Filter by:Primary prophylaxis of gastric varices is an important area of research, as gastric varices are a common complication of cirrhosis of the liver. Cirrhosis is a condition in which the liver becomes scarred and loses its ability to function properly, and it is a leading cause of morbidity and mortality worldwide. Gastric varices occur in up to 30% of patients with cirrhosis, and they can rupture, leading to life-threatening bleeding. The clinical, epidemiological, and public health context of primary prophylaxis of gastric varices is therefore the need to prevent the development of this complication in patients at risk for cirrhosis and to reduce the associated morbidity and mortality. The clinical trials on primary prophylaxis of gastric varices are therefore focused on evaluating the safety and efficacy of various interventions, such as beta-blockers and endoscopic techniques, in reducing the risk of gastric varices in patients with cirrhosis. The goal of this trial is to find the most effective and safe strategies for primary prophylaxis of gastric varices, in order to improve the outcomes for patients with cirrhosis.
Endoveinous treatment of saphenous varicoses and phlebectomia of tributary veins are commonly performed under local anesthesia. Hypnoanalgesia might reduce perinterventional pain. This study has the aim to test the effectiveness of hypnoanalgesia, performed by a specialised nurse, for peri-and post-procedual pain reduction.
A new technique, mechanochemical endovenous ablation (MOCA), using the ClariVein ® system is recently developed. To date, histopathological data after mechanochemical endovenous ablation are not known. The aim of this study is the histopathological analysis of venous injury using mechanochemical endovenous ablation.
This study evaluates the addition of polidocanol endovenous microfoam (PEM) to compression therapy to determine effectiveness in improving the healing of venous leg ulcers (VLUs) in adults with severe venous disease of the great saphenous vein (GSV). All participants will receive treatment with Varithena and compression therapy. The purpose of this study is to assess whether the use of PEM to correct superficial axial and varicose vein reflux is effective in improving healing of VLUs, over treatment with compression alone.
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.
In this proposal, the investigators seek to determine whether a reduced compression after endovenous ablation procedure in treating superficial venous insufficiency affects the outcomes. This study involves only the use of the compression stocking post endovenous ablation procedure and everything else is standard according to current guidelines. The investigators general strategy will be to determine the role of a minimal post-operative compression and the status of patient satisfaction including (1) Success closure rate of the treated vein. (2) Less pain; (3) Easier accepted by the patients.
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.
Evaluate the safety, tolerability and effectiveness of mucopolysaccharide polysulfate cream in the treatment of superficial varicose veins
Evaluate the safety, tolerability and effectiveness of mucopolysaccharide polysulfate in the treatment of superficial varicose veins
This is a multi center, randomized, comparison study using two already cleared methods of treatment of the great saphenous vein (GSV). The hypothesis to be tested is that the use of the Venacure EVLT NeverTouch procedure is no worse than the RF ClosureFAST procedure for treatment of the GSV. Evaluation of post operative pain and bruising, quality of life assessments, adverse event assessments, confirmation of long term GSV closure, use of medications are criteria that will be evaluated during the course of this study.
