Active clinical trials for "Peripheral Vascular Diseases"

Peripheral arterial disease is part of the diseases derived from arteriosclerosis are the leading cause of mortality in developed countries. There is evidence of the benefits of physical exercise programs supervised in patients with cardiovascular risk. Despite being a treatment with proven efficacy and relatively inexpensive, it continues being little used for the management of patients with intermittent claudication caused by peripheral arterial disease. The objective of this study is to develop an evidence-based intervention strategy on the effectiveness of supervised physical exercise in intermittent claudication to determine its impact compared to standard counselling in these patients.

Peripheral arterial disease affects around 25% of the UK population aged over 55. Left untreated it can lead to debilitating pain, gangrene, amputation and death. It most commonly affects the lower limbs and in the earlier stages of the disease patients can present with a symptom known as intermittent claudication; pain felt in the legs which stops the patient from walking past a certain distance. Current National Institute for Healthcare and Excellence (NICE) guidelines recommend Supervised Exercise as first line treatment for patients with peripheral arterial disease presenting with intermittent claudication. Supervised exercise employs behaviour changing techniques which enable the patient to modify their lifestyles, improving their claudication symptoms, quality of life and reducing their cardiovascular risk. Despite this treatment being significantly more cost-effective than often employed complex endovascular management, most institutions don't offer such programmes citing lack of resources and compliance from clinicians and patients alike. The investigators propose a more cost-effective, resource-savvy solution in the form of REmotely SuPervised ExerCise Training (RESPECT). This allows the patient to exercise in the convenience of their own home, at a time of their choosing but still be supervised via fitness tracker technology and an online fitness platform. This randomised controlled trial will attempt to prove its' effectiveness in increasing claudication distance, improving functional ability, decreasing cardiovascular risk and improving quality of life whilst being more cost-effective than the currently recognised national first line treatment. This trial has the potential to revolutionise the management of patients with peripheral arterial disease.

The purpose of this observational study is to evaluate the performance and safety of endovascular treatment with stenting (Optimed Sinus Superflex 635) or balloon angioplasty (Cardionovum Legflow or Optimed Nylotrack .035 + .018) according to current practice. The goal of the study will be achieved by assessing binary restenosis with duplex ultrasound, peri- and postoperative complications, technical success, target lesion revascularization, amputation and clinical outcome.

Magnesium exerts analgesic effects in several animal pain models and in patients affected by acute postoperative pain and chronic pain of neuropathic origin. There is no evidence that magnesium can modulate pain in patients with peripheral arterial occlusive disease (PAOD). We describe the protocol of a single-center randomized double-blind clinical trial aimed at assessing the efficacy of oral magnesium supplementation in controlling severe pain in patients with advanced PAOD.

The primary objective of the feasibility study is to evaluate the safety and effectiveness of the PQ Bypass Stent Graft System in the treatment of atherosclerotic lesions of the native superficial femoral artery (SFA) or the superficial femoral and proximal popliteal arteries.

The main aim of the present study was to evaluate the therapeutic potential and safety of transarterial infusion of granulocyte colony stimulating factor (G-CSF) mobilized cluster of differentiation (CD) 133(+) cells when combined with percutaneous transluminal angioplasty (PTA) in treatment of below the knee (BTK) peripheral arterial disease (PAD) in diabetic patients.

The primary objective of this trial is to investigate whether intramuscular administration of allogeneic mesenchymal stromal cells (MSC) is safe and potentially effective, assessed as a composite outcome of mortality, limb status, clinical status (Rutherford classification) and pain score (visual analogue scale), in patients with no-option severe limb ischemia (SLI). The investigators will conduct a double-blind, placebo-controlled randomized clinical trial to investigate the effect of allogeneic bone marrow(BM)-derived MSC in patients with SLI, who are not eligible for conventional surgical or endovascular therapies. The investigators intend to include 60 patients, who will be randomized to undergo 30 intramuscular injections with either BM-MSC (30 injection sites with 5*10^6 MSCs each) or placebo in the lower leg of the ischemic extremity. Primary outcome i.e. therapy success, a composite outcome considering mortality, limb status, clinical status (Rutherford classification) and changes in pain score, will be assessed at six months.

This is a 15 patient clinical trial assessing the safety and feasibility of using Endometrial Regenerative Cells (ERC) in patients with critical limb ischemia (CLI) that are not eligible for surgical or catheter-based interventions. Three doses of ERC will be examined. The hypothesis is that ERC administration will be well-tolerated and possibly induce a therapeutic benefit.

The primary objective of this study is to evaluate the safety and performance of the SAMBA Stent and Delivery System in the treatment of femoropopliteal lesions.

To prove the combination of L-citrulline with simvastatin leads to greater improvement in the symptoms of peripheral arterial disease (PAD) than simvastatin alone by evaluating oral L- citrulline or placebo against simvastatin for improvement in treadmill walking distance in patients, 40-75 years of age, who have PAD with intermittent claudication.
