Filter by:The purpose of this clinical trial is to analyze patency after autologous infrainguinal bypass surgery in patients receiving a venous conduit versus a covered venous conduit.
Post-thrombotic syndrome (PTS) is the most frequently observed chronic complication of deep vein thrombosis (DVT), with an estimated cumulative incidence of 20-50%. Endovascular venous recanalization with angioplasty and stenting of obstructive lesions is the recommended treatment option to reduce or correct the symptoms of DVT. However, its impact on the physical capacity and breathlessness of patients has not been fully demonstrated. The heterogeneous evidences of clinical improvement is probably related to the presence or absence of collateral veins developed in these patients with proximal venous obstruction (iliac or iliofemoral with or without inferior vena cava involvement), which ensure the cardiac venous return. The aim of this study is to compare changes in maximal oxygen uptake after endovascular venous recanalization in DVT patients and to evaluate the hemodynamic, respiratory and muscular improvement induced by the restoration of venous flow in the occluded segments.
The aim of this study is to demonstrate the safety and effectiveness of the Lobster interspinous spacer device for the treatment of Lumbar Spinal Stenosis in comparison to an SSED-based performance goal.
Supervised exercise for intermittent claudication is a first line therapy for peripheral arterial disease, as recommended by the National Institute for Health and Clinical Excellence and the European Society for Vascular Surgery. However 2/3 of British trusts cannot implement this due to gym availability, costs, travel time and the requirement for social distancing. During the COVID-19 lockdown the investigators successfully performed a feasibility study for remotely supervised exercise using an electronic walking log and fortnightly video calls with a physiotherapist. RESET2 aims to compare the benefits of and adherence to remotely supervised exercise with self-directed exercise to absolute walking distance.
This study will focus on people with claudication from peripheral arterial disease. The investigators are researching whether a multicomponent therapeutic can increase the production of Nitric Oxide in the blood and whether that leads to an improvement in pain free walking distance and overall physical activity.
Dual antiplatelet therapy has a key role in a prevention of thrombosis of treated artery in patients undergoing percutaneous transluminal angioplasty (PTA). Weak therapeutic response and presence of residual platelet activity is related to high risk for stent thrombosis and it is well in known in coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). However there are few data on the association between a different entity of platelet inhibition on antiplatelet treatment and clinical outcomes in patients with peripheral artery disease (PAD). The aim of this study was to evaluate the degree of on-treatment platelet reactivity, and its association with ischemic and hemorrhagic adverse events at follow up in PAD patients undergoing PTA.
Interventional strategies aim to restore tissue perfusion. However, despite the simple reopening of a narrowed artery they affect endothelial function, perpetuating dysfunctional vascular homeostasis. PTA and atherectomy might alter the endothelial function but the mechanisms are incompletely understood. The primary goal of atherectomy is vessel preparation and improving compliance, which could aid in preserving vessel functions. Aim of this study is to determine safety, efficacy, patency and vessel functions in the femoropopliteal artery following atherectomy and DCB.
Endovascular treatment of the superficial femoral artery has a high initial success rate, but restenosis occurs in up to 60% of cases. While restoration of tissue perfusion is achieved, interventional strategies affect endothelial function. Endothelial dysfunction is the pathophysiologic principle involved in the initiation and progression of arteriosclerosis. The aim of this study is to determine the impact of endovascular strategies in the superficial femoral artery on local and systemic endothelial and vascular function.
This study evaluates the effect of additional hyperbaric oxygen therapy after lower extremity amputation. The patients will be randomized after amputation to either a treatment group receiving hyperbaric oxygen therapy, or control group.
Subjects with a known diagnosis of peripheral artery disease as measured by an abnormal ankle brachial index (<.9 or >1.1) will undergo a single 5 min exposure of 670 nm light, 1 cm above the gastrocnemius muscle. Blood flow will be measured by infusion of ultrasound contrast and subsequent acquisition of ultrasound images. 2 blood samples will be collected for measurement of nitric oxide metabolites.
