Filter by: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.
Leaking valves in the veins of the legs causes veins to become large and bloated. These swollen veins are called "varicose veins" and are a very common problem, affecting more than a third of all adults in the UK. Varicose veins reduce people's quality of life by causing problems such as pain, itching and restless legs. Varicose veins may also damage the skin over time causing problems such as bleeding, skin colour changes, eczema and even break-down in the skin which is called an ulcer. Newer, "key-hole" methods of treating leaky veins have been developed as an alternative to surgery and can be performed under local anaesthetic with the patient awake. Rather than cuts in the skin, these minimally invasive techniques are performed through tiny stab wounds; little larger than needle holes. The varicose vein is then destroyed from within, usually using heat to burn the inside of the vein. These procedures are popular; with a rapid recovery and a very high success rate. However these methods also require the vein to be surrounded by a large volume of dilute local anaesthetic which can to be slightly painful to administer. A technique called "Foam sclerotherapy" involves the injection of a drug which has been mixed into a foam. This goes into the vein and causes it to stick shut. This procedure is near painless to perform as very few, small local anaesthetic injections are required; however the chance for a successful treatment first time are lower and patients may need to return for repeat treatments to successfully treat the vein. The aim of this study is to see whether the success rates for this technique can be improved. One method "catheter directed foam sclerotherapy" involves the delivery of the foam through a catheter (a long very thin tube), so that large lengths of vein can be treated through a single hole. The final method "ClariVein" again uses a catheter; but this time the catheter has a small wire on the end which spins around inside the vein; similar to an edge strimmer in the garden; except it irritates the vein: rather than cutting it. This irritation makes the vein more susceptible to the drug which can again be applied directly to the vein wall whilst it is still active. Early results show that this final method is very successful; however the equipment is more expensive than for the other two. This study will randomly allocate willing participants with varicose veins to receive one of these three treatments to see whether the two newer treatments can improve the success rates and quality of life improvements seen with foam sclerotherapy, whilst also allowing near painless treatment, without significant complications, at an appropriate cost.
There is a difference concerning obliteration rate and postoperative pain after treatment of the saphenous vein with 1470nm laser or VNUS Closure Fast (=radiofrequency method) .
At 3 months, crenobalneotherapy session is superior to waiting list for patients with chronic venous insufficiency.
The aim of this study is to identify whether the treatment of pelvic venous reflux (pelvic coil embolisaton) in females with leg varicose veins, who have a proven contribution to their leg varicose veins from pelvic reflux, have a reduction in recurrence after varicose vein surgery.
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,…
Randomized controlled trial, a method used to implement the random allocation sequence is numbered containers. The aim of the study is to compare compression therapy with compression stockings and surgery eliminating superficial venous reflux in patients with duplex ultrasound verified superficial venous reflux without skin changes or ulceration.
