What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study investigates whether measuring the thickness of the carotid artery (a major artery in the neck) before surgery can help predict blood pressure swings and complications during liver transplant operations. Researchers will measure carotid artery thickness using a simple, non-invasive ultrasound in 54 adults scheduled for a liver transplant. They will then track how blood pressure and the need for medications to support blood pressure change during surgery. The goal is to see if this quick scan can identify patients who need extra monitoring or proactive treatment to keep their blood pressure stable during the procedure.

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 successful, this could help doctors identify high-risk liver transplant patients before surgery and tailor their care to reduce complications.
What could go wrong
This is a small, observational study, so it can only suggest a link, not prove cause and effect. The findings may not apply to all liver transplant patients.
