Radiofrequency Ablation (RFA)

No More Veins …. Is a Promise

What is Radiofrequency Ablation (RFA) Treatment?

Radiofrequency (RF) endovenous ablation is a minimally invasive treatment procedure for venous reflux disease.

Using radiofrequency to heat and seal diseased great saphenous and perforator veins and address the underlying cause of severe varicose veins. The procedure uses radiofrequency energy to heat and cauterize damaged or weakened veins.

When your damaged vein is closed, your varicose veins fade away, and your blood is forced to move through healthier veins on its journey back to your heart and lungs.

Walking is the best exercise

How Does Radiofrequency Ablation (RFA) Work?

  • The procedure is done in the clinic using local anesthesia at the site of the procedure
  • The catheter is inserted into the diseased vein
  • The catheter delivers radiofrequency waves energy into the vessel in 20-second intervals. This heats the walls of the vein in 7 cm increments and causes it to collapse.
  • The ablated vein becomes scar tissue and eventually is later absorbed by the body.
  • The same procedure is done on the other leg too if both legs would undergoing treatment.
  • The procedure takes 20-30 minutes for one leg.
  • The catheter is then removed and the catheter insertion site is covered with a medical bandage.

  • After that you may shower. Remove the gauze dressing and wipe the entry site with antiseptic alcohol or betadine. Cover with band-aid until healed
Prescribed medications for pain will be provided if needed

A written prescription may be provided for pain medication to be taken as needed.

Schedule A Follow Up Visit
Follow Up
  • Schedule your follow-up visit and Duplex (ultrasound) scan within 2 weeks after your procedure.
  • Bruising and redness is normal. You may also feel a tugging sensation for the first week after the procedure. Sometimes people can feel a hard area like a pencil under the skin especially around the knee. This is normal and will go away in a few months.

We know you have some questions and concerns, We Have The Answers

The  RF procedure typically takes approximately 45-60 minutes.

The RF procedure is performed in iVein Clinic under local anesthesia without the need for hospitalization or anaesthesia.

After the procedure, you will be able to walk immediately. Many patients experience a quick return to normal activities, typically within a few days. For a few weeks following the treatment, we recommend a regular walking regimen and suggest you refrain from very strenuous activities (i.e., heavy lifting) or prolonged periods of standing.

Most patients report a noticeable improvement in their symptoms within one to two weeks following the procedure.

Although it is possible to experience pain, bruising or tenderness after treatment, many patients report minimal to no scarring, bruising or swelling following the RF procedure.

Most insurance companies pay for the RF procedure in part or in full. iVein Clinic has coverage policies with major health insurers.

Both are minimally invasive techniques that can treat varicose veins. Both use heat to obliterate diseased veins.  And both provide better results compared to surgery. However, there are some technical differences between the two procedures.

Laser catheters are generally more slim and more flexible than RF catheters which makes it technically slightly superior in small caliber veins as well as more tortuous veins. Also the end firing tip in laser rather than the 7 cm heat coil in radiofrequency, makes laser more suitable for short veins and perforators as well.

Although both laser and radiofrequency varicose vein ablation proved effective and are superior to traditional surgical methods, the laser is slightly better than radio waves due to some technical factors.
