Active clinical trials for "Peripheral Arterial Disease"

In this investigation, the investigators will attempt to demonstrate that patients who have received nerve blocks (regional anesthesia) prior to open surgical vascular bypass of the lower extremities (infrainguinal bypass grafting) will have improved surgical outcomes namely a reduction in the rates of death, wound infection, graft thrombosis, graft revision, and amputation. As well, the investigators anticipate that patients who have undergone regional anesthesia for infrainguinal bypass grafting will have improved secondary outcomes with respect to a decreased length of stay, narcotic consumption, nausea and vomiting, post-operative cognitive dysfunction, major cardiac events, post-operative pain, and hyperglycemic episodes.

The purpose of this study is to determine if the addition of a catheter-based local delivery of paclitaxel into the peripheral arterial vessels in patients with peripheral arterial disease (PAD) and subsequent restenosis of the femoropopliteal region would benefit from this type of investigational intervention with a known antiproliferative agent.

The purpose of this study is to demonstrate improvement in flow mediated dilation (FMD), a functional endpoint associated with the progression of atherosclerosis, when switching from cigarettes to the Tobacco Heating System (THS) in subjects with peripheral arterial disease (PAD) and/or coronary artery disease (CAD). The study is planned to be conducted in the US, Europe, and Asia.

The objective of this registry is to collect observational data under local standard of care and evaluate safety and performance of the Serranator® Alto in treatment of peripheral artery disease (PAD), or dysfunctional native or synthetic arteriovenous dialysis fistulae in a real-world scenario.

Although microparticles have been well-documented as mediators of inflammation and coagulation in various cardio-vascular disease events, it is currently not known how Percutaneous Transluminal Angioplasty (PTA) for peripheral arterial disease influences microparticle numbers, phenotype and distribution pre- and post interventionally and how they are related to or affect the incidence of early re-stenosis - or if indeed they may be used to predict patients at risk of early re-stenosis.

Background: The plant-derived omega-3 fatty acid alpha-linolenic acid (ALA, 18:3-n-3) may reduce the risk of atherosclerotic cardiovascular disease, including incident myocardial infarction, ischemic stroke and peripheral artery disease. However, the results of previous studies have been inconsistent. Objectives: To investigate the associations between dietary intake of ALA, adipose tissue content of ALA, and the risk of the major atherosclerotic cardiovascular diseases incident myocardial infarction, ischemic stroke and subtypes, and peripheral artery disease. Methods: This project will be based on data from the Danish cohort study Diet, Cancer and Health which consisted of 57,053 men and women at recruitment between 1993 and 1997. Dietary intake of ALA will be assessed using a validated semiquantitative food-frequency questionnaire and adipose tissue content will be determined with the use of gas chromatography analyses of adipose tissue biopsies collected at baseline. Also, detailed information on lifestyle factors, medical history and anthropometri was collected at baseline. Incident cases have been identified through national registries and the diagnoses have previously been validated. Analyses of dietary intake of ALA will be analysed using a traditional cohort design, whereas analyses on adipose tissue content of ALA will be analysed based on a case-cohort design. Hazard ratioes with 95% confidence intervals will be used to describe the associations between the exposure variables and the outcome variables of interest.

A retrospective study to evaluate Turbo Power laser atherectomy + drug coated balloon (DCB) angioplasty for the treatment of femoropopliteal de novo/restenotic lesions and in-stent restenosis (ISR).

Primary objective: To document change in translesional pressure gradients (TLPGs) and ratios (fractional flow reserve) using the NAVVUS RXi catheter following endovascular treatment for symptomatic lower extremity peripheral arterial disease. Secondary objectives: Evaluation of correlation of the ABI and TBI and TLPGs at baseline and following endovascular therapy Evaluation of the correlation between the change in WIQ, TCOMs, wound size and change in TLPGS Evaluation of correlation between lesion severity by QVA (MLD, % diameter stenosis) and TLPGs Evaluation of baseline MLA, MLD, plaque burden by intravascular ultrasound (optional) and TLPGs

Investigators conduct a monocentric pilot study with the objective to determine the hemodynamic parameter of fluorescence angiography (slope, amplitude, saturation time ) best correlated with toe pressure in patients with suspicion of critical limb ischemia.

The measurement of limb skeletal muscle perfusion and perfusion reserve during exercise is an approach that can assess the total impact of the complex pathophysiologic processes in patients with limb ischemia, particularly in those with diabetes in whom distal arterial disease and abnormal microvascular functional responses are common. This trial is designed to: (a) optimize methods for assessment of limb perfusion at rest and during stress using contrast-enhanced ultrasound (normal subjects) and a microbubble contrast agent that is able to provide non-linear signal without destruction at medium acoustic pressures, and (b) to test whether perfusion imaging provides incremental information on the severity of disease in patients with peripheral artery disease.
