Background: Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbidity and mortality. Placental histopathology reflects the severity of uteroplacental insufficiency; however, lack of standardized reporting limits its clinical utility.
Aim
To evaluate placental histopathological changes in hypertensive disorders of pregnancy using a structured scoring system and correlate these findings with fetal outcomes.
Materials and Methods
This cross-sectional observational study included 214 placentae, comprising 107 normotensive and 107 hypertensive pregnancies, collected over two years at a tertiary care centre in Hyderabad. Placentae were examined grossly and microscopically using hematoxylin and eosin staining. A semi-quantitative scoring system assessed fibrin deposition, maternal floor infarction, syncytial knots, calcification, and villous basement membrane thickening. Statistical analysis was performed using SPSS v27.
Results
Placentae from hypertensive pregnancies showed significantly higher histopathological scores compared to normotensive controls (p < 0.05). Increased syncytial knots and fibrin deposition were the most frequent lesions. Higher lesion scores correlated significantly with prematurity, low birth weight, increased NICU admissions, and stillbirths, particularly in severe pre-eclampsia and eclampsia.
Conclusion
A structured histopathological scoring system provides an objective and reproducible method for placental reporting in hypertensive disorders of pregnancy and demonstrates strong correlation with adverse fetal outcomes.
