Methods: A retrospective single-center analysis of percutaneous computed tomography (CT)-guided transthoracic lung biopsies was performed between 2017 and 2022. After excluding the patients who received an ultrasound-guided biopsy, combined lung biopsy with ablation, fiducial placement, unsuccessful procedure due to uncooperative patient, and age under 18 years, 884 patients\u2019 clinical information was collected (667 without track embolization and 217 with track embolization). The incidence of early and late pneumothorax and chest tube placement were compared between the two groups. Propensity score matching (PSM) was applied to minimize selection bias. Univariable and multivariable analyses were performed to determine risk factors for pneumothorax. Results: After PSM, the baseline differences and all factors that could affect the incidence of pneumothorax were balanced between the track embolization group (217 patients) and the non-track embolization group (217 patients). The incidence rates of early pneumothorax (13.4% vs. 24.0% p = 0.005), late pneumothorax (11.0% vs. 18.0% p = 0.021), and chest tube placement (0.9% vs. 4.6% p = 0.036) were significantly decreased in the track embolization group. However, the success rate of tissue diagnosis yield and length of hospital stay were not significantly different between the two groups. In multivariate analysis, the risk of pneumothorax increased as the fissure was passed (OR = 3.719, p = 0.027). Conclusions: Using track embolization with a gelatin sponge torpedo significantly decreased the incidence of pneumothorax and chest tube placement following percutaneous CT-guided lung biopsy.<\/jats:p>","DOI":"10.3390\/jcm13164666","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T07:59:07Z","timestamp":1723190347000},"page":"4666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Reduced Incidence of Pneumothorax and Chest Tube Placement following Transthoracic CT-Guided Lung Biopsy with Gelatin Sponge Torpedo Track Embolization: A Propensity Score\u2013Matched Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1491-3292","authenticated-orcid":false,"given":"Sasikorn","family":"Feinggumloon","sequence":"first","affiliation":[{"name":"Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panupong","family":"Radchauppanone","sequence":"additional","affiliation":[{"name":"Chiangrai Prachanukroh Hospital, Chiang Rai 57000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanapong","family":"Panpikoon","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chinnarat","family":"Buangam","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaewpitcha","family":"Pichitpichatkul","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9719-5817","authenticated-orcid":false,"given":"Tharintorn","family":"Treesit","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Therapeutic Radiology, Faculty of Medicine, Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"920","DOI":"10.1136\/thorax.58.11.920","article-title":"Guidelines for radiologically guided lung biopsy","volume":"58","author":"Manhire","year":"2003","journal-title":"Thorax"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e43","DOI":"10.1016\/j.crad.2012.09.008","article-title":"CT-guided percutaneous core needle biopsy for small (\u226420 mm) pulmonary lesions","volume":"68","author":"Li","year":"2013","journal-title":"Clin.
