PATHOMORPHOLOGICAL CHARACTERISTICS OF COVID-19

Abstract

It is known that the role of the placenta in physiological and pathological pregnancy is unique and connects the fetus and the mother's organism together. As a result of the placenta's inappropriate development during the period of pregnancy or, on the contrary, its function is disturbed under the influence of various factors, it leads to a significant change in the development of the fetus. In 85-90% of cases, infertility is caused by placental insufficiency, i.e. placental uterine blood circulation disorder. In addition, under the influence of viral diseases, special pathomorphological changes in the placenta are observed: lympho-plasmacytic infiltration in the stroma of the teats, hemocidrin bodies in the stroma of blood vessels and teats, necrosis of the teats, focal or diffuse villusitis and intervillusitis.
