Treatment of varicose veins without surgery: The development of Interventional Radiology has allowed the use of guided techniques with ultrasound that have many advantages over classical surgery in the  treatment for varicose veins . The advantages of percutaneous techniques in the treatment of varicose veins are less aggression to healthy tissues (fewer bruises and scars), procedures performed under local anesthesia (not general or epidural), ambulatory (without hospital admission), with immediate incorporation into their daily activities (without work absence) and with a much lower incidence of complications.
