Filter by:The intent of this protocol is to obtain blood samples from subjects with or without a wound, so the blood can be used in wound-related scientific studies. It is also the intent of this protocol to salvage debrided wound material that is normally destined for destruction, so it can be used in wound-related scientific studies.
Varicose veins are a common problem, affecting up to a third of the western adult population. Most suffer with aching, discomfort, pruritis, and muscle cramps, whilst complications include oedema, eczema, lipodermatosclerosis, ulceration, phlebitis, and bleeding. This is known to have a significant negative effect on patient's quality of life (QoL). Surgery has been used for many years, but it is known that there is a temporary decline in QoL post-op. This was demonstrated in our pilot study. Surgery leads to painful and prolonged recovery in some patients and has the risks of infection, haematoma and nerve injury. Recurrence rates are known to be significant. Duplex of veins post surgery has demonstrated persistent reflux in 9-29% of cases at 1 year, 13-40% at 2 years, 40% at 5 years and 60% at 34 years. 26% of NHS patients were 'very dissatisfied' with their varicose vein surgery. Newer, less invasive treatments are being developed. It would be advantageous to find a treatment that avoided the morbidity of surgery, one that could be performed as a day-case procedure under a local anaesthetic, a treatment that could offer lower recurrence rates and allow an early return to work. These should be the aims of any new treatment for varicose veins. Endovenous Laser Treatment (EVLT) is performed under a local anaesthetic and uses laser energy delivered into the vein to obliterate it. The vein therefore need not be tied off surgically and stripped out. The aim of this study is to compare the clinical, cost effectiveness and safety of Surgery and EVLT.
To evaluate the safety of the Compression Device to subjects with venous insufficiency and oedema.
The study will test a new wound healing dressing called Taliderm® on leg ulcers caused by chronic venous insufficiency (CVI). Some people with CVI have poor vein circulation that causes ulcers to develop on the lower legs. This new dressing is hoped to help the ulcers heal more quickly. The study hypothesis is to determine whether the TalidermR Wound Dressing, a poly-N-acetyl glucosamine (pGlcNAc) derived membrane material expedites wound healing in humans with venous stasis ulcers.
The purpose of this study is to determine different risk factors of thromboembolic disease. Different points will be studied 1. do different types of thromboembolic disease (distal Deep Vein Thrombosis (DVT), proximal DVT, Pulmonary Embolism (PE) and DVT, PE without DVT) have the same clinical significance (risk factors and prognosis) ? 2. Is it necessary to obtain a detailed history of thromboembolic disease ? 3. Do older patients have particular risk factors ? 4. Do preventive treatments modify the level of risk factors and the clinical signs of thromboembolic disease ? 5. Do predictive clinical scores have the same performance for both in and outpatients ? 6. Can patients with a potential high level of thromboembolic risk (surgery, pregnancy) but no clinical thromboembolic symptoms, develop a low risk ? 7. The evolution of the disease in patients with negative or positive Venous ThromboEmbolism (VTE) exploratory tests.
Severe skin damage caused by chronic venous disorders (CVDs) results in relentless pain and poor quality of life for millions of adults in the U.S. each year. DVDs are under-recognized and under-treated disorders shat harm the veins of the legs and at worst, cause skin inflammation and venous leg ulcers. A new way to ease the pain and inflammation is proposed in this study of cryotherapy (cool gel wraps) applied to damaged skin of the lower legs of CVD-affected individuals. The study hypothesis predicts that this novel cryotherapy model and method will significantly improve the health and quality of life for those with CVDs and that the intervention will become a standard of care for CVDs. In addition, the method will, over time, reduce health care costs associated with treating poor CVD outcomes.
This trial is designed as a prospective, non randomized, single center clinical trial to determine the safety and efficacy of laser ablation of incompetent perforator veins. Within this clinical evaluation, fifty (50) limbs will be treated with Vari-Lase ®. A duplex ultrasound will verify the presence or absence of incompetent perforator veins (IPV). In addition, the number, diameter and location of the IPVs will be determined. Limbs with IPVs which measure greater than or equal to 3mm in diameter and are located superior to the foot and distal ankle will be considered for entry into the study.
Venous thrombosis is the development of a blood clot in a vein. Post-thrombotic syndrome (PTS) is a painful condition that can develop following a venous thrombosis in one of the deep veins of the leg. While PTS is mainly thought to occur because of damage to the vein, other factors may be responsible for the development of this condition. This study will analyze genetic and biologic samples from participants of a previous study to examine other possible causes of venous diseases and PTS.
To evaluate the efficacy and the tolerance of echoguided sclerotherapy using Lauromacrogol 400 foam for the treatment of Great Saphenous Vein (GSV) insufficiency. A comparative study of 3% versus 1% Lauromacrogol 400 foam.
The primary purpose of this study is to evaluate the safety of DermaStream(tm) in the management of chronic wounds. Other goals of this study are to gain feedback from patients and healthcare providers on the ease of use (the ergonomic aspect) of the device, and to make a preliminary evaluation of the efficacy of DermaStream(tm) in chronic wound management.
