Amplatzer Occluders for Effective Nonsurgical Management of Bronchopleural Fistulae

Abstract

Background: To assess the safety and efficacy of bronchopleural fistulae closure with Amplatzer occluder devices (AGA Medical, Golden Valley, MN) through our experience of over 14 years.

Methods: Retrospective data review of patients from Rabin Medical Center who underwent Amplatzer occluder device placement between March 2007 and September 2021 for bronchopleural fistulae closure.

Results: In total, 72 patients had 83 Amplatzer occluder devices implanted for bronchopleural fistulae closure. The median age was 65.5 (interquartile range 56.0-72.3) years. The primary diseases were lung malignancy (48 [66.7%]) and thoracic infection (9 [12.5%]). Bronchopleural fistulae developed mainly following pneumonectomy (40.3%) and lobectomy (33.3%), with a median time from surgery to Amplatzer placement of 3.9 (interquartile range 1.4-16.4) months. We encountered no procedural or immediate postprocedural complications or deaths. Six months after Amplatzer insertion, there were 7 (8.4%) Amplatzer removals and 11 (15.3%) fistula-related deaths.

Conclusions: Amplatzer occluders are a safe modality for nonsurgical bronchopleural fistulae management with ease of placement under moderate sedation and flexible bronchoscopy with good short- and long-term effectivity.
