What is Radiofrequency Ablation (RFA)?
In RFA, the walls of the defective vein is heated up until it closes and blood will now flow through all the other surrounding veins that are working properly. Through time, the treated vein will shrink and be absorbed by the body.
This entire treatment is done under the guidance of ultrasound. Under ultrasound guidance, the defective vein will be identified. A small amount of local anesthetic is injected into the skin over the vein being treated and a needle is inserted into the numbed area and into the vein. A wire is passed through the needle and up the vein. The needle is removed and a catheter (thin plastic tubing) is passed over the wire, up the vein and the wire removed. A very thin Radiofrequency wire is inserted into the catheter until its tip is at the highest point of the vein to be treated. A small amount of fluid is delivered around the vein to isolate and protect the nerve and tissue from the heat of the radiowaves. The Radiofrequency machine is then turned on and the vein is treated in segments.
After the treatment, the patient’s leg is cleaned and a compression wrap in put around the leg over the treated vein. The patient is asked to walk and stay active for the day so that the blood flow finds its new pathways. The patient may return to work or resume most of their normal daily activities.
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 calf carrying blood to the popliteal vein, which is a deep vein.
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.
Lymphedema. Lymphedema is a condition that results in swelling, typically in the arms or legs. This may be caused by a blockage in the lymphatic system or when lymph nodes are removed (as may be done as part of cancer treatment).
Generally, RFA is for larger veins. Other minimally invasive procedures may be undertaken for smaller veins.

You may be given extra anesthesia depending on the length of the treatment.
