What this Trial Is About
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.
