Intercostal Nerve Pulsed Radiofrequency

Pulsed radiofrequency (PRF) of an intercostal nerve is a treatment option for persistent, localised chest-wall or upper abdominal pain when the intercostal nerve is thought to be an important pain generator. It may be considered when conservative treatment and diagnostic nerve blocks have not provided sufficiently lasting relief.

Under image guidance, a specialised needle is positioned close to the affected intercostal nerve. After careful testing of the position, short bursts of radiofrequency energy are delivered around the nerve. Unlike thermal radiofrequency ablation, PRF uses controlled pulses rather than creating a sustained high-temperature lesion, with the aim of modulating pain signalling while preserving normal nerve function.

The benefit from PRF varies between individuals and may develop over days or weeks rather than immediately. Some patients obtain relief for several months or longer, while others have a more limited response. Dr Danesh will consider the response to any preceding nerve block, the cause of the pain and your overall treatment plan when deciding whether PRF is appropriate.
