Learn about the ClosureFast™ Radio Frequency Ablation (RFA) procedure.
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.
IMPORTANT: It is vital that patients keep their followup appointments. The reason for this is that vascular disease is not something that just goes away. It is a process that continues, even after any necessary procedures have been performed. Regular monitoring of your condition will be required in order to help you realize your best possible outcome for the long term.
