Macroand micromorphological characteristics of placenta in physiological pregnancy and in COVID-19 at different stages of pregnancy

Abstract

Our article presents the macro- and micromorphological characteristics of placenta during physiological pregnancy and COVID-19 according to domestic and foreign literature. A search was made for foreign and domestic scientific publications on the morphological assessment of the placentas of healthy pregnant women and women with a confirmed diagnosis of COVID-19 (positive PCR test for SARS-CoV-2 virus). In connection to the pandemic caused by a novel coronavirus infection, the study of the pregnancy and search for specific changes in women with a confirmed diagnosis of COVID-19 is of great interest among scientists around the world. Recent scientific publications focused mostly on nonspecific changes and signs of maternal and fetal vascular malperfusion. We reviewed publications, scientific articles, dissertations, literary reviews on E-library, Pubmed, Cyberleninka with access to the full text, whereas publications with paid access or only were omitted.
