Stellate Ganglion

What is it?
The stellate ganglion is a consolidation of nerves in the lower part of your neck which gives the sympathetic nerve supply to the face, upper thorax, and arms on the stellate ganglion. There are two stellate ganlions, one on each side. In patients who have certain neuropathic or nerve-related conditions such as post-herpetic neuralgia (shingles) or reflex sympathetic dystrophy, etc., performing blockade (turning off) on the stellate ganglion will lead to a reduction in pain.

The injection
The injection is performed with the guidance of x-ray to provide proper placement of medication. Prior to receiving the injection intravenous medication will be delivered to provide you with some sedation throughout the procedure. The injection takes approximately 15 minutes.

After the injection
Following the injection you may notice hoarsness and nasal stuffiness on the side of the block. Your eyelid may droop, the pupil may get smaller, and the white part of the eye may become reddened. These effects will only last for a short period of time. Ice should be applied to the injection site to minimize any swelling or irritation from the injection. It is recommended that you follow up with your physician in 1 to 2 weeks following the injection.
