After successful anesthesia, a 1 cm long transverse incision was made below the right groin, and the skin and subcutaneous tissues were incised to separate the main trunk of the saphenous vein, which was about 1.0 cm in diameter and locally dilated in a verrucous manner, and the branches were carefully separated and cut off one by one by ligation. The relationship between the saphenous vein and the femoral vein was identified, and the trunk of the saphenous vein was cut at a distance of 0.5 cm from the femoral vein by clamping, and the proximal end was ligated and sutured, while the distal end was left open. Another transverse incision was made above the ankle, the ankle vein was separated, the distal end was ligated, and the proximal end was placed into the stripper, which was passed smoothly through the inguinal incision, and the main trunk of the saphenous vein was completely stripped from the bottom to the top, compression was applied to stop bleeding, and the incision was closed layer by layer. In the same way, the left saphenous vein was ligated and stripped in high position, and the left saphenous vein was also stripped completely. In addition, multiple small incisions were made in both calves, and the varicose vein masses were removed with the TriVex system under dark room light conditions, filled with paralyzing swelling solution. The wound was irrigated, pressure bandaged, and returned to the hospital room after the operation. Intraoperative bleeding was approximately 30 ml.
