Study Comparing Ultrasound-Guided Radiofrequency and Microwave Ablation for Treating Small Saphenous Varicose Veins

What this Trial Is About

This research aims to compare the clinical effectiveness of two minimally invasive treatments, ultrasound-guided radiofrequency ablation and microwave ablation, for primary small saphenous varicose veins, a type of chronic venous insufficiency affecting the lower limbs. Small saphenous varicose veins are less common but more challenging to treat due to their anatomical connection to the popliteal vein and the risk of nerve injury with traditional surgery. The study addresses the need for safer, less invasive options with fewer complications and better recovery. Participants will receive either radiofrequency ablation or microwave ablation, both performed under local anesthesia with ultrasound guidance. The procedure involves injecting anesthetic along the vein, making a small incision near the ankle, and inserting a catheter to deliver energy to close the affected vein. Patients will be monitored for postoperative recovery, including length of hospital stay, time to mobilization, pain scores, and complications. Follow-up with Doppler ultrasound will occur at 2 weeks, 1 month, and 3 months to check for vein closure and recurrence. Quality of life and symptom assessments will be conducted using standardized scoring systems. During the study, participants will undergo several evaluations including clinical symptom assessments, venous ultrasound imaging, and questionnaires on venous disease impact and quality of life. The primary outcome is the vein occlusion rate at 6 months after surgery. Researchers will also track complications and the effectiveness of each treatment over time. The total participation period includes these follow-ups and assessments to ensure safety and monitor long-term treatment success.
