Placental Histopathological Changes In Covid-19 And Their Associated Effects On Adverse Pregnancy Outcomes, Eric Mugambi

Master of Medicine in Obstetrics and Gynecology

Introduction: Coronavirus disease (COVID-19) is a significant cause of morbidity and mortality among pregnant women. Pregnant women infected with SARS-CoV-2 are at a greater risk of pre-eclampsia/eclampsia, non-iatrogenic preterm birth, stillbirth, and small for gestational age infants/fetal growth restriction (SGA/FGR), which share a common placental etiology. Placental histopathological changes attributed to COVID-19 have been demonstrated but there is a knowledge gap in how these changes impact pregnancy outcomes particularly those of placental origin. Objectives: To investigate if there is an association between placental histopathology (maternal vascular malperfusion (MVM), fetal vascular malperfusion (FVM), acute and chronic inflammatory pathology, and other findings …
