Fetal fornix and hippocampus measurements in early-onset preeclampsia pregnancies

Evaluation of the Fetal Fornix and Hippocampus in Pregnant Women With Early-Onset Preeclampsia

Not applicable Interventional Ankara Etlik City Hospital · NCT07245056

This project will see if fetuses of pregnant women with early-onset preeclampsia have smaller fornix and hippocampus measurements than fetuses of healthy pregnancies.

What this trial studies

This single-center observational study will use fetal imaging to measure fornix and hippocampus dimensions between 20 and 34 weeks' gestation in pregnancies complicated by early-onset preeclampsia and in matched healthy controls. Women meeting inclusion criteria (age 18–45, singleton pregnancy, EOPE) will undergo standardized fetal brain measurements while those with specified comorbidities or fetal anomalies will be excluded. Measurements will be compared between groups to identify differences in hippocampal and fornix size that may reflect altered fetal brain development. The protocol is conducted at a single site with predefined measurement and analysis methods to minimize variability.

Who should consider this trial

Good fit: Pregnant women aged 18–45 with singleton pregnancies between 20 and 34 weeks' gestation who have a diagnosis of early-onset preeclampsia are the ideal candidates.

Not a fit: Women with multiple pregnancies, chronic medical conditions, fetal congenital or chromosomal anomalies, chronic medication use, tobacco or alcohol use during pregnancy, or those with late-onset preeclampsia (≥34 weeks) are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If results show reduced fetal fornix or hippocampus dimensions in EOPE, it could help identify fetuses at higher risk for later neurodevelopmental issues and guide closer postnatal follow-up.

How similar studies have performed: Prior research links preeclampsia to altered neurodevelopment in offspring, but no studies have specifically measured fetal fornix and hippocampus in early-onset preeclampsia, making this a novel approach.
