Active clinical trials for "Peripheral Arterial Disease"

The registry will enroll patients with claudication or critical limb ischemia and angiographically significant lesion(s) in arteries of the lower extremity. Subjects will be treated with the Lutonix® Drug Coated Balloon Catheter for approved indications according to the current country-specific Instructions for Use (IFU) and followed clinically for 1 year.

This study aims to demonstrate if remote ischaemic preconditioning (RIPC) may confer renal protection in patients undergoing peripheral angioplasty. Patients will be randomised to receive RIPC and biomarkers for renal injury will be analysed post procedure to determine if any protective benefit was obtained.

The Peripheral Arterial Disease prevalence is around 3-10 % of the world population. Exercise plays an important role in treating these patients.

Comparing the efficacy and safety of drug-eluting balloons (DEB) for the treatment of below-the-knee peripheral arterial occlusive disease with conventional balloon angioplasty (BA).

Stem cell therapy has been a new and effective therapy in recent years for diabetic foot.This study intends to establish an optimal clinical research program, and attempts to break the technical bottleneck in the stem cell therapy for treating diabetes related vascular complications.

Background: Lower limb arterial revascularization procedures, either percutaneously or surgically performed, are an established treatment modality of ischemic foot ulcers, especially in the setting of a critical limb ischemia. Many other lower limb ulcers are secondary to a combined disease, which may include a concomitant venous disease (chronic venous insufficiency or varicous disease) or a micro-angiopathic disease (i.e. small vessel disease). In this setting, and especially in the absence of a concomitant severe macro-angiopathic disease, the safety and efficacy of a percutaneous lower limb revascularization have so far never been evaluated in a prospective study. Aim: This study is aimed to evaluate the safety and the efficacy of an endovascular revascularization approach of the lower limb, in all consecutive patients presenting with a non-healing ulcer associated with a mild to moderate peripheral artery disease (i.e. mixed-origin ulcers). Material and methods: This prospective study will consecutively include all patients presenting with a non-healing ulcer. Included patients must have all the concomitant ulcer co-factors being adequately treated for at least 6 months. Accordingly, an underlying venous disease, infectious disease or inflammatory disorder must be previously evaluated and adequately treated (i.e. compression stocking, varices stripping, antibiotics, local ± systemic anti-inflammatory, etc.). Furthermore, a non-invasive arterial evaluation must be obtained in all patients. The arterial screening must included an ankle-brachial index (ABI) and toe pressure (TP) measurements, a trans-cutaneous oxygen measurement (tcPO2) at the foot and calf levels and a non-invasive arterial mapping (i.e. angio-CT or angio-MRI). This arterial work-up must be compatible with the presence of a mild to moderate peripheral artery disease without any sign or criteria suggesting the presence of a critical limb ischemia. End-points: The success rate of perform an endovascular revascularization intervention in all consecutive patients which qualify according to the inclusion criteria (technical feasibility). Establish the proportion of procedural related complications (safety). Analyze the clinical and the para-clinical improvements in term of heal of the ulcers, as well as the improvement of the ABI, TP, tcPO2 at 1 week, 1-3-6 months after the procedure (efficacy). Sample size: The investigators plan to include ≈ 30 patients in two years. After 1 year of enrollment the investigators will perform an interim analysis and will decide at that moment, according to the observed end-points, if prolonging the study would be of any scientific value or if the study has to be interrupt earlier because of a significant improvement of all already treated ulcers.

The study will compare Padd, a non-invasive automated optical device which uses a functional test to assess peripheral arterial disease (PAD), and Ankle brachial pressure index (ABPI) in the detection of PAD using as a gold standard, colour duplex ultrasound, in participants drawn from general practice, a hospital diabetic clinic and a tertiary vascular disease referral centre. The study hypothesis is that Padd performs at least as well as ABPI in detecting PAD.

The purpose of this study is to compare the effectiveness of aortic stent surgery versus exercise therapy in individuals with aortoiliac insufficiency.

The purpose of this study is to learn about the impact of text messaging on physical activity in persons with risk factors for peripheral arterial disease (PAD).

Absorbable sutures are not generally accepted by the majority of vascular surgeons for the possible complications such as the breakage of the suture at the anastomoses level. Some experimental and clinical studies in the current literature demonstrated that the use of absorbable sutures may even reduce some important complications such as restenosis. The aim of this study is to compare absorbable and non-absorbable sutures in patients undergoing peripheral vascular surgery with vein bypass grafting.
