CAN PLACENTAL HISTOPATHOLOGICAL LESIONS BE A GUIDE TO MATERNAL AND NEONATAL OUTCOMES IN PATIENTS WITH PREECLAMPSIA?

Objective: The aim of this study was to investigate the predictive role of massive perivillous fibrinoid deposition (MPFD), syncytial knots, and accompanying histopathological features of placentas of preeclampsia (PE) on maternal and neonatal outcomes. Matherials and methods: A retrospective clinicopathological study was conducted in a tertiary unit. In the study, 51 pregnant women admitted with PD and 55 normotensive healthy pregnant women matched for age and gestational age were compared. Information regarding clinical characteristics, neonatal findings, and placental properties such as syncytial knots, vascular structure density, placental area, volume, and weight) was retrieved. Results: Massive perivillous fibrinoid deposition, syncytial knots and decreased vessels in terminal villi were significantly frequent in the PE group compared to the controls. However, these histopathological findings were not associated with clinical and neonatal outcomes. Conclusions: Syncytial knot and perivillous fibrin deposition are significant microscopic findings of preeclampsia. However, the presence and amount of fibrin deposition were not correlated with perinatal outcome.
