Filter by:The objective of this clinical investigation is to evaluate the safety and efficacy of the Minnow Medical GRST™ Peripheral Catheter System in the treatment of de novo lesions in the superficial femoral artery (SFA) or the popliteal artery.
Background: Muscle atrophy and reduced leg strength are related to exercise intolerance in patients with intermittent claudication (IC), suggesting that strength training (ST) could improve exercise performance in these patients. Objective: Analyze the effects of ST in walking capacity in patients with IC comparing with walking training (WT) effects. Intervention: Patients were randomized into ST and WT. Both groups trained twice a week, for 12 weeks, at the same rate of perceived exertion. ST consisted of 3 sets of 10 repetitions of whole body exercises. WT consisted of 15 two-minute bouts of walking intercalated with 2 minutes of resting. Measurements: Walking capacity, peak VO2, walking economy, ankle brachial index, ischemic window and knee extension strength
The aim of the study is to compare the diagnostic value of this non-invasive vascular imaging tool with the established vascular diagnostic methods for PAD in order to get prognostic data. A higher sensitivity of Fluorescence angiography in order to recognize progression of critical limb ischemia could lead to earlier therapeutic interventions and thereby increase limb salvage. A diagnostic gap would be closed.
The aim of this study is to assess the efficacy and safety of autologous transplantation of bone-marrow cells for therapeutic angiogenesis and vasculogenesis in diabetic patients with non-revascularizable critical limb ischemia.
Primary objective: - To evaluate whether 12 weeks of clopidogrel is superior to ticlopidine in terms of lower risk of the safety events of interests in patients with peripheral arterial disease (PAD) Secondary objectives: - To compare the risk of bleeding adverse events, serious adverse events and overall safety of clopidogrel with ticlopidine - To compare the risk of vascular events of clopidogrel with ticlopidine - To document the long-term safety of clopidogrel for a total of 52 weeks - To document the vascular events of clopidogrel for a total of 52 weeks
The study tests the use of a portable mechanical compression device (FM220, Flowmedic, USA) for the treatment of claudication and peripheral arterial disease. Major endpoints are improved exercise tolerance and relevant blood pressure ratios
To determine the safety and efficacy of the Absolute Pro™ Peripheral Self-Expanding Stent System in subjects with atherosclerotic de novo or restenotic lesions in the native common iliac artery and/or native external iliac artery.
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 better understand why some vein bypass grafts develop narrowing. Evidence suggests that there is a relationship between inflammatory markers in the blood and the narrowing that occurs in blood vessels. In this study, we will look at inflammatory markers in the blood and how well the vein graft functions.
Despite recent advances in stent technology and its widespread application in the treatment of peripheral vascular disease (PVD), incidences of partial or complete blockage of stent lumen (in-stent restenosis) due to in growth of cells (neo-intimal proliferation) is unacceptably high. In diabetics with long superficial femoral artery (SFA) lesions, in-stent restenosis rates are higher than in non-diabetics. Consequently interventional techniques that curtail in-stent restenosis have to be explored. Cryoplasty is a stent expansion method in which a balloon is expanded using pressurized nitrous oxide gas. As the nitrous oxide expands in the balloon it cools the surroundings to about -10 degrees C. This induces programed death (apoptosis) of the smooth muscle cells in arterial wall. The investigators hypothesize that Cryoplasty, by inducing an apoptotic smooth muscle cell response, when applied to post-dilation of nitinol self-expanding stents in the Superficial Femoral Artery (SFA) of diabetics, would lead to decreased in-stent restenosis due to decreased neointimal proliferation.
