Filter by:In this project, an exploratory study was conducted to perform in situ venous valve remodeling in vivo, evaluate venous valve function after surgery and conduct regular follow-up, collect relevant ultrasonic data before, during and after surgery, and evaluate the safety and effectiveness of Ultrasound-guided percutaneous great saphenous vein valve functional remodeling.
The aim of the study is to evaluate the ability of Doppler ultrasonography of the portal vein and liver stiffness measurement using Transient Elestoghraphy in predicting prescence of gastroesophageal variceal and variceal bleeding in patients with liver cirrhosis
Research has proven that large varices can be treated with beta-blockers (a type of anti-hypertensive medication) to reduce the pressure in the veins. The management of small varices is still uncertain. This study aims to discover if beta blockers can be used in this setting. We hypothesize that beta blockers will reduce the risk of bleeding from small varices from 20% to 10% over a period of 3 years, resulting in significant cost savings to the NHS from better patient outcomes.
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.
The number of patients with lower extremity varicose veins has been increasing due to an aging population, with treatments divided into conservative and invasive methods. Current treatments can be expensive and inaccessible for some patients. Entelon, a relatively inexpensive intravenous drug, has shown promise in improving symptoms related to venous lymphatic dysfunction, but its objective vascular function improvement hasn't been proven. This study aims to assess the effectiveness of Vitis Vinifera seed extract (Entelon®) combined with lifestyle therapy in patients with varicose veins, using follow-up Doppler ultrasonography to measure venous reflux improvement.
A prospective, multicenter, non-inferiority, randomized controlled trial is designed to evaluate the effect after short-term compression therapy following thermal ablation of varicose veins. Patients will be randomly assigned in a 1:1 ratio to one of the following treatments: (A) elastic bandage for 48h or (B) elastic bandage for the first 24h and then a compression full-length stocking (23-32mm Hg) for 1 week. The two groups will be compared on several variables, including target vein occlusion rate at 3 months (primary outcome indicator) , as well as pain, quality of life, clinical severity of varicose veins, postoperative complications, time to return to normal work, and compliance.
The aim of this study is to use non-invasive methods to identify patients at risk of developing gastrointestinal varices and correlation of these non-invasive methods with the degree of esophageal varices and the presence or absence of risk signs of bleeding such as cherry red spots.
Endovenous interventions are keyhole operations for varicose veins that are carried out from within the vein itself. Varicose veins are enlarged veins close to the surface of the skin. They are connected to the bigger deeper veins in the leg (known as deep veins). Because of this, operations to close the varicose veins can increase the chance of a blood clot forming in the deep veins. Blood clots in the deep veins happen in around 1 in 50 people after endovenous operations. A clot in the leg can cause swelling, pain, and other long-term problems. If a clot in the leg breaks off and travels to the lungs, it can cause problems with the lung' ability to move oxygen from the air into the blood and may, in rare cases, be life threatening. Varicose vein procedures may carry a slightly higher risk of blood clot formation, and we are currently unsure if current clot reducing medicines are beneficial in preventing blood clots in people having varicose vein procedures. This study will investigate if it is worthwhile prescribing medicines to reduce blood clots after varicose vein procedures.
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.
