However, to date the use of these valves in patients with bronchial stump has not been described.PATIENTS AND METHODS: We treated 4 patients with endobronchial valves. Three had pneumothorax and the fourth case was a patient with a bronchial stump fistula which could not be solved with glue and silver nitrate. All four cases were men with a mean-age of 74(67-78)years.RESULTSThe four patients received 6 valves. The first patient presented bilateral tension pneumothorax after heart surgery and was treated with several chest tubes, pleurodesis and surgical procedures, all of which were unsuccessful. He was finally treated with two valves, solving the persistent air-leak. Two patients presented spontaneous pneumothorax, but due to comorbidities surgery was contraindicated. The fourth patient had a bronchial stump after lobectomy due to lung cancer and refused a new intervention involving thoracostomy. This last patient was treated with sealant twice and several times with silver nitrate without success. Finally, the patient was treated with a 7 mm valve, achieving complete stoppage of the air leak. All the patients improved within 24-hours of the procedure and were discharged in the following 6(2-710) days without no complications related to the intervention after a 6-month follow up(6-24).CONCLUSION: The use of endobronchial valves in patients with spontaneous pneumothorax with high-risk for intervention or after surgery, as well as in cases of bronchial stump after lobectomy is a safe and effective alternative to solve air leakage.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/44/Suppl_58/P486}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
