Radiofrequency Ablation (RFA)

Here’s how the RFA procedure is typically performed:

1. Preparation: The patient is positioned on an examination table, and vital signs such as blood pressure, heart rate, and oxygen levels may be monitored throughout the procedure. The area where the procedure will be performed is cleaned and sterilized.

2. Anesthesia: A local anesthetic is administered to numb the skin and tissues around the targeted area. In some cases, sedation may also be provided to help the patient relax during the procedure.

3. Imaging Guidance: Using fluoroscopy (live X-ray imaging) or ultrasound, the healthcare provider locates the target nerves responsible for transmitting pain. This helps ensure accurate placement of the RFA probe or electrode.

4. Probe Placement: Once the target nerves are identified, a special probe or electrode is inserted through the skin and positioned near the nerves. The placement of the probe is confirmed using imaging guidance.

5. Radiofrequency Ablation: Once the probe is correctly positioned, radiofrequency energy is delivered through the probe to create heat. This heat generates a lesion or small area of tissue destruction around the target nerves, effectively disrupting their ability to transmit pain signals.

6. Assessment: After the ablation is complete, the probe is removed, and the patient is monitored for a short period to evaluate the response. Some patients may experience immediate pain relief, while others may experience a gradual reduction in pain over the following days to weeks as the nerves are deactivated.
