Endovenous Radiofrequency Ablation
Endovenous Radiofrequency Ablation (RFA) is a technique used for correcting venous reflux. Radiofrequency energy or Laser energy is delivered to the vein while the catheter is slowly withdrawn from the leg. This causes the vein to close and blood is re-routed to healthy veins.
After the procedure is complete, a small bandage is placed over the insertion site and a compression dressing is placed over the treated area. Walking is encouraged immediately after the procedure and patients can return to work the next day.
The endovenous ablation procedure with either Laser or Radiofrequency has proven to be highly effective for the treatment of venous reflux with a reported 95-97% success rate at patient's 12-month follow-up appointment.
Procedure Overview
What to Expect Before Treatment Begins
If necessary, you will be given Valium or a similar medication to help you relax during the treatment. The leg will be mapped using ultrasound. This shows the path of the diseased vein. Your leg will be prepped and draped for the procedure.
What to Expect During Treatment
Local anesthesia will be delivered to numb the treatment area. Using ultrasound guidance, the catheter will be inserted into the vein to be treated. The laser fiber is then inserted into the catheter and advanced to the upper end of the vein. Local anesthesia will be injected to numb the length of the vein. The fiber is then slowly withdrawn out of the vein, closing it as it is withdrawn.
What to Expect After Treatment
The patient is required to wear a compression dressing on treated leg for 2-3 days. Compression stockings should be worn for 2 weeks proceeding the operation. The patient can return to work the next day, however, abstain from high impact activities (running, step aerobics, etc.) for period of 3 weeks. Walking is encouraged and will aid in the healing process.
Possible side effects
Slight redness to skin in treated area may be present but will fade away within a few weeks. Patients may also experience slight swelling in treated area along with slight bruising
