Stellate Ganglion Pulsed Radiofrequency Block

The stellate ganglion is a cluster of sympathetic nerve tissue in the neck that regulates blood flow and nerve activity to the head, neck and arm on that side, and can play a significant role in conditions such as complex regional pain syndrome (CRPS) affecting the arm. Targeting this ganglion can help calm an overactive sympathetic nervous system that is contributing to pain, swelling or temperature changes in the affected limb.

The procedure is performed under X-ray or ultrasound guidance, with local anaesthetic injected precisely around the stellate ganglion at the base of the neck, and pulsed radiofrequency may be applied to extend the duration of benefit for suitable patients. Careful, image-guided technique is essential given the ganglion's proximity to important structures in the neck.

For patients with sympathetically-mediated pain, this treatment can reduce pain and improve blood flow, swelling and temperature regulation in the affected arm or hand, often complementing physiotherapy and other elements of a broader CRPS management plan. Dr Danesh will discuss your individual response and whether repeat treatment is appropriate.
