Calcium Dobesilate After Radiofrequency Ablation for Varicose Veins

This study evaluates whether calcium dobesilate, a venoactive drug, improves recovery after radiofrequency ablation (RFA) for varicose veins. Patients with great saphenous vein insufficiency undergoing RFA will be randomly assigned to receive either calcium dobesilate (500 mg twice daily) or standard care alone. The treatment starts 7 days before the procedure and continues for 30 days after. The primary outcome is postoperative pain at day 7. Secondary outcomes include pain at days 14 and 30, quality of life, ecchymosis, and return to daily activities.
