What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Placenta accreta spectrum happens when the placenta grows too deeply into the uterus, which can cause dangerous bleeding during delivery. Doctors struggle to predict how severe each case will be before surgery. This study measures a new ultrasound angle, the placenta-cervical interface angle, in 100 pregnant women who have placenta previa or suspected accreta. Researchers check whether that angle matches how severe the condition turns out to be and whether it relates to blood loss and newborn health.

What this could mean

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

Active substance
transvaginal ultrasound measurement of the placenta-cervical interface angle
What this could lead to
If the angle proves accurate, doctors could use a routine ultrasound measurement to flag severe placenta accreta before delivery and plan surgery with the right team and blood supplies ready.
What could go wrong
This is a single-center observational study of 100 pregnancies, so the angle may not predict outcomes reliably in other hospitals or with different ultrasound operators. The measurement itself carries no physical risk, but a missed or wrong prediction could mislead delivery planning.
