Radiofrequency Ablation (RFA)

What is Radiofrequency Ablation (RFA)?

The greatest modern advancement in treating varicose veins is an innovative, minimally invasive procedure called radiofrequency ablation. The goal of the procedure is to restore healthy circulation throughout your leg. During RFA, heat is delivered to the affected vein wall, which will force it to close, stopping the backwards flow of blood through the vein, thus correcting the underlying cause of varicose veins. Once the procedure is complete, blood flow is diverted to healthy veins, restoring healthy circulation in the leg. This technique has replaced the much more invasive surgical vein stripping procedures, which required general anesthesia, several cuts on the leg, at least two nights in the hospital, and had a higher risk of infection.

What to expect during RFA treatment?

At Siragusa Vein and Laser, RFA is a quick in-and-out procedure that some patients even have done during their lunch break.  Local anesthesia is administered to ensure your comfort throughout the entire 10-minute procedure.  We also offer ProNox, which is a blend of Nitrous oxide and oxygen to help relieve any anxiety you may have about procedures. During your RFA procedure, Dr. Siragusa will use an ultrasound to guide a thin catheter into the vein requiring treatment with no need for any incisions. The tiny catheter delivers a precise amount of radiofrequency energy to the inside of the vein. This energy heats up the wall of the vein, causing it to shrink and close. Once treated, blood flow is rerouted to nearby healthy veins, restoring healthy circulation and the sealed-off vein is slowly absorbed by your body.  At the conclusion of your procedure, our staff will help you to apply a compression stocking and answer any questions you may have before leaving the office and returning to your normal daily activity.

What to expect following treatment?

Patients will be instructed to wear a compression stocking following treatment for five to seven days, and will remove the compression stocking at night when they sleep.  The procedure is efficient, minimally invasive and requires minimal downtime. Although some patients may experience mild aching in the area, this is generally very well controlled with Ibuprofen and usually goes away within a few days. Patients who undergo RFA can usually resume regular activities immediately after treatment. However, it is best to avoid strenuous activity and extended standing during the first few days. 

At Siragusa Vein and Laser, most of our patients notice a significant improvement in the size of their varicose veins as well as an improvement in their symptoms within two days of their procedure.
