Active clinical trials for "Peripheral Vascular Diseases"

The purpose of this study is to determine whether the intake of Vitamin D has a positive effect on walking ability of patients with peripheral artery occlusive disease. Skeletal muscle fibers change morphology in peripheral artery occlusive disease. In patients with Vitamin D-deficiency there are also changes of skeletal muscle fibers. The investigators have the hypothesis that patients with peripheral artery occlusive disease with subsequent changes of muscle fibers morphology of calf muscles might take profit of the administration of Vitamin D in combination with training.

The purpose of our study is to compare the clinical effectiveness and cost-effectiveness of two treatment strategies of Intermittent Claudication (IC) due to an iliac artery obstruction: to start with SUPERvised Exercise Therapy (SET) and deferred Percutaneous Transluminal Angioplasty (PTA) in case of SET failure, or immediate PTA. It is our hypothesis that PTA as first line treatment is more effective than SET as first line treatment with regard to maximum walking distance, quality of life and costs after one year.

The purpose of this study to compare balloon angioplasty (PTA) vs. cutting balloon angioplasty (CB-PTA) in terms of patency and postintervention inflammation in peripheral artery disease.

To evaluate a new vascular sealant compared to control for the control of suture line bleeding after vascular reconstructive surgery.

This study is designed to assess the effects of socks and bedding materials on foot pain, the level of blood oxygen existing in the feet and quality of sleep in subjects who have chronic foot pain from either diabetic neuropathy or other conditions, e.g., peripheral arterial disease, regenerative joint disease). The three main hypotheses to be tested are: 1)compared to placebo socks, subjects wearing Holofiber socks experience reduction in foot pain, 2)compared to placebo bedding, subjects sleeping in beds lined with a Holofiber mattress pad experience improved quality of sleep and 3) compared to placebo socks, subjects who wear Holofiber socks will have increased blood oxygenation levels in their feet.

Clinical study to investigate the safety and the efficacy of the URECA CTO Device during recanalization and mechanical re-entry into the true lumen after passing the occlusions/calcifications (chronic total occlusions) in the peripheral vasculature.

The SAFE-PAD Study aims to evaluate the long-term safety of paclitaxel-coated devices compared with non-paclitaxel-coated devices for femoropopliteal artery revascularization among a broad, real-world population of patients with peripheral artery disease. This multi-year analysis aims to create an ongoing mechanism to evaluate the safety of paclitaxel-coated devices in real world practice. The null hypothesis is that the paclitaxel-coated devices are associated with an increase in mortality relative to the non-drug-coated devices beyond an acceptable magnitude (i.e. the non-inferiority margin), and the alternative hypothesis is that paclitaxel-coated devices are not associated with an increase in mortality relative to the non-drug-coated devices beyond the non-inferiority margin.

The aim of this explorative pilot study is to present muscle perfusion of the lower extremity in patients with PAD using the Multispectral Optoacoustic Tomography (MSOT) method to build a 3D reconstruction of the calf muscle. This study aims to show the feasibility of 3D reconstruction of this non-invasive method. Advantages in diagnostics for patients with PAD and three-dimensional tomography representation of the perfusion situation based on muscle oxygenation will be evaluated.

Since the length of lesion seems to be negatively associated with stent patency due to restenosis, it is thought that the efficacy of treatment in patients with multiple (> 1) short (focal; > 1 and < 5 cm) SFA lesions can be improved by spot stenting as compared to the use of one long stent. This study proposes to evaluate the endovascular treatment for patients with SFA lesions by comparing two strategies for patients with extensive occlusive SFA disease; 1) short spot (SS) stenting or 2) long lesion (LL) stenting.

This study will assess the benefit of a neuromuscular electrical stimulation device in patients suffering from symptoms and effects of critical limb ischaemia.
