Observation of Pain During the Treatment of Great Saphenous Vein Using Microwave Ablation， and Analysis of Related Factors

Sponsor

Chengdu University of Traditional Chinese Medicine

Enrollment

155 participants

Start Date

Dec 1, 2024

Study Type

OBSERVATIONAL

Conditions

Vascular Disease，Peripheral Venous Insufficiency of Leg Varicose Veins of Lower Limb

Summary

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.

Eligibility

Min Age: 18 YearsMax Age: 90 Years

Interventions

PROCEDUREVAS scores of the puncture

All patients were evaluated by our team with CEAP grading and ultrasound measurements to record the diameter of the saphenous vein before surgery。We performed endovenous microwave ablation of the great saphenous vein along with foam sclerotherapy and point stripping treatment. We documented the operating room temperature, puncture site, VAS scores during puncture and catheter placement, the amount of injected tumescent fluid, radiofrequency generator used, and data at the conclusion of the surgery. A descriptive analysis of intraoperative pain scores was conducted to evaluate the level of pain experienced during the surgery. A nonparametric test was utilized to analyze the relationship between preoperative and intraoperative factors and the level of pain experienced during the surgery.
