Radiofrequency Ablation (RFA)
RFA is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
Which Conditions Are Treated With Radiofrequency Ablation?
RFA can be used to help patients with chronic (long-lasting) low-back and neck pain and pain related to the degeneration of joints from arthritis.
How Long Does Pain Relief From Radiofrequency Ablation Last?
The degree of pain relief varies, depending on the cause and location of the pain. Pain relief from RFA can last from six to 12 months and in some cases, relief can last for years. More than 70% of patients treated with RFA experience pain relief.
What Happens During Radiofrequency Ablation?
You will meet with a doctor for an evaluation. If radiofrequency ablation is recommended, a doctor will explain the procedure in detail, including possible complications and side effects.
The doctor will also answer any questions you may have.
An intravenous (IV) line may be placed in a vein in your arm before the procedure and a local anesthetic and mild sedative may be used to reduce any discomfort during RFA. You may be awake during the process to aid in properly assessing the procedure. Ask your doctor about specifics beforehand.
After the local anesthesia (you will be awake but will not feel any pain) has been given, the doctor will insert a small needle into the general area where you are experiencing pain. Using X-ray, your doctor will guide the needle to the exact target area. A microelectrode is then inserted through the needle to begin the stimulation process.
During the procedure, your doctor will ask if you are able to feel a tingling sensation. The object of the stimulation process is to help the doctor determine if the electrode is in the optimal area for treatment.
Once the needle and electrode placement are verified, a small radiofrequency current is sent through the electrode into the surrounding tissue, causing the tissue to heat. You should not feel discomfort during the heating portion of the procedure.
