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
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 This study
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 Results may not be published yet.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

Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a special 3D X-ray done in the operating room can replace standard CT scans after repairing an abdominal aortic aneurysm. 427 patients were randomly assigned to either the new 3D scan or the usual approach. The goal was to see if the new method reduces radiation exposure, uses less contrast dye, and helps fix problems during the same surgery, avoiding a second procedure.

What this could mean

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

Active substance
3D rotational angiography (imaging technique)
What this could lead to
If successful, this approach could reduce patients' radiation exposure and the need for repeat procedures after aneurysm repair.
What could go wrong
This is a single-center study, and the technique may not detect complications as well as standard CT scans. Results may not apply to all hospitals or patients.
