The molecular mechanisms involved in venous endothelial dysfunction are largely unknowns. Autophagy is an intracellular mechanism devoted to the removal of damaged cytoplasmic elements. Previous evidence demonstrated that activation of autophagy exerts beneficial effects in the cardiovascular system, reducing cardiac damage and improving cardiac function in response to stress. However, the association between venous endothelial dysfunction and autophagy remains to be characterized. In this study the investigators will test whether reactivation of autophagy through a natural compound (spermidine) is able to improve vascular function in saphenous veins derived from patients subjected to saphenectomy. The same outcome will be evaluated in saphenous veins isolated from patients with atherosclerotic obstructive disease of the lower limbs subjected revascularization through implantation of venous by-pass.
Chronic venous disease encompasses a broad spectrum of clinical presentations and is considered the most common vascular disease. Its causes are diverse, including primary defects of the wall or valves, chronic venous insufficiency, or lesions secondary to thrombosis, a post-thrombotic venous disease, affecting the superficial or deep venous network or both. The major symptom of venous disease is the enlargement of the lower limbs, which can result in edema. The evaluation of the volume of the lower limbs is very important in the diagnosis and follow-up of the venous pathology. There is a great variability of clinical pictures making it difficult to choose the therapeutic gesture. Endovascular venous interventions and conventional venous surgery are major advances in the treatment of venous disease. The variation of lower limb volume in pre and post procedure is a determining factor; thus orienting clinicians for post interventional therapeutic monitoring. Indeed the management of venous disease is multidisciplinary, it involves the cooperation of several specialists as part of its monitoring and its therapeutic management. Our collaborative group includes the Adult and Child Vascular Investigations Department, the Vascular Clinic, the Cardiovascular and Thoracic Surgery Department, and the Interventional Radiology Department. The evaluation of the variation of the volumes of the lower limbs is a capital data for the various specialists for the care in pre and post procedure. A volumetric 3D scanner system guarantees a reliable measurement ensuring optimal evolution and therapeutic follow-up.
The purpose of this research study is to assess the efficacy of custom-manufactured compression hosiery (also known as compression stockings) compared to similar off-the-rack (OTR) compression stockings.
The primary objective of this study is to compare two treatment strategies for symptomatic venous stasis disease with and without venous ulcer. These treatments are compression therapy alone vs. sclerotherapy of refluxing perforating veins with compression.
The BARD® Venovo™ Venous Stent Study is a non-randomized clinical study intended to collect confirmatory evidence of the safety and effectiveness of the Venous Stent for the treatment of iliofemoral occlusive disease.
Introduction: Lower extremity Chronic Venous Insufficiency is a prevalent disease that adversely affects an individual's Quality of Life. Varicose vein endovenous radiofrequency treatment have a lower risk of iatrogenic injuries and offer faster return to work activities, when compared with open surgical techniques. Endovenous electrocoagulation can selectively and safely cause Great Saphenous Vein (GSV) wall necrosis but its clinical results has never been studied before. Objective: The objective of this study is to compare Great Saphenous Vein electrocoagulation and radio frequency (RF) endovascular varicose vein treatment clinical results and quality of life improvement in a prospective double blind randomized controlled clinical trial. Methods: Consecutive patients with varicose veins and primary GSV reflux will be randomized to Electrocoagulation or Radiofrequency endovenous treatment. The primary outcome measure will be GSV occlusion rate at 3 and 6 months after treatment verified by Duplex Scanning (DS). Secondary outcome measures will be pain visual analogue scale (VAS), bruising, neuropathy and vein thrombosis frequency in the immediate postoperative period (1 week); and Clinical Etiology Anatomy and Pathophysiology (CEAP) classification ,Venous Clinical Severity Scale (VCSS), and Aberdeen Varicose Vein Questionnaire (AVVQ), obtained preoperatively, at 3 and 6 months postoperatively. For statistical analysis, we will use the Student's t test, the Mann-Whitney test and Pearson's correlation, considering positive statistical significance when level of p <0.05.
The etiologies of varicose veins and the progression to more serious forms of chronic venous disease and identification of appropriate diagnostic tests to better aid patient management by identifying individuals who may benefit from more aggressive treatment and/ or prophylactic measures.
Leg vein circulation problems can damage the skin of the lower legs, especially around the ankles, by making it discolored, hard, itchy, red, and swollen. Ulcers often develop. Inflammation is often present in the damaged skin. This study will test whether using a special low compression, cooling, boot-like gel wrap placed around the damaged skin of the lower legs will improve the skin circulation and prevent leg ulcers. The study hypothesis is: A cryotherapy, low-compression cooling gel wrap (CW) plus usual care (UC) (leg elevation, compression stockings) intervention compared to a low compression non-cryotherapy "sham" wrap (NW) plus UC will reduce tissue blood flow (perfusion units) and decrease the incidence of venous leg ulcers (VLUs) during the 9-month study period in individuals with Stage 4 and 5 venous insufficiency.
The trial objectives are to compare efficacy relative to pain, along the route of the vein following echoguided endovenous injection of sclerotherapeutic foam into the Great Saphenous vein, of class III microfibre compression (centred at 25 mm Hg) versus class I (10-15 mm Hg) versus class III cotton compression (20 to 36 mm Hg) over 21 days. The main contrast will be the comparison between the first two groups mentioned. All other contrasts will be secondary. The "Class I compression" versus "The two class III compressions" contrast will also be studied. Efficacy will be measured by totalling the VAS scores for maximum pain experienced since the morning and evaluated by the patient at the end of the day. Consumption of analgesics or the number of days of analgesic treatment necessary for the 3 compression types used will be compared. One of the trial objectives is also to show that regular use of a class III compression product leads to a reduction in complications following sclerosis (by reducing the number of non-serious/serious complications specific to sclerosis: matting, pigmentation, inflammation, development of sclerosis requiring drainage, DVT, pulmonary embolism, etc.). The trial also aims to compare the rate of successful sclerosis between the three devices, success being defined by complete or partial occlusion of the great saphenous vein, leading to the disappearance of reflux at the crural level. The other secondary objectives will be patient evaluation of comfort, ease of putting on and taking off the compression hose and a global appreciation of the procedure for echoguided endovenous injection of sclerotherapeutic foam into the great saphenous vein, followed by wearing compression hose.
