Clinical Outcomes, Safety, and Cost-Effectiveness Analysis of Two Catheters (Xianrui Da and Medtronic) in Radiofrequency Ablation for Varicose Veins

This study aims to systematically compare the clinical efficacy (venous closure rate and symptom relief rate), safety (perioperative and postoperative complications), and cost-effectiveness (direct medical costs) of domestic Xianruida radiofrequency catheter and imported Medtronic catheter in endovenous radiofrequency ablation for varicose veins through a single-center, prospective, non-inferiority randomized controlled trial.
