Radiofrequency ablation of varicose veins is performed outpatient and does not require general anesthesia.
First, the patient’s leg is anesthetized to prevent pain. Then the doctor will insert a thin tube (catheter) through a small incision in the vein. The catheter is then heated by passing an electric current through it to destroy the vein from the inside. After the treatment, the incision is closed, and a compression bandage is applied.
