Observing pain during microwave treatment for varicose veins

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess pain levels experienced by patients undergoing microwave ablation for great saphenous vein varicosities at various stages of the procedure. It records pain scores at four key time points during surgery and analyzes how factors such as age, gender, and body mass index correlate with intraoperative pain. The goal is to identify ways to improve surgical techniques and reduce pain for patients undergoing this treatment. By focusing on the patient's experience, the study seeks to enhance the overall quality of care in vascular surgery.
