[Experience of Treatment for Pneumothorax with Coronavirus Disease 2019( COVID-19) Pneumonia].

A 73 years old male patient with the past history of kidney transplantation was admitted to our hospital for treatment of coronavirus disease 2019 (COVID-19) pneumonia. On the 25th day after the onset of symptoms when his condition was improving, he suddenly developed pneumothorax. Chest tube drainage was performed and connected the tube to the drainage device using a high efficiency particulate air (HEPA) filter. Because of the improvement of infection, the HEPA filter was removed from the drainage device on day 28. Chest tube drainage was continued by day 35, and he was discharged and introduced home oxygen therapy on day 51.
