The common procedures for varicose vein surgery in lower limbs are endovenous laser cauterization, saphenous vein flap surgery and radiofrequency ablation therapy. 1. Endovenous Laser Cautery Closure Surgery: Vein closure surgery involves laser thermal ablation to close the blood vessels, thus eliminating venous reflux. This procedure is less invasive, less painful during recovery, and shows fewer symptoms of hematoma and paralysis. 2. Saphenous Valve Surgery: Open vein surgery, including venous valvuloplasty, vein valve grafting or transposition, and fresh and cryopreserved homograft valves are the most widely used biosynthetic replacement valves. 3. Radiofrequency ablation therapy: Semiconductor laser therapy is a surgical procedure that is different from stripping the trunk, and can be completed by endovascular treatment, which minimizes the damage, does not leave surgical scars, and reduces the pain of the patient, making it easier to accept. Varicose veins are most commonly seen in long time standing and need attention in life. Active surgical treatment is recommended to fulfill the indications for surgery.
