We assessed factors including pulmonary function tests, bronchoalveolar lavage (BAL), blood tests, and imaging and to see if any of them caused an increased risk of iatrogenic pneumothorax.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n 19 patients suffered a pneumothorax (25%). Neutrophilia on BAL (37.9% pneumothorax when present vs 12.8% when not present,\n p<\/jats:italic>\n = 0.046) and the presence of ground glass opacification on high resolution CT-Thorax (38.2% vs 12.5%,\n p<\/jats:italic>\n = 0.014) increased the risk of pneumothorax during TBLC. Other factors such as the presence of pleura in the biopsy sample (47.1% vs 17.2%,\n p<\/jats:italic>\n = 0.021), as well as taking 3 or more biopsies (35.7% vs 11.8%,\n p<\/jats:italic>\n = 0.019) were also significant predictors of pneumothorax.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Markers of acute inflammation as well as increased number of biopsies taken in a procedure lead to increased risk of pneumothorax. This may lead to changes in planning, patient selection and timing of TBLC procedures in ILD patients.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/14799731251383492","type":"journal-article","created":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T10:47:24Z","timestamp":1761043644000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Risk factors for pneumothorax in patients with interstitial lung disease undergoing transbronchial lung cryobiopsy, a research letter"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0155-2072","authenticated-orcid":false,"given":"Sean","family":"Landers","sequence":"first","affiliation":[{"name":"Cork University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliette","family":"Morrow","sequence":"additional","affiliation":[{"name":"Cork University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"McCarthy","sequence":"additional","affiliation":[{"name":"Cork University Hospital"},{"name":"University College Cork"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8858-2938","authenticated-orcid":false,"given":"Michael T.","family":"Henry","sequence":"additional","affiliation":[{"name":"Cork University Hospital"},{"name":"University College Cork"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,10,21]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.00425-2022"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0280-2021"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/LBR.0000000000000865"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/LBR.0000000000001023"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00408-021-00424-y"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12890-021-01551-1"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2022.106922"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0049125"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.21037\/jtd-21-1851"}],"container-title":["Chronic Respiratory Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/14799731251383492","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/14799731251383492","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/14799731251383492","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T16:48:26Z","timestamp":1777394906000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/14799731251383492"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9]]},"references-count":9,"alternative-id":["10.1177\/14799731251383492"],"URL":"https:\/\/doi.org\/10.1177\/14799731251383492","relation":{},"ISSN":["1479-9731","1479-9731"],"issn-type":[{"value":"1479-9731","type":"print"},{"value":"1479-9731","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,9]]},"article-number":"14799731251383492"}}
