PURPOSE: To evaluate the effect of @entity384 and endobronchial stent placement for bronchial fibrous stenoses and @entity17593 after lung transplantation. MATERIALS AND METHODS: Bronchial dilation and/or stent placement was performed on 25 lung transplant recipients. Indications included severe @entity1353 with @entity55 (n = 24) and @entity1576 (n = 1). All @entity1 underwent pulmonary function testing (PFT) before and after bronchial dilation, the results of which were evaluated for changes. A total of 63 procedures were performed between February 1996 and December 1998. Thirty-five lesions were treated (18 were due to @entity17593 , 17 were due to @entity82 ). Areas treated included the left mainstem bronchus (n = 11), bronchus intermedius (n = 10), right mainstem bronchus (n = 7), left upper lobe bronchus (n = 4), right lower lobe bronchus (n = 2), and right middle lobe bronchus (n = 1). Bronchoscopic and/or bronchographic follow-up ranged from 1 to 34 months (mean, 15 months). RESULTS: Six-month primary patency of stents placed for @entity17593 was 71% (10 of 14), with three of the four occlusions caused by mechanical failure of Palmaz stents in the mainstem bronchi. Six-month primary patency for treatment of @entity82 was 29%. Secondary patency at 1 year was 100% for both @entity17593 and @entity82 . After treatment, there was a significant improvement in mean PFT results (P = .01-.0001). There was one acute complication, obstruction of the left lower lobe bronchus by a Wallstent treated by dilating a hole in the side of the stent. CONCLUSIONS: @entity384 and stent placement are safe and effective for bronchial strictures and @entity17593 after lung transplantation, resulting in significant improvement in PFT results. However, there is almost universal restenosis in @entity1 treated for @entity82 necessitating reintervention for prolonged patency.
