Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Placenta accreta spectrum is a serious pregnancy complication where the placenta grows too deeply into the uterus, risking severe bleeding during delivery. Doctors usually rely on ultrasound to detect it, but ultrasound accuracy varies. This study checks whether simple blood tests taken on hospital admission can help predict which mothers with placenta previa and a prior cesarean delivery will develop the condition. Researchers compare blood test results with the actual diagnosis confirmed at delivery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If the blood markers prove reliable, doctors could use a routine blood test alongside ultrasound to flag high-risk pregnancies earlier and plan safer deliveries.
What could go wrong
This is an observational study, so it can only show whether markers correlate with placenta accreta, not whether acting on them improves outcomes. The findings may not hold up in other hospitals or patient groups.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of pregnant women aged 18 to 40 years presenting to the Women's Health Hospital at Assiut University. Eligible participants must have a singleton pregnancy at a gestational age greater than 28 weeks, a diagnosis of placenta previa confirmed by ultrasound, a history of previous cesarean delivery, and be hemodynamically stable upon admission. Patients will be excluded if they present with intrauterine fetal demise (IUFD), intrauterine growth restriction (IUGR), premature rupture of membranes (PROM), chorioamnionitis, known blood diseases or bleeding tendencies, hypertension, or diabetes mellitus.

Ages
