Radiofrequency Ablation (RFA)

Most often used for varicose veins like the EVLT procedure, the RFA technique uses radiofrequency energy (instead of laser energy) to heat up and damage the wall inside an incompetent vein.

Radiofrequency Ablation

Varicose veins can cause discomfort and can be unsightly. This is why you will want to consider effective treatments such as radiofrequency ablation (RFA).

RFA is an increasingly popular varicose vein treatment for being minimally invasive. But before we move forward, it is crucial to understand this term.

Ablation. It means the damage tissue is heated until it is dissolved. With the right precision, scar formation can be managed.

Radiofrequency (RF) energy. It is a form of electromagnetic energy, and is also called “radio waves”. The movement of the currents generates heat, which destroys the tissue.

What is Radiofrequency Ablation (RFA)?

In RFA, the walls of the defective vein is heated up until it closes and blood flows through a different vein. Later on, the defective vein will die and be absorbed by the body.

RFA is lot more convenient than traditional surgical interventions because it is easy and almost-painless.

First you will be asked to lie and relax. Under ultrasound guidance, the defective vein will be identified and the skin over it will be marked with a pen. A catheter will be inserted into the defective vein and then a small amount of fluid will be delivered to its surroundings to isolate it. Isolation is important to reduce the risk of affecting healthier tissues and vessels.

The radiofrequency device will be attached to the catheter so it can send radio energy to the veins. The radio energy will heat the walls of the vein to trigger its closure. Once closed, the defective vein will not receive sustenance for the blood and eventually disintegrate. This will force the blood to find a new path (a different vein).

Where Is RFA Used

RFA is often used to treat:

Great saphenous vein. This large, superficial vein is the longest in the human body. It runs along the length of your lower limb, transporting blood from the foot, leg, and thigh to the femoral vein (behind the knee).

Small saphenous vein. It is a large, superficial vein at the back of the leg.

Perforator veins. They connect superficial veins to deep veins. Varicose veins that branch out of perforated veins may be treated using foam sclerotherapy, sclerotherapy, and ambulatory phlebectomy.

Generally, RFA is for larger veins. Other minimally invasive procedures may be undertaken for smaller veins.

Do not worry because you can go on with most normal activities.

You will be asked to lie down on a comfortable bed. Afterwards, the imaging method (ultrasound) will be ran along the length of leg to locate the varicose vein. Your leg will be injected with local anesthesia and a small opening will be made into the vein. Through this opening, the catheter with radio energy source will be inserted. You may be given extra anesthesia depending on the length of the treatment.

The vein specialist might also decide to tie up or remove brand varicose veins through small incisions.
After a certain period of time, the catheter will be removed slowly. To stop any bleeding (which is usually very minimal in RFA), pressure will be applied. You may have to wear an elastic compression stocking to assist recovery and prevent complications.

  • Take care of the site where the catheter was inserted, as directed by the doctor.
  • Be watchful of signs of infection.
  • Do not take off your bandages or compression stockings unless instructed by the doctor.
  • Do not wet the catheter insertion site.
  • Elevate your legs as directed. This is to prevent blood from accumulating in the treated area.
