Radio frequency Ablation

Radiofrequency Ablation is a procedure which creates a nerve lesion produced by localized heat. When the lesion is placed over a painful nerve, pain signals are interrupted and pain perception by the brain is decreased. The procedure is performed in an outpatient setting. The treatment is done with local anesthesia along with IV sedation when needed. Before the procedure begins your physician starts by cleaning the skin over the injection site and injecting a local anesthetic to numb your skin. Another needle is placed through the numb tissue and the entire procedure is performed using fluoroscopic (X-ray) guidance. When the needle is in the correct location, an electrode is introduced into the center of the needle. Stimulation is initiated first with sensory stimulation and then with motor stimulation. When the correct needle position is verified, local anesthetic and sometimes a steroid medication are injected.

Radiofrequency thermo-coagulation – The electrode is heated to 50-80°C and kept at that temperature for several minutes. Electro-thermal heat is generated, which allows for destruction of surrounding pain fibers, thereby decreasing your pain.

Pulsed Radiofrequency – This technique is similar to thermo-coagulation RFA, but differs by a lower level of heat produced. This does not destroy the nerve tissue, but instead stuns the nerve. This method is less uncomfortable and in general only a mild pulsating sensation is felt.

After a brief recovery period, you are able to go home after the procedure. You may have some discomfort when the local anesthetic wears off.
