All
placental pathology reports in 2021-2022 at our tertiary center were reviewed
for an indication of PreE, and 52 cases were confirmed. Maternal demographic, clinical
fetal, and placental objective measures were compiled. A pathologist analyzed
specimens for evidence of lesions consistent with MVM. A score of low or high
grade MVM was assigned based on subtype frequency from a previously published
scale. Chi-square, point-biserial correlations, and logistic regression were
applied, with significance set at p< 0.05.
