An observational study in Peripheral Artery Disease (PAD), CT Perfusion and Revascularization, sponsored by Fudan University. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-14.

Peripheral artery disease (PAD) affects millions worldwide and can lead to serious complications such as leg ulcers, gangrene, and amputation. Current imaging methods mainly evaluate large blood vessels but do not measure microcirculation in the foot. Computed tomography perfusion (CTP) is a new technique that can assess blood flow in small vessels.
The purpose of this study is to see whether combining CTP measurements with standard CT angiography images and patient clinical information can help predict which PAD patients are more likely to have poor outcomes after surgery to restore blood flow (revascularization). Poor outcomes include death or major limb problems such as amputation or need for another procedure.
This is an observational study. Researchers will collect data from about 200 adult PAD patients who are scheduled to undergo revascularization. Participants will receive routine care including CT scans before and after surgery. No experimental drugs or devices are given. Researchers will follow participants for up to 2 years after surgery through medical records and phone calls to track their recovery and any complications.
The results may help doctors identify high-risk patients earlier and improve treatment decisions.

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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Predictive value of CT perfusion for adverse clinical events after revascularization
Assessment of the predictive value of computed tomography perfusion (CTP) parameters combined with CT angiography and clinical data for postoperative adverse outcomes. Adverse clinical events are defined as all-cause mortality, major adverse limb events (including major amputation and target limb reintervention), or non-healing ulcers/gangrene. Data will be collected through medical records and follow-up visits.
Time frame: From baseline (preoperative) assessment through 2 years after revascularization

Start is estimated for Nov 2026; primary completion for Sep 2029, 34 months later.
Of 138 non-industry observational studies under Peripheral Arterial Disease, half reached primary completion within 40 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 116. This study's planned 34 months is below that.
Counting every sponsor, half of 196 studies reached it within 36 months; a quarter within 22 and three quarters within 73.
