Active clinical trials for "Arterial Occlusive Diseases"

The objective of this study is to test the hypothesis that AMG0001 treatment is safe and induces angiogenesis as detected by improved wound healing, reduction in amputation, improved pain at rest and hemodynamic measurement and to assess the effectiveness of the administrative method.

This study will look at the performance of the Cordis S.M.A.R.T.™ CONTROL ™ Nitinol Stent System for the treatment of TASC C & D superficial femoral artery long lesions (up to 22 cm) in comparison with the Bard® Luminexx™ 6F Vascular Stent as determined by the primary patency rate at 6 and 12 months post procedure.

The primary purpose of this study was to assess the overall safety of different dose regimens of AMG0001 (HGF transferred via plasmid vector) as well as evaluate the improvement of blood perfusion in subjects with critical limb ischemia (CLI). This study also evaluated the improvement in wound healing without adverse effects on the quality of life, as well as the potential reduction of amputation, mortality and rest pain in the CLI population.

This trial is for patients with acute occlusion of one of the arteries supplying blood to the leg. The trial is designed to determine the safety and activity of a novel clot dissolving (thrombolytic) drug (alfimeprase).

To determine whether combined therapy with the lipid lowering agents colestipol hydrochloride plus niacin would produce significant change in coronary, carotid, and femoral artery atherosclerosis and coronary bypass graft lesions as determined by angiography. Also, to determine possible correlations between lesion changes and plasma lipid and lipoprotein cholesterol levels and to explore interrelationships of atherosclerosis change in femoral, coronary, and carotid arteries.

Pneumatic tourniquets are widely used not only to reduce blood loss and to ensure optimal operating conditions during extremity surgery, but also in regional anesthesia (local intravenous) vein puncture and to control life or limb threatening conditions. However, compression of the tissues under a tourniquet is associated with soft tissue damage involving the skin, vessels, muscles, and most importantly, nerves, and are commonly pressure related and can be affected by tourniquet time as well. Therefore, the "minimal tourniquet inflation pressure" necessary to provide a bloodless field has been suggested to minimize the risk of complications from excessive inflation pressure. Arterial occlusion pressure (AOP) is the lowest pneumatic tourniquet inflation pressure required to stop the arterial blood flow into the limb, and its usage has been shown to be useful in optimizing tourniquet cuff pressures. The pressure to which a pneumatic tourniquet cuff should be inflated depends on a number of variables, including the patient's age, skin, blood pressure and the shape and size of the extremity in question, as well as the dimensions of the cuff. One of the estimation method for AOP is based on systolic blood pressure (SBP) and tissue padding coefficient (KTP) values (AOP=[SBP+10]/KTP) according to extremity circumferences. Unver B. et al., used this method to estimate effective tourniquet pressure in total knee replacement under hypotensive general anesthesia tourniquet pressure achieved was 169.7±7.9 mmHg, while Tuncali et al., tested it again in different lower limb surgeries under general or neuraxial anesthesia with normotensive techniques and the achieved maximal tourniquet pressures used was 173.3±15.6 mmHg. Hong-yun Liu et al., established a new occlusion pressure mathematical model for the upper limb based on the correlation analysis between several possible influencing parameters and the minimal pneumatic tourniquet pressure.

The purpose of this study is to assess the efficiency of outpatient surgery compared to conventional hospitalization in endovascular treatment of occlusive arterial disease. A cost-utility analysis will be conducted from a societal perspective. Patients referred for peripheral arterial disease (PAD) will be randomized in two arms and a 3 months follow-up will be performed.

The objective of this patient registry is to assess the clinical use of the Lutonix 035 DCB PTA Catheter in a heterogeneous patient population in a real world and on-label clinical application.

Coronary artery bypass grafting (CABG) using the radial artery (RA) has since the nineties gone through a revival. The initially reported worse outcome in RA graft patients compared to patients grafted with the saphenous vein (SV) has since been corrected. Studies have shown better patency when using RA, so the RA is going to be preferred more and more especially in younger patients where long time patency is critical. During the last 10 years endoscopic techniques to harvest the RA have evolved. Multiple different techniques have been used, but now the equipment and technique have been refined and are highly reliable. The investigators hypothesize that the endoscopic technique has less complications and a just as good patency as open harvest. There are also two possible ways to use the RA as a graft. One way is sewing it onto the aorta and another way is sewing it onto the mammarian artery. The investigators hypothesize that using it on the mammarian artery is superior as a revascularisation technique with just as good a patency as sewing it directly onto the aorta.
