Abstract
PURPOSE-To assess the safety and long-term efficacy of balloon dilation in the treatment of benign tracheobronchial stenosis. MATERIALS AND METHODS-Balloon dilation was performed under fluoroscopic guidance in 59 consecutive patients with benign tracheobronchial stenosis. Most patients had tuberculosis (48 of 59, 81%). Two to three serial balloon insufflations were performed for 5–180 seconds (mean, 85 sec) with inflation pressures as high as 16 atm with use of 6–20-mm-diameter balloon catheters. Patients with clinical evidence of restenosis underwent repeat balloon dilation. Patients were followed for 12–42 months (mean, 32 mo). RESULTS-A total of 101 balloon dilation sessions were performed in 59 patients, with a range of one to four sessions per patient (mean, 1.7 sessions). Initial symptomatic improvement was achieved in 49 (83%) of the 59 patients; however, during the follow-up period, 39 (80%) of the 49 patients experienced recurrence of their symptoms. The primary patency rates at 3, 6, 9, 12, 18, 24, and 32 months were 92%, 60%, 45%, 24%, 20%, 20%, and 20%, respectively. The secondary patency rates at 3, 6, 9, 12, 18, 24, and 32 months were 92%, 87%, 75%, 43%, 43%, 43%, and 43%, respectively. Procedure-related major complications of deep mucosal laceration (n = 2) and bronchospasm (n = 1) occurred in three patients, but they experienced no subsequent problems. CONCLUSION-Although the recurrence rate is high during the long-term follow-up period, balloon dilation seems to be a safe primary treatment modality for benign tracheobronchial stenoses and has an acceptable secondary patency rate.
