NCT07472049
The goal of this observational study is to characterise the relationships between inflammation, microcalcification and thrombus activity in atherosclerotic plaques in peripheral and systemic vascular territories in patients with symptomatic peripheral arterial disease.
NCT07469020
The goal of this interventional study is to evaluate the rate of existing lower limb peripheral artery disease (PAD) in patients with surgically lumbar spinal stenosis (LSS). PAD and LSS can present similar symptoms and it can be difficult to diagnose PAD using conventional methods, depending on the location of the arterial disease. The main questions it aims to answer are : * What's the prevalence of PAD in LSS patients? * Which exam among routine tools is the most accurate to diagnose PAD in this population? Around their surgery for LSS (a few weeks before or after), participants will be included in a vascular medicine service. After checking of eligibility criteria, they will undergo a contrast-enhanced CT scan for the diagnosis of PAD and various routine diagnostic tests: Doppler ultrasound, treadmill tests, pressure index, pulse palpation.

NCT07433309
Supervised exercise therapy (SET) is the recommended first treatment for patients with leg artery disease (peripheral arterial disease, PAD) causing pain when walking. However, approximately 40% of patients do not benefit meaningfully and go on to require a procedure to open the blocked arteries within three months. This study investigates whether body composition measurements - specifically the quality of muscle and the amount of belly fat - taken from a CT scan already performed as part of routine care, can identify before treatment begins which patients are unlikely to respond to exercise therapy. If confirmed, this approach would allow doctors to use information from a scan patients are already having, with no additional tests, to better match patients to the right treatment from the start.
NCT04089943
MicroRNA-210 (miR-210) can be a potential therapeutic target of patients with peripheral artery disease (PAD). Recent evidence suggests the role of miR-210 and oxidative stress in the pathophysiology of PAD and its association with mitochondrial function, oxidative metabolism, walking distances and quality of life. The protocol evaluates the mechanisms which miR-210 regulates oxidative stress and provides evidence of potential therapeutic strategies.
NCT04238546
The SirPAD trial is an academic, investigator-initiated, single-center, randomized, non-inferiority, open-label clinical trial investigating whether the use of sirolimus-coated balloon catheters in patients with peripheral artery disease of the femoro-popliteal or below-the-knee segment is not inferior to that of uncoated balloon catheters for major clinical outcomes (unplanned major amputation, target limb re-vascularization) and may provide advantages concerning important secondary outcomes, which will be evaluated using a pre-specified hierarchical order as part of the primary analysis.
NCT06068504
The aim of the study will be to evaluate shear stress and blood flow parameters in lower limb arteries during arm cycle ergometer exercise in participants with peripheral artery disease. Twenty patients participants with peripheral artery disease and claudication symptoms will be recruited. Participants will perform 3 experimental sessions in random order. Iarm-cranking (15 sets of two minutes exercise), warm water foot immersion, and control. During the interventions, blood pressure and heart rate will be assessed every 6 minutes. Measurements of arterial diameter, blood flow, anterograde and retrograde shear stress of the femoral artery will be evaluated using a two-dimensional ultrasound device with spectral Doppler.
NCT06321575
The objective of this study is to establish reasonable assurance of safety and effectiveness of the Golazo® Peripheral Atherectomy System when used as indicated in 159 subjects with symptomatic infrainguinal peripheral arterial disease (PAD) in up to 20 investigational sites in the U.S.
NCT05437562
This study follows the Pilot Investigation of Ewing Amputation for Veterans with PAD Undergoing a Below Knee Amputation. The 2 year pilot feasibility phase has concluded recruitment and enrollment. The current phase is a 5 year randomized study of Ewing Below Knee Amputation vs. Standard Below Knee Amputation. If Veterans participate, they will be randomized to either Ewing Amputation or Standard Below Knee Amputation. The scientific premise motivating this proposal is that Ewing Amputation is a promising surgical technique that may improve walking metrics in dysvascular Veterans by providing a better residual limb and improving pain and balance. In preparation of this proposal, we have formed multi-disciplinary surgical teams at each site, and we have been supported by a clinical trial planning meeting to garner the considerable expertise in rehabilitation and amputee assessment from VA and DOD experts to assist in the design of this proposal, testing the overall hypothesis that: Ewing Amputation can help Veterans walk.
NCT07397494
This is a proof-of-concept study with exploratory objective to assess whether superficial tissue oxygenation patterns measured by Snapshot NIRS, in conjunction with the Provocative Elevation Maneuver of the Lower Extremity (PEMLE) and/or the Plantar Palmar Index (PPI), are associated with the severity of peripheral arterial disease (PAD) as determined by standard of care assessments and can be used to assess tissue oxygenation after revascularization, where applicable.
NCT05372952
This feasibility study with a 30 day follow up period will assess the safety and feasibility of the Dynetic-35 stent for the treatment of peripheral iliac artery lesions via a trans-radial approach.
NCT06777901
The goal of this clinical trial is to learn if the Auryon Atherectomy System with balloon angioplasty safe and effective in treating lower limb blockages. The main question it aims to answer is: Is treatment with Auryon Atherectomy System more effective than angioplasty alone in preventing death, amputation, revascularization and improving patency? Researchers will compare the Auryon Atherectomy System with balloon angioplasty to balloon angioplasty alone.
NCT05232474
Intermittent claudication is the most common symptom of peripheral arterial disease (PAD). The recommended therapy is supervised exercise therapy combined with lifestyle counselling, provided by a physiotherapist. Ideally, during the treatment process patients' values and preferences are incorporated with evidence-based knowledge; shared decision making (SDM). Evidence shows the use of SDM in daily practice is scarce. Therefore, personalized outcome forecasts which provide insight into an individual's personal prognosis (called KomPas) were implemented in 2020. Now, as a next step, KomPas is further developed into a guideline-based clinical decision support system. The result is called KomPas+, a tool which integrates the person-centered approach of KomPas with the guideline recommendations for the conservative treatment of people with intermittent claudication.The primary objective of this study is to evaluate the impact of implementing KomPas+ in the physiotherapeutic treatment of patients with intermittent claudication on functional walking distance and health-related quality of life. Secondary, the level of SDM and person-centeredness of physiotherapists using KomPas or KomPas+ will be assessed. Third, the implementation process will be evaluated.
NCT05009862
The purpose of this study is to understand how the drug rivaroxaban improves symptoms associated with peripheral artery disease.

NCT01419080
An estimated 8 million individuals in America are affected by peripheral arterial disease (PAD), blockages of the leg arteries that can cause excruciating calf pain when walking. PAD can have a tremendous impact on patients' quality of life. It is also associated with high rates of heart attacks and premature death. While there are a number of treatments, there have been few previous studies that have prospectively examined treatment patterns for PAD or sought to systematically identify opportunities to improve care. Most importantly, there have been no rigorous studies examining the impact of the disease from patients' perspectives - their symptoms, function and quality of life - as a function of different patient characteristics and treatments. The PORTRAIT study (Phase II) will systematically document the treatments and health status (symptom, function and quality of life) outcomes of 840 US patients over the course of one year (assessments at baseline, 3, 6, and 12 months) from 10 centers to address these gaps in knowledge. It will illuminate whether disparities in treatment or health status outcomes exist as a function of patients' age, gender, race, socioeconomic or psychological characteristics. PORTRAIT will substantially elevate the field and identify critical gaps in the way PAD is currently managed, including potential disparities in care, so that the quality of care can be improved.
