Reversibility of total airway closure and alveolar consolidation in a COVID-19 patient: A case study.

Coronavirus disease 2019 (COVID-19) may be complicated by life-threatening pneumonia requiring tracheal intubation, mechanical ventilation and veno-venous extracorporeal membrane oxygenation (vvECMO). It is not yet clear to what extent and after which delay the most severe cases of COVID-19 pneumonia are reversible. Here, we present a 39-year-old patient who developed a severe COVID-19-attributed acute respiratory distress syndrome (ARDS) resulting in complete alveolar consolidation and airway closure for several weeks.
