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 Results may not be published yet.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.

Summary

This study is testing a device called Laser Speckle Contrast Imaging (LSCI) that uses a laser to measure blood flow in the leg. The goal is to see if it can help doctors monitor blood flow before, during, and after surgery to restore circulation. The study will enroll 30 people scheduled for leg revascularization surgery. Researchers will compare the LSCI readings with standard temperature measurements and another imaging method.

What this could mean

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

Active substance
Laser Speckle Contrast Imaging device
What this could lead to
If successful, this could give surgeons a new, non-invasive way to monitor blood flow in real time during leg surgery, potentially improving outcomes.
What could go wrong
This is a small, early feasibility study with only 30 participants. The device may not prove reliable or useful enough to change current practice.

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 population of this study will undergo a revascularization of the lower extremity due to peripheral artery disease. Such revascularization can be thrombo-endarterectomy (TEA), or endovascular percutaneous transluminal angioplasty (PTA).

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Scheduled for lower-extremity revascularization * Undergoing pre- and postoperative indocyanine near-infrared fluorescence perfusion measurements Exclusion Criteria: Any condition that the investigator considers to be potentially jeopardizing the patient's wellbeing or the study objectives
