MICROCIRCULATION DISTURBANCES IN POST-COVIDED PATIENTS WITH TROPHIC ULCERS OF THE MUCOSA OF THE ORAL CAVITY

Abstract

Currently, the COVID-19 infection caused by coronavirus SARS-CoV-2, poses the greatest danger to life and health of mankind. The Covid 19 pandemic, which has affected more than 400 million people in the world, about 20-30% of patients have experienced the acute phase of COVID-19, do not fully recover and continue to experience post-COVID syndrome (PCS) lasting up to one year. One of these symptoms is the appearance of trophic ulcers on the oral mucosa (OM). One of the likely mechanisms for the development of trophic ulcers in the oral cavity is damage to the endothelium of the capillary bed, which leads to disruption of the microcirculation of blood and lymphatic vessels [2,3,5].

An important non-invasive method for diagnosing the state of capillary blood flow in trophic ulcers of the oral mucosa in patients with a history of Covid 19 is the determination of the microcirculation of tissue vessels [1,4,6].
