Treatment of malignant or benign tracheobronchial stenosis by home made Nitrol stents

Objective: To evaluate the therapeutic effects of home made Nitrol stents in the treatment of malignant or benign tracheobronchial stenosis. Methods: Thirteen patients with malignant or benign tracheobronchial stenosis were treated by Nitrol stents. The stenosed sites located in trachea in 5, tracheo-bronchi in 6, main bronchus in 2. All cases were malignant except one was benign. Results: 15 stents were successfully placed the expected position with dyspnea rapidly improved. The average survival time was 11.4 months. Conclusions: It is an effective way to place Nitrol stent in treatment of tracheobronchial stenosis under x-ray guidance with fiber tracheo-bronchoscopy
