INTRODUCTION/CONTEXT: Hypertensive disorders of pregnancy (HDP) are major complications of pregnancy and seen in about 5% to 10% of all pregnancies. Among these, pre-eclampsia is a leading cause of perinatal and fetal morbidity and mortality. It is a multifactorial and multisystemic disorder that results in a variety of histomorphologic features, some of which may be missed if a diligent examination is not performed.
AIMS AND OBJECTIVES: The present study aimed to propose a checklist and novel scoring system to ensure comprehensive placental examination. We also aimed to evaluate the correlation, if any, between histopathological and morphometric findings in HDP and with fetal growth.
MATERIALS AND METHODS: A total of 100 placentas of women diagnosed with hypertensive disorders of pregnancy were included in our cross-sectional, observational study. Morphometric features and histological features that are known to be seen in HDP were analyzed, and each of them was given a numerical score based on their severity.
STATISTICAL ANALYSIS USED: Pearson correlation coefficient test was applied to correlate these findings, and ANOVA test was used to assess the correlation of these findings with fetal growth restriction (FGR).
RESULTS: More than 50% of the placentas studied recorded maximum scores for weight and volume. At least 25% of the placentas showed the presence of all histo-pathological features under study. The association of total morphometric and histological scores was not found to be statistically significant (P-value = 0.239). We found a significant difference between means of morphometric scores of cases with normal fetal growth and cases showing FGR (P-value = 0.008).
CONCLUSION: Uneven distribution and presentation of the lesions in these cases may lead to the absence of correlation between morphometry and histopathology, as seen in our study. Morphometric derangements in the placenta correlate with FGR. Our proposed checklist and scoring system can be utilized to standardize reporting of placental specimens in the evaluation of placentas with HDP, in order to facilitate and standardize the placental reporting.
