Comparative Analysis of Radiofrequency Ablation and Microwave Ablation Procedures for the Treatment of Small Saphenous Varicose Veins

During the procedure, 2% lidocaine was injected subcutaneously along the course of the saphenous vein under ultrasound guidance, and after local anaesthesia, an incision was made at the ankle joint of the saphenous vein to locate the saphenous vein, and a radiofrequency guidewire and catheter sheath were introduced.The saphenous vein was incised at the ankle joint under local anaesthesia. Under ultrasound monitoring, the radiofrequency catheter was placed in the saphenous popliteal vein at a distance of 1\~2 cm and the position of the catheter was fixed, and then anaesthesia and swelling fluid was injected into the fascial tissues around the main trunk of the small saphenous vein in segments.The two groups were treated with radiofrequency ablation and microwave ablation surgery, respectively.
