtained in all patients. After insertion all patients had an irritation-type cough that either subsided spontaneously (10 patients) or was successfully suppressed with inhaled corticosteroid therapy (5 patients). The most common complication (12 patients) was granuloma formation leading to stent removal in 3 patients with fibroinflammatory stenosis. Other complications were dysphagia (1), suction catheter entrapment (1), and fatal massive hemoptysis (1). At a mean follow-up of 13 months (range, 3 to 19 months) all remaining stents are functioning well with no displacement or infection. Overall results were satisfactory in pure fibrous stenoses and tracheobronchial malacia but poor in the presence of inflammation. Tracheobronchial wire stents can be successfully used in selected patients.
