Varicose Vein Ablations

Endovenous Radio-frequency Ablation

Endovenous radio-frequency ablation is a minimally invasive procedure performed to seal varicose veins (enlarged leg veins) with heat generated from radiofrequency energy. After the varicose veins are sealed, blood starts flowing immediately to the healthy veins. Veins consist of one-way valves which prevents backflow of blood in the legs. Varicose veins are a result of blood accumulating in the veins of the legs due to leakage in the one-way valves.

Indications

Endovenous radio-frequency ablation is most commonly used to relieve symptoms of varicose veins. Symptoms include swelling, inflamed veins, discoloration, pain, skin irritation or ulceration.

Procedure

During the procedure, the doctor will apply a topical anesthetic cream over the area of varicose veins. The site of catheter insertion is numbed by a local anesthetic agent. Your doctor uses an ultrasound probe to view and track the procedure in the enlarged vein. Under the guidance of ultrasound, a catheter is inserted through a small incision in the skin and is positioned into the abnormal vein. A radiofrequency electrode is then moved through the catheter exposing the tip of the electrode at the site to be treated. After injecting the area of abnormal vein with local anesthetic, radiofrequency energy is applied at the site to seal the vein. Your doctor will apply pressure to prevent bleeding and the incised opening is covered with a bandage.

Post-procedural Care

Following the procedure, you may have to wear compression stockings to avoid formation of blood clots and to reduce bruising and tenderness. You can resume normal activities immediately. Avoid air travel and sitting for long periods during the healing phase. Ultrasound examination may be recommended during follow-ups for monitoring the treated veins and its results.  

Risks & Complications

As with any procedure, endovenous radio-frequency ablation involves minor risks and complications. They include:

Blood vessel damage

Infection, bleeding and bruising at the site of incision

Inflamed veins (thrombophlebitis)

Rarely, nerve damage or pulmonary embolism

Advantages

Advantages of endovenous radio-frequency ablation include:

Minimally invasive procedure

No visible scars

Immediate relief from symptoms

Faster recovery

It is difficult to treat twisted veins with endovenous radio-frequency ablation. The procedure is useful in treating only large varicose veins. Additional procedures such as phlebectomy or sclerotherapy may be used to treat small branched veins after ablation.
