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.\n\nThe 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.\n\nThis 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.\n\nThe results may help doctors identify high-risk patients earlier and improve treatment decisions.",[37,38,39,40,41],"Peripheral Artery Disease (PAD)","CT Perfusion","Revascularization","Microcirculation","Prognosis","NOT_YET_RECRUITING","2026-09-08",{"date":45,"type":46},"2026-09-14","ACTUAL",{"date":48,"type":33},"2026-11-01",{"date":50,"type":33},"2029-11-30",{"name":5,"class":6}]
