Active clinical trials for "Peripheral Vascular Diseases"

To define any changes in whole body oxygen consumption that occur following major vascular surgery (open aortic aneurysm surgery; endovascular aortic aneurysm repair; and infra-inguinal lower limb revascularisation procedures).

The specific aim of this study is to prospectively compare outcomes (functional, quality of life, risk-adjusted clinical event) of medical management, surgical or endovascular (angioplasty or stent placement) interventions for the treatment of claudication caused by peripheral arterial disease. This study will test two major hypotheses; Hypothesis 1: At 12-months, surgical interventions are associated with greater improvements in function, claudication symptoms, and health-related quality of life (HRQoL) than endovascular procedures or medical management. Hypothesis 2: At 12-months, surgical and endovascular interventions are associated with greater improvements in function, claudication symptoms, and HRQoL than medical management.

Comparison of two non-invasive methods for measuring tissue oxygenation. One is Transcutaneous Oxygen Pressure (TCPO2) and the other is the new method of Near Infrared Spectroscopy (NIRS) - near infrared spectroscopy in patients with critical limb ischemia (CLI) undergoing invasive treatment (surgical or endovascular).

Non interventional study aimed to establish the prevalence of lower extremity peripheral arterial disease (PAD), defined as an ankle-brachial index (ABI) not above 0.90 in subjects with a moderate risk of cardiovascular disease, with no overt cardiovascular diseases nor diabetes mellitus.

A cholesterol/lipid profile screening project of high risk patients with hyperlipidaemia (secondary prevention) who already receive cholesterol-lowering therapy. Lipid profile and rate of patients who are treated to target (which is <100mg/dl for patients with high risk and <70mg/dl for patients at very high risk) are screened (office-based specialists). The doctors therapy decisions after the screening and possible reasons for these decisions will be documented. Our aim is to evaluate dosing habits, to evaluate how many patients are treated to their LDL-C target and to underline the importance of treating patients to their cholesterol targets.

The purpose of this study is to validate the screening potential of NT-proBNP for the identification of patients scheduled for vascular surgery who would benefit from additional pre-operative cardiac testing. All patients will have NT-proBNP concentrations measured pre-operatively. For low-intermediate risk patients only those with abnormal values will receive further cardiac testing; all high risk patients will be referred for additional testing.

Atherosclerosis, a condition in which fatty deposits build up along the inner walls of arteries, can occur throughout the body. The purpose of this study is to examine the possible genetic differences that may influence where atherosclerosis occurs.

To conduct several studies on the epidemiology of venous disease.

The aim of the proposed study is to define an independent parameter for the diagnostic assessment of the perfusion situation of the calf muscle based on Multispectral Optoacoustic Tomography (MSOT) in a cross-sectional collective of healthy volunteers and patients with PAD. The gold standard is a previously performed angiography of the pelvic and femoral vessels based on routine diagnostics, this Imaging is not mandatory for healthy Control group (study group 1). An independent validation group (study group 2) will validate the results found in study group 1.

This study will focus on determining; How accurate the test is in detecting poor circulation How it's accuracy compares to other commonly used tests, and Whether test results are linked to the chance of ulcer healing or amputation. Across 2 hospitals, 305 diabetic patients will be scanned using the focused ultrasound test as well as other commonly used tests to detect poor circulation. Their results will be compared to a full version of the ultrasound test to identify the most accurate.
