With the RF (VNUS ClosureFast) treatment, the varicose vein in the thigh or calf is closed using radio waves. Under ultrasound guidance, the varicose vein is punctured at the height of the knee (if we are treating the thigh) or at the bottom of the calf (if we are treating the calf). An RF wire is pushed into the vein via this access. The correct position of the RF wire is determined by echo. The vein is anesthetized and then cauterized with radio waves per 6.5 cm at 120 degrees Celsius. As a result, the vein wall shrinks and the varicose vein closes. After the treatment you will be given an elastic compression stocking that you will wear for 36 hours. We already have the stocking ready for you.
