Varicose vein interventions include radiofrequency ablation procedures and laser procedures, sclerotherapy of varicose veins in the lower extremities. The procedure is as follows: 1. Radiofrequency ablation surgery and laser surgery: both are means of varicose vein interventional treatment, by placing a radiofrequency or laser catheter into the blood vessel, the head end of the catheter generates heat and burns the endothelium of the blood vessel, damaging the endothelium and the vessel wall, and after the procedure, pressure bandage makes the wall of the vessel fit together, so as to make the lumen of the venous blood vessel occluded, and the blood will no longer flow into the varicose vein, thus closing the varicose vein. 2. Lower extremity varicose vein sclerotherapy: It is to make foam sclerosing agent by mixing polycinnamon and air 1:3, and inject it into varicose vein through balloon catheter or locally to destroy the endothelium of the vein and promote thrombosis, so as to close the varicose vein. Varicose vein intervention is a minimally invasive treatment, without incision, less traumatic, easy to operate, fast recovery, and in recent years has gradually become the first choice for the treatment of varicose veins. It is recommended that patients with the above conditions should go to regular hospitals in time and receive standardized treatment under the guidance of doctors in order to avoid delaying their conditions.
