On CT images obtained within 2\u20133 days postoperatively, the depth of pleural effusion, pneumothorax rate, lung re-expansion ratio, and maximum subcutaneous air thickness were measured. The primary outcome was the occurrence of Clavien-Dindo grade \u2265II complications within 30 days. Univariate and multivariate logistic regression analyses were performed, and predictive performance was evaluated using the area under the curve (AUC).RESULTS: Major complications occurred in 42 patients (18.2%). Multivariate analysis identified depth of pleural effusion (odds ratio [OR] = 1.213, 95% confidence interval [CI]: 1.107\u20131.329, p &lt; 0.001), pneumothorax rate (OR = 1.201, 95% CI: 1.081\u20131.333, p &lt; 0.001), lung re-expansion ratio (OR = 0.872, 95% CI: 0.809\u20130.940, p &lt; 0.001), and maximum subcutaneous air thickness (OR = 1.438, 95% CI: 1.248\u20131.656, p &lt; 0.001) as independent predictors. Receiver operating characteristic (ROC) analysis demonstrated that maximum subcutaneous air thickness had the highest predictive performance (AUC = 0.850), followed by pneumothorax rate (AUC = 0.831), lung re-expansion ratio (AUC = 0.785), and depth of pleural effusion (AUC = 0.783). CONCLUSIONS: Quantitative indices derived from early postoperative CT scans may serve as reliable imaging biomarkers for predicting major complications after pulmonary segmentectomy, thereby facilitating early identification of high-risk patients and guiding individualized postoperative management.<\/jats:p>","DOI":"10.62713\/aic.4569","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T08:34:09Z","timestamp":1781080449000},"source":"Crossref","is-referenced-by-count":0,"title":["Predictive Value of Early Postoperative CT Imaging Parameters for Major Complications Following Thoracoscopic Segmentectomy"],"prefix":"10.62713","volume":"97","author":[{"given":"Wei","family":"Jiang","sequence":"first","affiliation":[{"name":"Department of Radiology, The First People\u2019s Hospital of Jiashan, 314100 Jiaxing, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Radiology, The First People\u2019s Hospital of Jiashan, 314100 Jiaxing, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Radiology, The First People\u2019s Hospital of Jiashan, 314100 Jiaxing, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"48935","published-online":{"date-parts":[[2026,6,10]]},"container-title":["Annali Italiani di Chirurgia"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.annaliitalianidichirurgia.it\/journal\/AIC\/97\/6\/10.62713\/aic.4569","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T03:53:15Z","timestamp":1783309995000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.annaliitalianidichirurgia.it\/journal\/AIC\/97\/6\/10.62713\/aic.4569"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,10]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2026]]}},"alternative-id":["S0003-469X(26)00115-0"],"URL":"https:\/\/doi.org\/10.62713\/aic.4569","relation":{},"ISSN":["0003-469X","2239-253X"],"issn-type":[{"value":"0003-469X","type":"print"},{"value":"2239-253X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,10]]},"article-number":"1104"}}
