Filter by:our aim is to compare early outcomes following EVL 1320 nm and segmental RF in a randomized study.
It will be done a randomized triple-blind study comparing 0,2% polidocanol versus 75% hypertonic glucose of sclerotherapy in lower limbs´ reticular veins. It will be included only adult women with reticular veins on the side of the thighs and mild venous insufficiency (CEAP 1). The primary endpoint will be efficacy, and secondary will be safety.
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.
Endovenous laser ablation is a common therapy of great saphenous vein insufficiency with a very high success rate. It works by heating and thereby obliterating the vein. Steam ablation is a new therapy that also works by heating and thereby obliterating the vein. The hypothesis of this study is that steam ablation is as effective as laser ablation, but that it results in better secondary outcomes (e.g., lower pain scores).
Varicose veins of the leg often have superficial tributaries, which are often symptomatic and a major reason for coming to the doctor. When treating the main varicose vein inside the leg, some doctors prefer to remove these tributaries while others prefer to leave them. This trial aims to see if it is better to remove these veins at the time of the first laser procedure or better to leave them and only remove them when asked.
The purpose of this study is to compare two therapeutic procedures in the treatment of isolated varicosis of the anterior accessory great saphenous vein (AAGSV): crossectomy and avulsion of the varicose AAGSV versus foam sclerotherapy of the AAGSV.
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.
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.
Randomized comparison within the endoscopic esophageal varices ligation versus non-selective beta-blocker in the primary prevention of esophageal variceal bleeding in patients with HCC.
The aim of this randomised case-controlled trial is to investigate whether ablation of incompetent perforating vein in addition to ablation of truncal vein reduces the rate of recurrent varicose veins post-treatment compared with patients who only have ablation of the truncal vein, who are left with untreated incompetent perforating veins.
