Risk of pneumothorax caused by computerized tomography-guided percutaneous core needle biopsy of the lung in elderly and young patients

Context: The incidences and risk factors caused by computed tomography (CT)-guided percutaneous computed tomography-guided needle biopsies (PCNBs) in elderly and young patients were not very clear. Aims: This study explored the different incidences of pneumothorax caused by PCNBs and related risk factors in elderly and young patients. Settings and Design: The medical records of 1100 patients who underwent CT-guided PCNBs in a hospital from January 2018 to December 2019 were retrospectively reviewed. Subjects and Methods: Data relating to the patients, lesions, techniques, and diagnoses were collected according to the ethical standards of the institutional research committee (registration number: KYLL-202008-145). Statistical Analysis Used: The variables were significant by univariate analysis and further analyzed by multivariate logistic regression analysis. Results: In the 1100 patients with PCNBs, the incidence of pneumothorax in groups ≥65 years old and
