Little detailed information was available on computer tomography (CT) imaging features of postoperative BPF and treating procedures with pushable Embolization Coil.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>We aimed to specify the imaging characteristics of postoperative BPFs and present our experience treating them with the pushable Embolization Coil.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Six consecutive patients (four males and two females aged 29\u201356\u2009years) diagnosed with postoperative BPF receiving bronchoscopic treatment with the pushable Nester\u00ae Embolization Coil (Cook Medical, Bloomington, Indiana) were included in this single-center, retrospective study. Multiplanar reconstruction of multidetector CT scans was reviewed for the presence, location, size, and radiological complications of each BPF, including air collection, pneumothorax, bronchiectasis, and chest tube. Using standardized data abstraction forms, demographic traits and clinical outcomes were extracted from the medical files of these patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The underlying diseases for lung resection surgery were pulmonary tuberculosis (<jats:italic>n<\/jats:italic>\u2009=\u20093), lung adenocarcinoma (<jats:italic>n<\/jats:italic>\u2009=\u20092), and pulmonary aspergillosis (<jats:italic>n<\/jats:italic>\u2009=\u20091). All patients had air or air-fluid collection with chest tubes on radiological findings. Multiplanar reconstruction identified the presence of postoperative BPF in all patients. Five fistulas were central, located proximal to the main or lobar bronchus, while one was peripheral, distant from the lobar bronchus. Fistula sizes ranged from 0.8 to 5.8\u2009mm. Subsequent bronchoscopy and occlusion testing confirmed fistula openings in the bronchial stump: right main bronchus (<jats:italic>n<\/jats:italic>\u2009=\u20091), right upper lobe (<jats:italic>n<\/jats:italic>\u2009=\u20092), and left upper lobe (<jats:italic>n<\/jats:italic>\u2009=\u20093). The angioplasty catheter-based procedure allows precise fistula occlusion \u201clike a sandwich\u201d with the pushable Embolization Coil. Five patients with BPF sizes ranging from 0.8 to 1.5\u2009mm were successfully treated with a pushable Embolization Coil, except for one with a BPF size of 5.8\u2009mm. No adverse events or complications were observed throughout follow-up, ranging from 29 to 1,307\u2009days.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The pushable Nester\u00ae Embolization Coil seems a minimally invasive, cost-effective, and relatively easy-to-perform bronchoscopic treatment for postoperative BPF with a size less than 2\u2009mm. Further studies are required to ensure the use of pushable Embolization Coil in treating postoperative BPF.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2024.1333157","type":"journal-article","created":{"date-parts":[[2024,5,13]],"date-time":"2024-05-13T04:31:30Z","timestamp":1715574690000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Case report: Endobronchial closure of postoperative bronchopleural fistula with embolization coil: a sandwich-like approach"],"prefix":"10.3389","volume":"11","author":[{"given":"Yang","family":"Bai","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Chi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hansheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yishi","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuliang","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,5,13]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"534","DOI":"10.1093\/jjco\/hyw037","article-title":"Neoadjuvant therapy and risk of bronchopleural fistula after lung cancer surgery: a systematic meta-analysis of 14 912 patients","volume":"46","author":"Li","year":"2016","journal-title":"Jpn J Clin Oncol"},{"key":"ref2","first-page":"462","article-title":"Fistules bronchiques apr\u00e8s pneumonectomies","volume-title":"Appareil Respiratoire, Mediastin, Paroi Thoracique","author":"Le Brigand","year":"1973"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"1456","DOI":"10.1016\/S0022-5223(19)34643-4","article-title":"Bronchopleural fistulas associated with lung cancer operations.
