Patient, lesion and procedural factors associated with chest drain insertion were assessed with univariate and multivariate analyses. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> A total of 102 patients underwent aspiration for a pneumothorax following CT-PTLB. Overall, 81 patients (79.4%) had a successful pneumothorax aspiration and were discharged home on the same day. In 21 patients (20.6%), the pneumothorax continued to increase post-aspiration and required chest drain insertion with hospital admission. Significant risk factors requiring chest drain insertion included upper\/middle lobe biopsy location [odds ratio (OR) 6.46; 95%\u2009CI 1.77\u201323.65, p = 0.003], supine biopsy position (OR 7.06; 95%\u2009CI 2.24\u201322.21, p &lt; 0.001), emphysema (OR 3.13; 95%\u2009CI 1.10\u20138.87, p = 0.028), greater needle depth \u22652\u2009cm (OR 4.00; 95%\u2009CI 1.44\u201311.07, p = 0.005) and a larger pneumothorax (axial depth \u22653\u2009cm) (OR 16.00; 95%\u2009CI 4.76\u201353.83, p &lt; 0.001). On multivariate analysis, larger pneumothorax size and supine position during biopsy remained significant for chest drain insertion. Aspiration of a larger pneumothorax (radial depths \u22653\u2009cm and \u22654\u2009cm) had a 50% rate of success. Aspiration of a smaller pneumothorax (radial depth 2\u20133\u2009cm and &lt;2\u2009cm) had an 82.6% and 100% rate of success, respectively. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> Aspiration of pneumothorax after CT-PTLB can help reduce chest drain insertion in approximately 50% of patients with larger pneumothoraces and even more so with smaller pneumothoraces (&gt;80%). <\/jats:p><\/jats:sec><jats:sec><jats:title>Advances in knowledge:<\/jats:title><jats:p> Aspiration of pneumothoraces up to 3\u2009cm was often associated with avoiding chest drain insertion and allowing for earlier discharge. <\/jats:p><\/jats:sec>","DOI":"10.1259\/bjr.20220366","type":"journal-article","created":{"date-parts":[[2023,7,2]],"date-time":"2023-07-02T11:49:40Z","timestamp":1688298580000},"source":"Crossref","is-referenced-by-count":11,"title":["Manual aspiration of a pneumothorax after CT-guided lung biopsy: outcomes and risk factors"],"prefix":"10.1093","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6120-562X","authenticated-orcid":false,"given":"Michael Vinchill","family":"Chan","sequence":"first","affiliation":[{"name":"Department of Medical Imaging, University Health Network, University of Toronto, Toronto, Canada"},{"name":"Department of Radiology, Concord Repatriation General Hospital, NSW, Concord, NSW, Australia"},{"name":"Concord Hospital Clinical School, University of Sydney, NSW, Concord, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Afraz","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, University Health Network, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ya Ruth","family":"Huo","sequence":"additional","affiliation":[{"name":"Department of Radiology, Concord Repatriation General Hospital, NSW, Concord, NSW, Australia"},{"name":"Concord Hospital Clinical School, University of Sydney, NSW, Concord, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja","family":"Kandel","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, University Health Network, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrik","family":"Rogalla","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, University Health Network, University of Toronto, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","reference":[{"key":"b1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2010.01.011"},{"key":"b2","doi-asserted-by":"publisher","DOI":"10.1136\/thorax.58.11.920"},{"key":"b3","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-017-1658-5"},{"key":"b4","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-019-02196-8"},{"key":"b5","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.20190866"},{"key":"b6","doi-asserted-by":"publisher","DOI":"10.3109\/02841850903232707"},{"key":"b7","first-page":"183","volume":"46","author":"Faruqi S","year":"2004","journal-title":"INDIAN J CHEST Dis ALLIED Sci"},{"key":"b8","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-015-1167-3"},{"key":"b9","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.10.6324"},{"key":"b10","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.200.3.8756917"},{"key":"b11","doi-asserted-by":"publisher","DOI":"10.1186\/s12931-019-1049-3"},{"key":"b12","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-015-3601-y"},{"key":"b13","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.11103506"}],"container-title":["The British Journal of Radiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.birpublications.org\/doi\/pdf\/10.1259\/bjr.20220366","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T16:44:41Z","timestamp":1705077881000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/bjr\/article\/7469142"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,8]]},"references-count":13,"journal-issue":{"issue":"1148","published-print":{"date-parts":[[2023,8]]}},"alternative-id":["10.1259\/bjr.20220366"],"URL":"https:\/\/doi.org\/10.1259\/bjr.20220366","relation":{},"ISSN":["0007-1285","1748-880X"],"issn-type":[{"value":"0007-1285","type":"print"},{"value":"1748-880X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,8]]},"article-number":"20220366"}}
