Filter by:To investigate the efficacy of an electrical stimulation (using the REVITIVE IX device) in treating patients with venous insufficiency.
Explorative study on a medical device with two steps. The first pilot step will be on 8 patients (4 with lymphedema and 4 with venous insufficiency). The main objective is to assess the feasibility of measures by high resolution transient elastography on these pathologic skins, and to define 3 areas for measures. The second step will be on 136 participants (48 healthy volunteers, 48 with venous insufficiency and 40 with unilateral lymphedema of a limb). The main objective is to quantify, by high resolution transient elastography, the dermal and hypodermal cutaneous fibrosis in limbs with lymphedema and venous insufficiency, and to compare it to healthy skin.
This study was designed to compare the party balloon assisted Valsalva with the conventional Valsava for exhibiting the reverse venous flow in superficial venous valvular incompetence duplex examination.
Chronic venous insufficiency (CVI) is a common disease affecting mainly lower limbs leading to significant impact on the quality of life. There is no study, to our knowledge, has attempted to evaluate the impact of compression stockings on all patients with CVI. Our aim is to estimate the prevalence of CVI in Qassim Region and to test the effectiveness of compression stockings.
The purpose of this study is to determine the ease of use and comfort of the ACTitouch dual action pneumatic compression device in patients with unilateral or bilateral chronic venous insufficiency (CVI) with or without venous leg ulcers, as compared to standard compression.
At 3 months, crenobalneotherapy session is superior to waiting list for patients with chronic venous insufficiency.
The purpose of this study is to compare functional status and quality of life of a group of patients with chronic venous insufficiency treated with manual lymphatic drainage with a group not treated with manual lymphatic drainage. Investigators hypothesized that manual lymphatic drainage can improve: - quality of life, - functional status, - calf muscle strength, - ankle range of motion, - edema, - severity of disease, - and symptoms.
The purpose of this study is to evaluate the efficacy and safety of the fixed-dose combination of coumarin and troxerutin versus placebo in the symptomatic treatment of chronic venous insufficiency.
Problem: Approximately 4 million live births occur in the United States each year. Pregnancy causes many physical changes in the mother, including venous distension, increased ability to form blood clots, and hormonal changes. Data suggest that these factors help cause venous insufficiency (when the veins do not adequately return blood from the extremities to the torso). As venous insufficiency progresses, complications follow, the most severe of which include superficial thrombophlebitis and deep venous thrombosis (DVT, or blood clots). Although the fear of DVT has been well publicized, its prevention and prevalence in pregnant women has not been well-studied. The exact cause of venous insufficiency is not known. However, known risk factors include being female and hormonal changes associated with oral contraceptive use, certain hormone replacement medications, and pregnancy. Being pregnant places the mother at additional risk for developing venous insufficiency. Compression stockings are used to manage the condition, but this is by no means standard of care despite their easy use and safety. The medical community's understanding of how compression stockings work is largely theoretical; however, it is believed that the compression works by preventing venous hypertension in the lower legs, thereby preventing venous insufficiency and its associated complications. Research hypothesis: The investigators hypothesize that compression stocking use will be associated with lower incidence of varicose veins and, in those patients who already have varicose veins, lower incidence of complications associated with venous insufficiency. Further, the investigators believe that compression stocking use will be associated with a lower incidence or lessening of symptoms associated with venous insufficiency. Importance: An undetected DVT can be fatal. Even if detected promptly, DVT is associated with long term health problems. Treatment of a DVT requires anticoagulation which can be risky to both mother and fetus. The prevention or reduction of DVT in pregnant women through use of compression stockings would revolutionize their care. Further, this intervention is safe and noninvasive. The investigators propose to conduct a randomized, pilot study comparing pregnant women without and with varicose veins randomized to wear compression stockings to a similar group of participants randomized to no compression stocking use.
Endovenous ablation of the greater saphenous vein has nowadays the same outcome as open crossectomy and stripping. The two most performed techniques for endovenous ablation are the endovenous laser ablation and the radiofrequency ablation. According to the trial of Rasmussen, they are equivalent for occlusion but the lower laser wave lengths resulted in more pain and paresthesia. The newer wave length of 1470 nm showed lesser side effects in observational studies. The aim of this study is to compare radiofrequency ablation with the VNUS closure fast ® with laser ablation with a 1470 nm wave length in combination with a new fiber, the Tulip fiber ®. This fiber has the shape of a tulip at his tip which avoids point necroses of the vessel wall and on consequence results in lesser side effects from wall perforations such as pain, haematoma,…
