Filter by:CLARITY I is a pilot study to identify the clinically appropriate endpoint(s) of a larger, statistically powered pivotal trial for treatment of patients with Critical Limb Ischemia (CLI).
to evaluate the the effectiveness of paclitaxel-eluting balloon for below-the-knee angioplasty in terms of restenosis at 12 months
The principal research question is which treatment modality between open surgical, endovascular and conservative therapy is the most effective in terms of limb salvage, survival and reinterventions in patients with critical limb ischemia
To assess the safety and efficacy of the Lutonix Drug Coated Balloon (DCB) for treatment of stenosis or occlusion of native below-the-knee arteries.
This study will assess the safety and efficacy of intra-arterial infusion and intramuscular injection of an autologous, bone marrow-derived stem cell preparation (ASCT01) in patients with critical limb ischemia who have exhausted all medical and surgical therapeutic options. The safety and tolerability will be evaluated by regular monitoring of the general physical condition, vital signs, and the occurrence of AE and SAE, respectively. Furthermore, the standard biochemical and blood variables (red and white blood cell counts, Hb, Ht, platelets, sodium, potassium, chloride, calcium, phosphor, ASAT, ALAT, bilirubin, total protein, albumin, AP, cholesterol (LDL,HDL), triglycerides, urea and creatinine, immunoglobulins, HBA1c, C-peptide) will be checked before the treatment as well as 30 and 90 days after the treatment.
The purpose of this study is to determine the safety and efficacy of G-CSF-mobilized autologous peripheral blood mononuclear cell injection to ischemic limbs of patients with critical limb ischemia.
The objective Study is to evaluate the short- and long-term clinical outcomes of patients receiving the CryoVein cryopreserved saphenous vein allograft (CVA) as their primary open bypass conduit to assess if there is a quantifiable correlation to time of placement as a primary bypass graft and improved long-term clinical outcomes of patients with critical limb ischemia (CLI).
Severe atherosclerosis in the leg arteries is termed critical limb ischemia (CLI). This condition gives great suffering for the patients in terms of pain, wounds and often developing gangrene. Untreated, the condition has a high risk of amputation. In Sweden, the majority of the patients are investigated and evaluated for treatment. Treatment is carried out either by traditional open bypass surgery or balloon dilatation technology (endovascular treatment). The latter method is still under development, and studies have shown that the treatment has less local and systemic complications than bypass surgery. It is also shown that the method has a limitation in that the treatment effect is less durable. What is the role of minimally invasive technologies should have in the future is unclear, mainly due to its efficiency and cost-effectiveness compared with bypass surgery are not evaluated. In a prospective observational study we intend study the effectiveness, cost-effectiveness and impact on quality of life in patients undergoing treatment for critical CLI with bypass surgery or endovascular treatment in Västra Götaland Region (VGR). All patients over a period of two years, which undergo treatment for CLI with either of the two methods will be included in the study. Patients will be followed up with regard to the clinical efficacy and health-related quality of life after treatment at, respectively one, 12 and 24 and 60 months. Cumulative care costs are calculated and estimates of cost are made. This study aims to increase knowledge about the role of endovascular treatment of CLI shall have in the future.
PAD is caused by an increased flow resistance in atherosclerotic ischemic limbs. The investigators hypothesize that reducing blood viscosity (through controlled phlebotomy), thereby increasing the deformability of red blood cells, should reduce the flow resistance and improve tissue perfusion leading to improved clinical function and a reduction in symptoms. Preliminary data demonstrates that phlebotomy causes a measurable change in blood viscosity as measured by the home-made rheologic method. To evaluate the effectiveness of changes in blood viscosity, obtained through controlled phlebotomy, as a therapy to improve functional status associated with atherosclerotic ischemic limbs in pre-amputation patients.
Clinical trial phase I / II, prospective, multicenter, open, randomized, parallel-groups controlled by two levels of dose to assess the safety and feasibility of the infusion of mesenchymal stem cells from adipose tissue administered intra-arterially in nondiabetic patients with chronic ischemia of lower limbs (CLI) and no possibility of revascularization.
