Filter by:The purpose of this study was to evaluate the efficacy and safety of microwave ablation catheter in the treatment of varicose veins in lower extremities,meanwhile, to compare the quality of subjects'lives before and after treatment.
The prevalence of superficial chronic venous insufficiency (CVI) of the lower limbs is estimated at 18 million French people. The number of patients operated for varicose veins is around 300,000 per year. Post-operative complications such as venous ulcer, venous thrombosis and varicose vein rupture require a lot of medical care. Varicose veins are responsible for a decrease in quality of life and represents 1 to 2% of total health expenditure. Currently, operating techniques tend towards minimally invasive procedures in order to minimize the surgical trauma, improve patient comfort and reduce the time of postoperative work stoppages. This study aims to compare two surgical techniques for the treatment of superficial chronic venous insufficiency of the lower limbs : phlebectomy, the gold-standard technique, and endovenous steam treatment. Several studies have already been carried out on endovenous steam treatment for saphenous veins but none has been published concerning the tributary veins.The main objective of INVOLVE is to assess the quality of life of patients 1 month after surgery. Clinical improvement and economic impact will also be evaluated.
With this prospective controlled trial, we hope to obtain more information about the coexistence between venous insufficiency and nocturia. In our opinion, venous insufficiency (CEAP 2-3a) leads to an increase in fluid accumulation in the lower limbs due to moving around all day. When laying down during nighttime, this fluid is reabsorbed into the systimic fluid pool, leading to an increase in diuresis and thus an increase in nocturnal voiding. Aim of this study is observe difference in nocturnal frequency and urine production before and after surgical treatment of venous insufficiency.
Endothelial dysfunction is assessed in patients with chronic venous insufficiency of lower limbs (grade C4 according to C - clinical manifestations, E - etiologic factors, A - anatomic distribution of disease, and P - underlying pathophysiologic findings (CEAP) classification) prior to and after endovenous surgical procedure, i.e. endovenous laser ablation of great saphenous vein, microphlebectomy of varicose branches. Two treatment groups (with and without additional pharmacotherapy) are compared.
Nocturia, or waking during the night to pass urine, is a multifactorial disease. An important cause of nocturia are peripheral edema due to accumulation of fluid in the lower limbs. Venous insufficiency is an important cause of peripheral edema. The investigators hypothesize that, as a result of the lying position during the night, the accumulated fluid in the lower limbs returns to the systemical circulation leading and is excreted during nighttime. This will lead to a higher voiding frequency during the night. With this trail the investigators wanst to prove the difference in leg edema between healthy volunteers and volunteers with venous insufficiency (Type 1 or 2).
This study evaluates physical properties of a innovative leg compression stocking compared to a standard compression stocking of the same compression strength in patients with chronic venous insufficiency clinical stadium C3 and above, according to the CEAP classification for chronic venous insufficiency. The physical properties can be measured through a series of measurements. The hypothesis is that the innovative compression stocking, although changed in design to be more easily donned, will perform as good as the standard compression stocking. In each participant the examinations will be conducted with both stockings. A computer generated list will allocate each participant to either one of the stockings, with which the examinations will be conducted first.
The investigators aim to evaluate the user friendliness of a newly designed leg compression stocking kit, the SOCKNLEG, compared to a standard leg compression stocking of the same compression strength, the SIGVARIS Cotton. The SOCKNLEG is not yet commercially available, whereas the SIGVARIS Cotton has been successfully commercialized for many years. After an initial screening visit, a computer generated list will allocate the participants in either the SOCKNLEG or the SIGVARIS Cotton group. All participants will try on both study stockings, in the order of their allocated group, and will rate their donning and doffing success with a questionnaire. The patients will then wear only the assigned study stocking of their allocated group, for a day and rate its comfort again at the end of the day. The donning and doffing success will also be rated by the study investigator. Leg volume measurements of the study leg will be taken at each visit to determine edema prevention.
The purpose of this study is to evaluate the effectiveness of Vasculera in reducing post procedural pain, bruising and edema in the post procedure period for patients diagnosed with C2-C5 disease requiring an intervention(s). The hypothesis is that Vasculera will reduce post procedural pain, bruising and edema for patients requiring an intervention. This will be a randomized, double-blind, placebo-controlled study. Vasculera is a specially formulated prescription medical food product for the clinical dietary management of the metabolic processes of chronic venous insufficiency. Vasculera has limited side effects, please see the product insert. A total of 110 patients will be enrolled into this study. Patients will be randomized to receive Vasculera (Study Product) or placebo. Study Product or placebo will be prescribed as one (1) tablet twice a day.
Epidermal grafts are believed to promote healing by two mechanisms: graft take and the promotion of wound healing through the delivery of growth factors and the essential elements of tissue repair and wound healing.28 This study is intended to establish the superior effectiveness of epidermal grafting and multi-layer compression over that of multi-layer compression alone, in the treatment of venous leg ulcers. Millions of Americans are afflicted with painful, open, draining sores on their lower extremities. These sores are referred to as venous leg ulcerations (VLUs). Under the best of circumstances these ulcers require weeks or months to heal. Not uncommonly wound care specialists see patients who have suffered for years or faced amputation of the limb as their only option to alleviate the pain. Standard of care will result in healing in 50% of venous leg ulcers in 12 weeks. However, roughly half of patients suffering from venous ulcers will require advanced therapy. Epidermal grafting has been a reconstructive option for decades; however, to date there has not been a reliable and reproducible system to harvest epidermis. The CelluTome® Harvesting System permits the harvesting of epidermal blister grafts at the patient's bedside without the need for anesthesia. The grafts can be easily transferred to the wound bed. In case studies, epidermal grafting appeared to be effective in reducing wound size and accelerating closure of venous leg ulcers.
This is a single center, prospective, non-randomized, feasibility study for the evaluation of safety, efficacy and performance of the Sapheon™ Closure System for the treatment of incompetent saphenous veins.
