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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tests a new 3D ultrasound imaging method to map blood vessels in the heart and brain of people with atherosclerosis who are scheduled for carotid surgery. The goal is to see if this non-invasive, radiation-free technique can detect blockages and incomplete vessel networks as well as standard CT or MRI scans. Thirty-seven participants will receive an ultrasound contrast agent and undergo imaging before their surgery.

What this could mean

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

Active substance
SonoVue® (ultrasound contrast agent)
What this could lead to
If successful, this could provide a safer, non-invasive way to map blood vessels in the heart and brain, helping prevent complications during surgery.
What could go wrong
This is a small, early-stage study with only 37 participants, so results may not apply to everyone. The imaging technique is still experimental and may not be as accurate as standard methods.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 37 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with asymptomatic carotid stenosis, without recent stroke, and scheduled for carotid endarterectomy within the next 30 days. * Age ≥ 18 years. * Beneficiary of a social security system or equivalent coverage. * Signed informed consent. * Patients already enrolled in another biomedical research study may also participate in this study. Exclusion Criteria: * Contraindication to the use of the ultrasound contrast agent SonoVue®: known hypersensitivity to the active substance or to any of the following excipients: Macrogol 4000; Distearoylphosphatidylcholine; Sodium dipalmitoylphosphatidylglycerol; Palmitic acid. * Allergy to ultrasound gel. * Refusal or inability (linguistic or psychological) to sign the informed consent form. * Subject to legal protection measures, such as guardianship (in accordance with Article L1122-2 of the French Public Health Code). * Pregnant or breastfeeding women cannot participate in this study.
