Effect of Vitis Vinifera Seed Extract on Venous Reflux Time in Varicose Vein

Summary

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.
