The first reported use of autologous blood pleurodesis for treatment of prolonged air leak in COVID-19-related spontaneous pneumomediastinum and pneumothorax: A case report

Abstract

Spontaneous pneumomediastinum (SPM) and pneumothorax (PTX) have been described as rare complications of COVID-19 pneumonia. We present a case of COVID-19 pneumonia which was complicated by SPM on Day 13 of admission with progression to spontaneous PTX 2 days later which necessitated intercostal chest drainage. It was complicated by prolonged air leak (PAL) for the next 9 days despite being on continued low-dose suction and another additional larger bore intercostal drain inserted. Surgical pleurodesis was not an option in view of anaesthesia and operative risk expected in COVID-19. In view of this, autologous blood pleurodesis (ABP) to address the alveolar pleural leak was opted. ABP has been previously used for PAL in cases of non-COVID-19-related intractable spontaneous PTX. The air leak ceased with subsequent lung re-expansion, with good clinical and radiological improvement. He was discharged well after resolution of PTX which required intercostal drain for a total of 15 days.
