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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Peripheral artery disease narrows the vessels that carry blood to the legs, and surgery to restore flow does not always go well. Researchers at Fudan University are studying whether CT perfusion, a scan that measures blood flow in tiny vessels, can help predict which patients will face death, amputation, or other serious problems after revascularization. The study follows about 200 adults with PAD for up to two years, using routine scans and medical records. No experimental drugs or devices are involved.

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 the approach works, doctors could spot high-risk patients earlier and tailor treatment decisions after surgery to restore blood flow.
What could go wrong
This is an observational study, so it can show a link between imaging and outcomes but cannot prove cause and effect. The results may not apply to all PAD patients or hospitals.

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

Expected to start

Nov 2026

An estimate. Start dates often move.

Expected to finish

Nov 2029

An estimate. End dates often move.

Lead sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study will enroll adult patients diagnosed with peripheral artery disease (PAD) who are scheduled to undergo vascular reconstruction (endovascular or surgical). Participants will receive CT perfusion imaging prior to the procedure. The study population aims to investigate the predictive value of CT perfusion parameters for postoperative adverse clinical events, with a planned follow-up period of 2 years.

Ages

18 years and older

Anyone

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

Inclusion Criteria: * Diagnosis of peripheral artery disease (PAD) confirmed by clinical evaluation and imaging (e.g., CTA, DSA). * Planned to undergo endovascular or surgical revascularization. * Age ≥ 18 years old. * Signed written informed consent. Exclusion Criteria: * Allergy to iodinated contrast agents. * Severe renal insufficiency (e.g., eGFR \< 30 mL/min/1.73m²). * Acute limb ischemia requiring emergency surgery. * Major limb amputation already performed prior to enrollment. * Life expectancy less than 2 years due to severe comorbidities. * Unwilling or unable to complete the 2-year follow-up.
