Home > Be Healthy > Health Library > Varicose Veins: Radiofrequency Ablation
Radiofrequency ablation is a minimally invasive treatment for varicose veins. (Ablation means a doctor uses heat to damage tissue, which makes scar tissue form. This scar tissue closes the vein.) This technique uses radiofrequency energy (instead of laser energy) to heat up and damage the wall inside a vein. This usually closes off a varicose vein in the leg.
To treat a varicose vein, radiofrequency energy is directed through a thin tube (catheter) inserted through a small incision in the vein. It can be used on large veins in the leg and can be done in an office setting using local anesthesia or a mild sedative. You will be able to walk following the treatment and recovery typically is short.
After treatment, you will wear compression stockings for 1 week or more. To follow up, your doctor will use duplex ultrasound to make sure that the vein is closed.
Possible side effects of radiofrequency ablation include:
The more experience your doctor has had with radiofrequency, the less risk you are likely to have. Talk to your doctor about how often these side effects happen in his or her practice.
Radiofrequency ablation closes off varicose veins in about 88 out of 100 people. That means it doesn't work in about 12 out of 100 people.footnote 1
For help deciding whether to have a procedure for varicose veins, see:
If you are thinking of radiofrequency ablation treatment, consider some questions to ask about varicose vein treatment. These questions include: How much do the exam and treatment cost? How many treatments does the doctor think you will need?
