Spontaneous pneumomediastinum, pneumothorax, pneumoperitoneum and soft tissue emphysema as complication in patients with COVID-19, series of cases

Abstract

Spontaneous pneumomediastinum, pneumothorax, pneumoperitoneum, and soft tissue emphysema have been recently described in several sources as possible complications in patients with severe COVID-19 and lung damage. This clinical case is dedicated to demonstrarte the development of these lesions in 3 male patients with comorbid conditions. The putative pathophysiological mechanism of these complications is air leakage due to extensive diffuse alveolar damage followed by rupture of the alveoli. All presented patients had a favorable outcome of the disease without lethal cases, their laboratory data and clinical dynamics were described.It should be noted that such conditions are not rare complications of COVID-19, and are observed mainly in male patients with severe form of the disease and the presence of comorbid conditions. Such complications are associated with long hospitalization and a severe prognosis. In some cases, with a mild course of the disease and positive dynamics in a decrease of the percentage of pulmonary lesions, the outcome is favorable, not requiring additional invasive interventions.
