Filter by:The objective of this clinical investigation is to evaluate the clinical outcome (up to 12 months) of treatment by means of stenting with the RoadSaver (Terumo) in subjects at high risk for carotid endarterectomy requiring carotid revascularization due to significant extra-cranial carotid artery stenosis.
This is a prospective, multi-center, single-arm, non-blinded study designed to investigate the safety and efficacy of the Tack Endovascular System in subjects with post-balloon angioplasty (post-PTA) dissection(s) type(s) A through F in the superficial femoral and proximal popliteal arteries ranging in diameter from 2.5mm to 6.0mm.
Some studies have reported improved vascular function with the supplementation of L-arginine in participants with cardiovascular disease (CVD). Several clinical studies have also begun the investigation of L-arginine supplementation in participants with peripheral artery disease (PAD). This is particularly important as currently there are limited options available to medically manage intermittent leg pain resulted from PAD. Although some of these short-term clinical trials suggested that oral L-arginine improved walking distance or improved walking speed in participants with PAD, these results were not consistent. Further, only 1% of the oral supplemented L-arginine is available for the NO production as the rest is metabolised by the body. A better way to provide the body with substrate to produce NO is therefore needed. The natural amino acid and food component, L-citrulline has been suggested to be a good candidate for this purpose. L-citrulline, named after watermelon citrullus vulgaris from which it was first isolated, is a natural precursor of L-arginine. Studies have shown that L-citrulline is metabolised by the body to a lesser degree compared to L-arginine and hence is an effective precursor of arginine in peripheral tissues, including endothelial cells. Oral L-citrulline supplementation also eliminates some of the unwanted effects associated with oral arginine supplementation and it is well tolerated without known side effects. In addition, L-citrulline is a supplement that is available over-the-counter. Thus, oral supplementation of L-citrulline may be a new intervention strategy in participants with PAD. The investigators hypothesize that the oral food supplement L-citrulline, unlike L-arginine, reverses endothelial dysfunction. In a multinational, multicenter, double blinded, randomised, placebo-controlled cross-over trial the effects of L-citrulline in peripheral artery disease will be investigated.
The endovascular therapy prevailed in nearly all regions of peripheral artery disease over open surgery techniques. However, in treatment of the common femoral artery vascular surgery is still the gold standard of therapy. One-year patency rates are between 90% and 95%. Today, only in selected cases an endovascular procedure for common femoral artery diseases is recommended. The primary objective of this study is to compare the performance of directional atherectomy and drug-coated balloon angioplasty over vascular surgery in common femoral artery lesions in a prospective, multi-center, randomized clinical trial.
The literature has shown that supervised exercise programs for patients with PAD and who report intermittent claudication (IC) have improved health outcomes, but this is not locally available. Introducing the use of a pedometer may act as a method to encourage patients to continue on their independent exercise regimen. There is very little literature which has examined the effectiveness using pedometers as a measure of compliance within this population.
Some people experience a cramp-like leg pain during walking that is relieved only by rest. This is called intermittent claudication (IC) and it is a common symptom of peripheral arterial disease. Patients with IC struggle to walk, which in turn lowers their quality of life. The intensity of IC pain experienced during walking depends on several factors, including the type of footwear worn. For example, non-supportive shoes may make the calf muscles work harder during walking, leading to earlier and more-severe symptoms of IC. A member of the research team has developed a shoe that reduces the work done by the lower-leg muscles during walking. Preliminary data indicate that, when wearing these "unloading shoes", people with IC were able to walk further without pain as compared with when wearing a normal pair of shoes. The current project aims to provide further information on the usefulness and acceptability of these shoes. Forty people with IC will complete a set of three walking tests on two separate occasions; once whilst wearing the unloading shoes, and once whilst wearing some normal shoes. The participants will then be given a pair of unloading or normal shoes to wear for two weeks, after which we will collect information on how acceptable the shoes were to wear via a survey of all participants and one-to-one interviews with a subset of participants.
The purpose of study was to test whether rivaroxaban added to standard of care treatment, when compared to placebo, had the potential to reduce the incidence of the clinical events related to the clots and complications of the heart and brain (CV death, MI, or stroke) or the legs (acute limb ischemia or major amputation) in patients who had undergone recent procedure(s) to improve the blood flow of their legs.
Define responses to exercise on both arterial bruits and oxymetry in patients referred for suspected endofibrosis.
The GoldenFlow (Lifetech Scientific, Shenzhen, China) is a novel woven-nitinol stent designed to have superior radial strength, flexibility and durability compared to standard nitinol stents for femoropopliteal lesions. This is a first-in-man study to evaluate the safety and efficacy of GoldenFlow woven-nitinol stent for intraluminal treatment of peripheral vascular disease in the femoropopliteal arteries.
A growing body of literature indicates that up to 80% of amputees may have phantom limb pain (PLP). The first cause for limb loss is vascular disease. Usually, amputees who suffer from PLP are suboptimal treated. Therefore, many amputees are disabled by their chronic pain. The etiology and pathophysiology of PLP are poorly understood. Some studies suggest a somatosensory cortex reorganization. Transcutaneous Electrical Nerve Stimulation (TENS) is a analgesic technique. TENS apply a low voltage electrical current through the skin using surface electrodes in order to stimulate afferent nerve fibbers. Because of the lack of evidence to support any treatment for PLP, interest has turned to preventing it instead. The aim of this study is to assess if the early use of TENS in the immediately postoperative of major limb amputation due to peripheral vascular disease, should decrease the PLP incidence. TENS should interfere in the mechanism of PLP production to level of the pain fibers conduction.
