Filter by:EVLA is used in in treating refluxing veins, commonly the GSV. The tip of catheter is usually placed 2-2.5 cm distal to the sapheno-femoral junction. This technique theoretically provides the lowest risk for endothermal heat-induced thrombosis (EHIT). In the present study we aimed to evaluate the zero-distance technique (the kissing technique) compared to 2-cm distance from SFJ valve in ablating incompetent GSV.
Assessment of the Relationship between Severity of Chronic Venous Obstruction and Venous Claudication
The purpose of this study is to evaluate whether adding sulodexide to the patients with varicose veins who received radiofrequency ablation combined with sclerotherapy can reduce or improve the impact of adverse events。
Randomized Controlled Trial to determine if the outcomes of sclerotherapy of the ulcer bed alone differ from a combination of ablation and sclerotherapy injections.
To demonstrate that the Insight Pro Device is safe and effective for use in detecting lymphatic and venous disorders.
The National Varicose Vein Study is a cross-sectional, multicenter, observational study. The primary goal is to evaluate the 30 days outcome of the conventional great saphenous vein surgery (stripping) in the treatment of the symptomatic chronic venous insufficiency, comparing the results of difference Portuguese's health centers, comparing the following variables: thrombo-prophylaxis (pharmacology or mechanic; compliance); antimicrobial prophylaxis; quality of life; medication compliance; complications and work incapacity period.
Chronic obstruction of the iliac veins or inferior vena cava can occur as a result of deep vein thrombosis (DVT), or due to extrinsic compression in non-thrombotic iliac vein lesions (NIVLs). This obstruction can manifest as post-thrombotic syndrome (PTS) after DVT or as chronic venous disease (CVD) in NIVL. Despite sparse evidence, rates of venous stenting for PTS and NIVLs are increasing. A pragmatic, observer-blind, multi-centre, randomised-controlled trial for adults with CVD secondary to either PTS or NIVLs randomised to either best endovenous therapy (including venoplasty and deep venous stenting) or standard therapy (compression +/- anticoagulation). Included participants will have chronic venous disease (CEAP classification 3 - 6) secondary to proximal deep venous disease. The primary outcome is severity of venous disease at 6 months as ascertained by the Venous Clinical Severity Score (VCSS).
Compression wraps treat venous leg ulcers when applied correctly. Often, clinicians apply the wraps at the wrong compression, or the wrap loosens, stopping clinical benefits. The study aims to show the feasibility of a smart compression prototype to maintain a set compression level in healthy volunteers. Each volunteer will wear the prototype device on one leg and a standard compression wrap on the other. Volunteers will pump their calves, walk, lie down, and stand at zero, one, and four hours. A pressure sensor placed over each calf will record the compression level during the activities. Volunteers will provide subjective feedback on each device concerning comfort and usability. After four hours, researchers will remove the standard wrap. Volunteers will use the prototype device during daily activities for three days. During the three days, the volunteers will complete a daily journal. The journal will capture the user experience and time the volunteer used the device. A final site visit allows researchers to conduct exit interviews and download the history of applied compression. Researchers will use the data to show that the prototype device maintains therapeutic compression and prove the usability of the device.
The present study aims to use a game-based tele-exercise program for patients using a compression garment to improve lower extremity edema. This tele-exercise gaming platform can work as an efficient exercise to improve patients' muscle strength. It also can be helpful in improving edema and venous return and can be used in addition to compression garments to increase efficacy. The sample size (n=30) is convenient and designed to explore acceptability and feasibility. Eligible participants will be screened at the Baylor college of Medicine Clinic based on the inclusion/exclusion criteria. Participants who satisfy the inclusion and exclusion criteria and sign the informed consent form will be randomly assigned with ratio of 1:1 into two groups. Both groups will receive a compression garment to use for 4 weeks, and in the intervention group, patients will receive a sensor and a tablet to play foot & ankle exercise games twice a day for 5 minutes. Study participation will be 4 weeks for all participants. Participants will be assessed in two visits: a baseline visit (BL) and a visit at the end of the 4 weeks (W4). The primary outcomes will be calf circumference, foot volume, and pitting edema grade. Secondary outcomes include limb strength, foot perfusion, gait assessment (gait speed, stride length, double stance, and gait steadiness), balance, and quality of life. The coordinator will monitor patients weekly to see their adherence to the compression garment and game-based exercise.
