How does radio frequency closure treat varicose veins?

Radiofrequency closure (also called radiofrequency ablation, RFA) is a minimally invasive treatment for varicose veins. It uses radiofrequency energy to heat and damage the diseased vein, causing it to collapse and seal shut.

Here's how radiofrequency closure works:

1. Preparation: The patient lies down on a treatment table, and the affected leg is cleaned and shaved. A local anesthetic is injected to numb the area around the varicose vein.

2. Insertion of the catheter: A thin, flexible catheter is inserted into the varicose vein through a small incision. The catheter is guided into place using ultrasound imaging.

3. Delivery of radiofrequency energy: Once the catheter is in position, radiofrequency energy is delivered through the catheter. The energy causes the vein walls to heat up and damage, leading to the collapse and sealing of the vein.

4. Withdrawal of the catheter: After the radiofrequency energy has been delivered, the catheter is slowly withdrawn from the vein. The skin incision is closed with a small bandage or adhesive strip.

5. Compression: A compression stocking is placed over the treated leg to help keep the vein closed and promote healing.

Radiofrequency closure is typically an outpatient procedure, meaning the patient can go home the same day. The treated leg may be bruised or swollen for several days, and some discomfort may be experienced. Most people return to their normal activities within a few days.

The success rate of radiofrequency closure is high, with a low risk of complications. It is an effective treatment for varicose veins and can improve symptoms such as pain, swelling, and visible spider veins.
