Motivating Structured Walking Activity in Intermittent Claudication
Peripheral Arterial DiseaseIntermittent Claudication1 morePeripheral 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.
The VaSecure BTK Study
Peripheral Artery DiseasePeripheral Vascular Disease1 moreTo 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)
Study of DA+LDD in the Treatment of Femoropopliteal Occlusive Disease
Peripheral Artery DiseaseEndovascular TreatmentThis study will evaluate the effectiveness and safety of directional atherectomy plus local drug delivery using balloon catheter system in the treatment of femoropopliteal occlusive disease. Patients of femoropopliteal occlusive disease will randomly receive directional atherectomy plus local drug delivery using balloon catheter system and dilation using drug-coated balloon. Their clinical outcomes (e.g. 12-month late lumen loss rate, 1-year patency rate of target vessel) in 1 year after the treatment will be compared.
Exercise Test and Sequential Training Strategies in PAD
Peripheral Arterial DiseaseDiabetic lower extremity disease, including peripheral vascular disease, peripheral neuropathy, foot ulcers, or leg amputation. Among them, peripheral arterial disease (PAD) is an important expression of systemic atherosclerosis. With the progress of the disease, impaired peripheral blood circulation will lead to many symptoms and signs, such as pain, paresthesia, and numbness. In past studies show that regular exercise with moderate intensity may help to improve metabolism and hemodynamic characteristics of the individual. In addition, many studies have found that despite substantial organic changes in downstream tissue, exercise training can improve walking ability and aerobic capacity in patients with peripheral arterial disease. To enhance exercise capacity in patients with PAD may involve redistribution of blood flow from vascular beds with lower O 2 exchange rates towards exercising ischemic muscles, an increase in nutritive leg muscle blood flow at the expense of regional shunting mechanisms, increased peripheral O 2 use during exercise attributable to more optimal distribution of leg blood flow, and possible increased muscle capillary density and mitochondrial capacity. Therefore, we tried to mimic local (leg) ischemic- reperfusion by systemic exercise, or to practice remote preconditioning effect by interval occlusion of the blood vessel in the upper arm which acquired ischemic preconditioning effect, and to improve local blood flow. Furthermore, the hemagglutination performance in PAD patients may also be used as an important indicator of cardiovascular disease.
Short-term Perfusion Angiography Pilot Study (SPA)
Peripheral Arterial DiseaseThe Short term Perfusion Angiography (SPA) study is designed to collect 2D Perfusion data from Critical Limb Ischemia (CLI) endovascular (interventional) procedures for information on device performance in a real-world setting.
A Clinical Study Using Adipose-derived Stem Cells for Diabetic Foot
Peripheral Vascular DiseaseIschemia1 moreStem 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.

Peripheral Arterial DiseaseInvestigators 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.
Stella Supera Siberia
AtherosclerosisPeripheral Arterial Disease1 moreEndovascular 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
