What is Radiofrequency Ablation (RFA)?
Radiofrequency ablation (RFA) is a minimally invasive procedure used to treat chronic pain by interrupting the transmission of pain signals from specific nerves to the brain. By precisely heating and ablating the targeted nerve tissue, an RFA can provide long-term relief for various types of chronic pain.
How is Radiofrequency Ablation (RFA) Performed?
To perform radiofrequency ablation:
- 1. The treatment area is numbed with a local anesthetic to minimize discomfort.
- 2. Using fluoroscopic (X-ray) guidance, the physician carefully inserts a thin needle through the numbed skin and tissue and directs it to the specific nerve or nerves causing the patient’s pain.
- 3. A small electrode is then passed through the needle and positioned next to the target nerve(s).
- 4. The electrode is then activated, delivering radiofrequency energy that creates a controlled lesion on the nerve, disrupting its ability to transmit pain signals.
- 5. This process may be repeated to treat multiple painful nerve branches, as needed.
What Supplies and Medications are Used for Radiofrequency Ablation (RFA)?
The key components for radiofrequency ablation include:
- – Local anesthetic (e.g. lidocaine) to numb the treatment area
- – Fluoroscopic imaging equipment to precisely guide needle and electrode placement
- – Radiofrequency generator and specialized electrode to deliver the thermal ablation
The physician selects the appropriate equipment and techniques based on the patient’s anatomy and the specific nerves being targeted.
What to Expect After Radiofrequency Ablation (RFA)?
After the procedure, the patient may experience some discomfort or soreness at the treatment site, which can typically be managed with over-the-counter pain medication.
Over the next several weeks, patients often report a gradual reduction in their chronic pain as the ablated nerves regenerate and the full effects of the procedure take hold. The pain relief provided by RFA can last for several months, though the duration may vary depending on the individual.
Patients should follow their physician’s instructions regarding any activity restrictions and schedule any necessary follow-up appointments. They should promptly report any concerning symptoms, such as increased pain or new neurological deficits, to their healthcare provider.
