Active clinical trials for "Peripheral Vascular Diseases"

Peripheral arterial disease can cause leg pain or discomfort (called intermittent claudication (IC)), which limits the ability to walk and carry out everyday activities. Lifestyle changes, like increasing walking, can lead to improvements, but can be a challenge to begin and then continue. The aim of this study is to investigate if a physiotherapist-led, behaviour change treatment effects walking in people with IC. The treatment is designed to build an understanding of IC and walking exercise and help individuals develop strategies to increase regular walking. The trial will recruit 192 adults (aged 50 years and over) with IC. All participants will visit King's College London or their local hospital to complete two short walking tests and answer questionnaires about their daily activities, beliefs about their symptoms and treatment, quality of life and the costs of having IC. Participants will then be randomly assigned to receive either the new treatment or continue with their usual NHS care. The new treatment involves two 60-minute face-to-face sessions (at the participant's home or local hospital) and two 20-minute telephone calls with a physiotherapist who will discuss participants' understanding and beliefs about IC, walking and help participants to set goals and plans to increase walking over 12 weeks. Participants will be provided with a step counter (pedometer) and walking record. After 12 weeks, all participants will attend a second appointment where they will repeat the walking tests and fill out another set of questionnaires. A final set of questionnaires will be completed by all participants after 6 months (by post or electronically). Some participants will be invited to provide feedback on their experience of the treatment and trial by telephone or a face-to-face interview with a researcher.

After endovascular treatment (EVT) for peripheral artery disease (PAD), dual antiplatelet therapy (DAAT) of aspirin (ASA) and clopidogrel are currently drug of choice to prevent occlusion. Anplone SR®, controlled-released Sarpogrelate hydrochloride, has been introduced as an anti-platelet agent for the drug of PAD. The aim of this study was to compare the efficacy and safety of Anplone + aspirin and clopidogrel + aspirin in patients who underwent EVT for femoro-popliteal occlusive disease.

To assess the safety and performance of the VaSecure drug-coated PTA balloon catheter in the treatment of patients with Chronic Limb Threatening Ischemia (CLTI) of the lower limb below the knee (BTK)

Endovascular treatment with stenting is currently used in the treatment of femoro-popliteal lesions. This technique tends to extend to lesions for which the gold standard remains until now the open surgery treatment (lesions TASC C and D). The primary objective of the study was to evaluate the clinical efficacy at 12 months of the SuperA stent (Abbott) in the treatment of long de novo atherosclerotic lesions TASC C and D in patients with symptomatic peripheral arterial disease. The secondary objectives are to evaluate the clinical effectiveness of the SuperA stent at 24 months, according to clinical, morphological and haemodynamic criterias, the possible influence of calcifications and the quality of life of patients

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.

Investigators hypothesize in patients presenting with significant peripheral arterial disease with clinical indications for treatment with angioplasty, there will be a difference in 12 month patency between the subjects with Lutonix 035 Drug coated Balloon PTA Catheter and IN.PACT Admiral Paclitaxel-Coated PTA Balloon Catheter.

The aim of this study is to perform a randomized, controlled trial to compare percutaneous transluminal angioplasty using paclitaxel eluting balloon (PEB) or using a conventional balloon for treatment of superficial femoral artery in-stent restenosis.

The objective of this study is to determine whether rifalazil can significantly increase peak walking time (PWT) in patients with peripheral arterial disease (PAD).

Sympathetic overactivity partly promotes the development of peripheral artery disease which mainly leads to ischemia of the lower limbs. Endovascular arterial denervation (ED) is a minimally invasive technique which could deliver Radiofrequency energy by a multi-electrode catheter to the Lower limb artery to restore Sympathetic activity. The purpose of this study is to evaluate the effects of multi-electrode radiofrequency ablation system on lower limb ischemia with PAD.

Diabetic lower extremity arterial disease ( DLEAD ), is a common complication of type 2 diabetes. However, DLEAD remains less studied than other diabetic vascular complications; and only few randomised controlled trials (RCTs) have dealt with major lower-limb adverse events as prespecified endpoints. Studies have suggested that glucagon-like peptide-1 (GLP-1) analogues have a protective effect on the development of atherosclerosis, potentially mediated via the GLP-1 receptors expressed on endothelial cells, smooth muscle cells, and in monocytes/macrophages. The investigators aim to evaluate the improvement of lower extremity ischemia in patients with type 2 diabetes mellitus complicated with lower limb vascular lesions after liraglutide, compared with the standard-of-care treatment group.
