Active clinical trials for "Peripheral Vascular Diseases"

The purpose of this study is to show if a new delivery system with a modified stent is safe in treating occluded iliac arteries in patients with peripheral vascular disease. The modified Complete SE delivery system is hypothesized to assist physicians with more accurate stent placement reducing the likelihood of stent 'jumping' seen with the use of many self-expanding stent systems.

The purpose of the study is to evaluate the intermediate and long-term effectiveness of stand-alone atherectomy treatment of peripheral arterial disease in the legs.

This single center, multiple ascending dose study will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of RO4905417 at different doses in healthy volunteers and patients with peripheral arterial disease. Three groups of 10 healthy volunteers will receive RO4905417 (either 3mg/kg, 7mg/kg or 20mg/kg) or placebo iv every 28 days for a total of 3 infusions. In addition, two groups of 6 PAD patients will receive RO4905417 (either 3mg/kg, 7mg/kg) or placebo and 1 group of 20 PAD patients will receive 20mg/kg RO4905417 or placebo iv every 28 days for a total of three infusions. The study will have an adaptive design with ongoing assessment of safety and tolerability prior to initiation of the next dose. All subjects will receive 3 doses of RO4905417 or matching placebo at 28 day intervals. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

This study is intended to evaluate the long-term effectiveness of treatment of de novo or restenotic lesions of the above-the-knee femoropopliteal artery using the Zilver® Flex™ Vascular Stent which has received the CE mark for commercial use. The study is designed as a single arm non-randomized post-approval study.

The purpose of this trial is to demonstrate that the bleeding time of suture holes after construction of arterial bypass anastomosis is shorter after treatment with Lyostypt® than with Surgicel®

The purpose of this study is to investigate the efficacy and safety of autologous transplantation of mononuclear cells with and without G-CSF in patients with chronic lower limb ischemia.

Lower extremity peripheral arterial disease (PAD) is a disease in which fatty build-up, or plaque, accumulates in the arteries of the legs. People with lower extremity PAD often experience leg pain while walking, which is caused by reduced blood flow to the legs. Regular walking has significant benefits for people with blood flow problems in their legs, but previous studies have shown that most men and women with PAD do not walk for exercise on a regular basis. A group home-based walking program may help people with PAD to walk more often and improve their lower extremity functioning. This study will evaluate the effectiveness of a home-based group mediated cognitive behavioral (GMCB) exercise program in helping people with lower extremity PAD to increase their walking frequency and improve their lower leg functioning.

Peripheral arterial disease (PAD) is the most common manifestation of systemic atherosclerosis and accounts for significant morbidity and mortality among end-stage renal disease (ESRD) patients. However, few studies have identified the prevalence and clinical impact of PAD in this specific population. Objectives: To perform a single-blinded parallel, controlled trial to examine the effect of cilostazol treatment on plasma VEGF levels, tissue factors , inflammatory markers (such as IL-6, hsCRP) levels, oxidative stress markers in ESRD patients with PAD Material and methods Fourty HD patients on maintenance HD for > 3months were enrolled in this prospective, single-blinded, randomized study. These patients were randomly allocated into 2 arms. After baseline assessment, patients in the treatment arm received 12 weeks of added on therapy with cilostazol 100mg/day. Blood pressure, heart rate, oxidative stress (malonyldialdehyde, protein carbonyl and ADMA), inflammatory markers (hsCRP, IL-6) and plasma, VEGF and tissue factors levels were measured before and after treatment.

The purpose of this study is to compare a health-counselor mediated telephone counseling intervention to usual care to reduce low density lipoprotein cholesterol (LDL-C) levels in patients with peripheral arterial disease (PAD).

Background: Percutaneous transluminal angioplasty (PTA) has been popularized as a simple, effective and cheap treatment achieving 50-70% symptomatic patency rates in patients with peripheral occlusive disease.. However, the fact remains that the indication for performing PTA are still more based on opinions than on scientific data. The purpose of the trial was to randomize patients primarily referred for intermittent claudication into two groups: One group was offered conservative treatment; the other group was offered conservative treatment combined with PTA. Primary outcome: The patient quality of life. Secondary outcome:Pain-free walking distance; pain-score; death; amputation; changes in relevant biomarkers
