Title: Venous Ulcer: Endovenous Radiofrequency Treatment of Insufficient Perforating and Saphenous Veins Versus Multilayer Compression Bandaging - Randomized Controlled Clinical Trial
Brief Summary: The aim of this study is to analyze the effect of intravenous therapy with radiofrequency for superficial and perforating venous insufficiency versus compression therapy with multilayer banding in patients with active venous ulcer. This is a controlled, randomized prospective clinical trial. People with venous ulcers and primary venous insufficiency in superficial and perforating venous system will be studied. Participants will be divided into two experimental groups: compression therapy alone, and compression therapy associated with superficial and perforating venous system ablation. Clinical aspects, improvement in patients' quality of life and interventions cost-effectiveness will be analyzed. Patients will be followed for 12 months after ulcer healing.
