Radiofrequency Ablation Therapy

RFA treatment is an outpatient procedure we regularly perform at Allegheny Vein and Vascular and usually takes just under half an hour. The entire treatment — from arrival to preparation through treatment — may take up to 2 hours.

To ensure patient safety, at AVV we perform RFA as a sterile procedure. After mapping the malfunctioning vein and applying a numbing medication to the small access point, Dr. Tahara uses ultrasound guidance to access the vein. An RFA catheter is then inserted into the vein and the tip is carefully positioned using ultrasound imaging to maximize treatment efficacy while minimizing potential complications. Tumescent anesthetic (a saline solution containing numbing medication) is injected around the vein. This not only provides comfort but also creates a protective barrier around the vein, preventing transmission of heat energy to the surrounding tissue. As the catheter is activated and the tip heats up, it is drawn back, heat sealing the length of the vein segment by segment until complete treatment of the vein is achieved. The catheter is then removed. At AVV, total treatment time from access to removal of the catheter is usually less than 30 minutes. Patients often comment that the prep time takes longer than the procedure itself!

At the conclusion of treatment, pressure is then applied to the access site to control bleeding (typically minimal) Compression stockings and ace wrap bandages are used on the leg until the follow up ultrasound is performed within 24-72 hours.

Dr. Tahara will provide you with detailed instructions about how to prepare for the procedure during your initial evaluation. Dr. Tahara also explores your medical history during pre-op evaluation, including inquiries about recent illnesses, existing medical conditions, and any allergies you have or medications you’re taking. He will carefully explain how you should manage your regular medications, food, and drink just prior to the procedure. As a typical example, you may be told not to eat or drink anything several hours before arrival. You may also be asked to wear loose and comfortable clothing and refrain from wearing jewelry.
