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
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.
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.
When done by a doctor with plenty of radiofrequency experience,
chances of treatment success are good. Radiofrequency closure works well in about 97 out of 100 people who have it. That means it doesn't work well in 3 out of 100

If you are thinking of radiofrequency ablation treatment,

treatment? How much do the exam and treatment cost? How many treatments does
the doctor think you will need?
