Active clinical trials for "Peripheral Vascular Diseases"

The Jetstream System is a commercially available rotating, aspirating, expandable catheter designed to remove atherosclerotic plaque and blood clots in the lower limbs. The purpose of this study is to use intravascular ultrasound (IVUS) during the interventional procedure to measure the amount of plaque and blood clots removed by the Jetstream System.

The Destiny trial compares the use of bare metal stent systems with drug eluting stent systems in the treatment of infrapopliteal lesions in patients with Critical Limb Ischemia. It will be investigated whether there is a difference in 12 month angiographic patency of the stented area using the 2 different stent systems.

Hypothesis #1. Supervised exercise rehabilitation will result in greater increases in exercise performance, peripheral vascular function, and health-related quality of life than compared to the attention-control group. Hypothesis #2. The change in peripheral vascular function will be predictive of improved exercise performance following the supervised exercise program.

The objective of this clinical investigation is to evaluate puncture site complication rate as well as the short- and long-term (up to 24 months) outcome of treatment by means of Astron Pulsar / Astron Pulsar-18 stent implantation in symptomatic (Rutherford 2-4) femoro-popliteal arterial stenotic or occlusive lesions, using 4F compatible devices of BIOTRONIK and without the use of a closure device. The hypothesis is that the primary patency at 12 months is non-inferior to the primary patency obtained in the Durability study (72.2%).

Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

A randomised controlled trial evaluating the feasibility and acceptability of a 12 week lower body blood flow restricted resistance exercise programme for people with peripheral arterial disease.

Forty patients of both sexes, aged between 50 and 60 years, were chosen from an outpatient vascular clinic in the El Sahel Education Hospital. Patients have been examined and referred to by a vascular specialist.

The objective of this study is to evaluate the benefits of participating for 8 weeks in a home-based daily treatment with heat therapy (HT) or a thermoneutral control intervention, as assessed by vascular function, walking tolerance and quality of life.

Investigators hypothesize that high-dose n-3 polyunsaturated fatty acids (PUFA) oral supplementation will improve systemic inflammation, vascular function, and symptomatic status of patients with PAD. Investigators will explore novel mechanistic pathways by which n-3 PUFA affect PAD, evaluating the role of specialized lipid mediators involved in the resolution of inflammation.

Several studies have shown that stenting of the femoropopliteal artery in the lower leg leads to improved overall results compared to balloon angioplasty alone. However, scar tissue development can occur within the stent, a process called restenosis. Treatment of these in-stent restenotic lesions has a high procedural success rate but recurrence of scar tissue is frequently seen. Several methods have been proposed to treat in-stent restenosis in the lower leg arteries but mixed results have been noted. In this study we hypothesize that simultaneous tissue excision and aspiration using the JetStream Navitus device (Medrad) can lead to a high rate of acute procedural success with low intraprocedural complications and an acceptable recurrence rate of restenosis at 6-month follow-up.
