Minimally invasive surgical methods for varicose veins include laser, radiofrequency ablation, etc., which is used to treat varicose veins by damaging the walls of the blood vessels and then causing them to close. Varicose veins are common in laborers who stand for long periods of time and are caused by the backflow of venous blood. For patients with varicose veins, surgery can be considered as long as the diagnosis is clear and there are no corresponding contraindications. In recent years, minimally invasive procedures for varicose veins have been widely performed, including laser and radiofrequency ablation. The principle of both laser and radiofrequency ablation is to use thermal ablation to destroy tortuous blood vessels, causing them to fibrose and then the blood vessels to close, stopping the backflow of blood and achieving the therapeutic effect. Generally speaking, the catheter is inserted under ultrasound guidance, local anesthesia is injected, and then laser and microwave are emitted to cause cell necrosis of the inner wall of the blood vessel. After the operation, the affected limb is well bandaged so that the blood vessel wall can be tightly closed. Specifically need to be operated by specialized physicians.
