The accuracy of computed tomography in detecting surgically resectable blebs or bullae in primary spontaneous pneumothorax. Clinical features of smokers with radiological emphysema but without airway limitation. B., Sanchez-Salcedo P., Bastarrika G., Campo A., Berto J., Ocon M. These results argue in favor of a systematic screening of aeric pleuro-pulmonary lesions during the initial assessment for professional divers.ĬT chest blebs bullae decompression illness diving pulmonary barotrauma pulmonary cyst spirometry.Ĭopyright © 2022 Bonnemaison, Castagna, de Maistre and Blatteau.Īlcaide A. Abnormalities with an aerial component are much less frequent, but their presence generally leads to a decision of unfitness. Conclusion: The systematic performance of thoracic CT scan in a young population free of pulmonary pathology revealed a majority of benign nodules. No association was found between the presence of nodules and the general characteristics of the population, whereas in six subjects emphysema bullae were found statistically associated with active smoking or abnormal spirometry results. Abnormalities with an aerial component accounted for 13% of the abnormal scans with six emphysema bullae, three bronchial dilatations and one cystic lesion. 76% of the abnormal scans were benign nodules, 26% of which measured 6 mm or more. We identified 25% of divers with CT scan abnormalities. 19% of the subjects had abnormal spirometry. Results: The study included 307 candidates, mostly male, with a median age of 25 years. The following data were collected: sex, age, BMI, history of respiratory pathologies and smoking, treatments, allergies, diving practice, results of spirometry, reports of thoracic CT scans, as well as fitness decision. Methods: 330 records of military diving candidates who underwent an initial assessment between October 2018 and March 2021 were analyzed, in a single-center retrospective analysis. The objective of this work was to evaluate the prevalence of the pulmonary abnormalities of the thoracic CT scan, and to relate them to the characteristics of this population and the results of the spirometry. It has been replaced since 2018 by the thoracic CT scan for military diving fitness in France. ![]() Chest radiography has long been the baseline examination for the detection of respiratory pathologies in occupational medicine. These rare accidents can have dramatic consequences. Introduction: The presence of intra-pulmonary air lesions such as cysts, blebs and emphysema bullae, predisposes to pulmonary barotrauma during pressure variations, especially during underwater diving activities.
