Active clinical trials for "Varicose Veins"

Hypothesis. Regular using of Class 1 below-knee graduated compression stockings (RAL GZ 387 standard) compared to the absence of elastic compression will reduce the risk of clinically significant varicose veins recurrence at 12 months after endovenous thermal ablation of the great saphenous vein and elimination of varicose tributaries.

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 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.

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.

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.

VelexTM Venous Catheter is a venous catheter for temporary use to treat a vein isolated segment, designed for the treatment of varicose veins of lower limbs by means of chemical ablation or empty-vein sclerotherapy. V.A.S.C. is a multicentric, prospective, open label, non-randomized PMCF study of VelexTM venous catheter used according to the indication of use within the scope of the CE mark. VelexTM venous catheter is intended for patients with varicose veins of lower limbs. The total minimum number of patients is 24 and the maximum 36 for the two centers participating. Each center shall enroll at least 8 patients andno more than 28.

This study evaluates the safety and efficacy of 24-hour vs 72-hour octreotide infusion after variceal banding in cirrhotic patients with bleeding esophageal varices.

The purpose of this study was to evaluate the efficacy and safety of microwave ablation catheter in the treatment of varicose veins in lower extremities,meanwhile, to compare the quality of subjects'lives before and after treatment.

This study will be comparing the treatment of varicose vein tributaries using either foam sclerotherapy or ambulatory phlebectomies. Patients will be randomised to having either ambulatory phlebectomy (group A) or foam sclerotherapy (group B) following treatment of their saphenous vein. The re-intervention rates, safety, patient experience as well as the cost effectiveness of each intervention will be assessed.

Balloon-occluded retrograde transvenous obliteration (BRTO) has been effective method to manage gastric varices. However, more than one third of patients after BRTO treatment experienced worsening of esophageal varices. The present study was designed to evaluate the effect of post-BRTO propranolol adminstration on the change of esophageal varices.
