RadioFrequency Ablation (RFA) (1)

1. What is the Radiofrequency Ablation of Varicose Vein?

RFA a minimally invasive treatment alternative to the traditional vein stripping surgery for varicose veins and gives better cosmetic results with less scarring. The principle is that by removing the abnormal vein by applying radiofrequency energy inside the vein (‘endovenous’) to destroy (‘ablate’) it.

2. How is RFA done?

The procedure is performed on an outpatient basis with the patient awake. The entire procedure is done under ultrasound visualisation. After a local anaesthetic is injected into the thigh area, the laser fibre is threaded into the vein through a small puncture hole. Then radiofrequency energy is released which heats up the wall of vein and causes it to collapse. Radiofrequency energy is released continuously as the fibre moves along the whole length of the diseased vein, resulting in the collapse and ablation of the varicose vein. Following the procedure, a bandage is placed over the entry site, and additional compression is applied. Patients are then encouraged to walk and resume all normal activities

3. How is RFA of varicose vein different from conventional surgery?

RFA does not require general anaesthesia and is a less invasive procedure than vein stripping. The recovery period is also shorter than surgery. Patients usually have less post-operative pain, less bruising, faster recovery, fewer overall complications and smaller scars.

What a Varicose Vein Looks Like After a Phlebectomy

 

 
Appears smaller, because the vein contracts and there is no blood flowing through it. This is what a varicose vein looks like after it is removed by phlebectomy. The needle points to the ballooning of the vein (dilatation). This commonly occurs just after the valve, which is not functioning properly. The bulges you see under the skin, in many instances are the dilated areas the needle is pointing to.

Varicose Vein Treatment

Common Treatment Options for Varicose Veins

The commonly used treatment options for varicose veins include; compression therapy, thermal ablation, sclerotherapy, phlebectomy and high ligation and stripping. It is important to familiarize yourself with these treatment types and then discuss the best option with your doctor. Most experts in the field of venous disease consider thermal ablation to be the safest, simplest, and most effective treatment type in producing the best long-term results when treating GSV or SSV problems.

Compression Therapy

This conservative treatment is aimed at wearing compression stockings. While this may alleviate some of the symptoms of varicose veins, it does not stop progression of the venous disease. Compression is measured in mmHg. Most people cannot tolerate more than 30 mmHg for prolonged periods of time. Compression therapy is typically used to temporarily relieve symptoms associated with varicose veins and is not a long-term solution to the underlying problem.

Thermal Ablation

This is done with either a laser or radio frequency (RF) catheter. The aim of both of these treatments is it to destroy the vein from the inside using heat. This requires a local anesthetic and an ultrasound. A small needle puncture is made in the saphenous vein. A guide wire is introduced through the needle and over this wire a catheter is placed. The catheter allows for the insertion of the laser filament or (RF) catheter. The filament is directed to just below where the saphenous vein comes off of the femoral vein (3cm below). Next the tumescent solution is placed around the saphenous vein and the laser is then activated and gradually pulled back along the course of the vein. A slightly different technique is used with RF. This heat damages the inside of the vein and over a period of time the vein scars and disappears.


Complications are possible with any medical procedure, however, are rare with thermal ablation. There is a very low incidence of deep venous thrombosis (clot) - (DVT) and infections and skin burns are very rare. Most patients have minor issues such as bruising and discomfort in the thigh. Walking soon after a treatment is encouraged. Tumesecent anesthetic is a very dilute solution of xylocaine, sodium bicarbonate, and epinephrine and in most patients, less than 500 cc is needed. A safe dose is over 3 liters.

In this photo, the catheter is placed in the saphenous vein. You can see the laser filament here just before it is placed in the catheter. Once the filament has been placed, tumescent solution is placed around the vein and laser firing begins.
