In asymptomatic post-COVID-19 patients undergoing surgery, the severity of SARS-CoV-2 infection in terms of hospitalization, need for mechanical ventilation, the clinical course of pneumonia, and the need for vasoactive drugs, is associated with an increase of pulmonary pathological findings determined by LUS. Nevertheless, the incidence of PPC could correspond to that described in the pre-pandemic stage.
