The development of the SARS‐CoV‐2 pandemic caused a common appearance of severe pulmonary complications, rarely seen as a result of the other infections. These are pneumothorax, pneumomediastinum, emphysematous bullae, cavitary lung lesions, or subcutaneous emphysema. Their formation is influenced by both—the natural course of the disease and the treatment strategy adopted.

Development of serious complications after COVID-19 infection can occur even in very young patients without any comorbidities. Appropriate, non-aggressive ventilation and adequate treatment is essential for COVID-19 convalescents and may prevent them from aggravating surgical procedures.
