Correlation Of Placental Changes With Fetal And Maternal Outcome In Mothers With Hypertensive Disorders Of Pregnancy

Abstract

Hypertension represents one of the most prevalent complications encountered during pregnancy, significantly contributing to both maternal and perinatal morbidity and mortality. The placenta, acting as a crucial feto-maternal organ, plays a pivotal role in sustaining pregnancy and fostering the healthy development of the fetus. Notably, the weight of the placenta holds functional importance, as it correlates with the villous surface area and fetal metabolism. Motivated by this context, the present study endeavors to examine the morphological and histological alterations in the placenta associated with hypertensive disorders of pregnancy and to assess their correlation with maternal and fetal outcomes. Methods: A prospective investigation encompassing 120 cases was conducted, comprising 60 normotensive mothers (Group A) and 60 mothers with hypertensive disorders of pregnancy (Group B). Placental specimens obtained from these participants were subjected to morphological and histological analyses, with subsequent correlation with maternal and fetal outcomes. Results: Our findings revealed a notable reduction in placental weight and dimensions within Group B compared to Group A. Histopathological examination unveiled a significant increase in the incidence of syncytial knots, fibrinoid necrosis, hyalinization, and calcification in placentas from the hypertensive group, directly correlating with neonatal complications. Furthermore, the mean neonatal birth weight was significantly higher in Group A compared to Group B. Conclusion: Hypertensive disorders of pregnancy exert a substantial impact on placental morphology, leading to diminished weight and dimensions, indicative of placental insufficiency attributable to compromised utero-placental blood flow. These alterations ultimately influence neonatal weight and overall neonatal outcomes. Our study underscores the presence of distinct morphological changes in the placenta that detrimentally affect fetal growth.
