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.
• Age≥ 18 years old, ≤ 90 years old;
• the patient's life expectancy is greater than 12 months;
• The clinical diagnosis is primary VVs, CEAP classification C2-C6, and the GSV segment needs to be treated, including pain, burning sensation, heaviness, fatigue, itchy skin, night cramps and other clinical symptoms;
• Doppler ultrasound confirmed that the diameter of GSV was greater than 3mm and less than 12mm when standing;
• Doppler ultrasound confirms that GSV is located in the saphenofascia or the distance between GSV and the skin surface is \>1cm;
• endovenous microwave ablation treatment only for unilateral GSV walking area;
• The patient is willing to cooperate with the completion of the examination specified in the protocol.
