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.

Observation of Pain During the Treatment of Great Saphenous Vein Using Microwave Ablation， and Analysis of Related Factors
Objective: This study is a single-center prospective observational research that recorded patients' pain scores at four time points during surgery (puncture and catheter insertion, swelling fluid injection, microwave generator operation, and end of surgery). It analyzed the correlation between pain during microwave ablation treatment for great saphenous vein varicosities and factors such as age, gender, body mass index, volume of swelling fluid used, and others, in order to summarize and improve surgical details to reduce patients' intraoperative pain.
