|Nerve: Stellate ganglion|
|Plan of right sympathetic cord and splanchnic nerves. (Stellate ganglion not visible, but region is shown.)|
|Latin||ganglion cervicothoracicum, ganglion stellatum|
Injection of local anesthetics near the stellate ganglion can sometimes mitigate the symptoms of sympathetically mediated pain such as complex regional pain syndrome type I (reflex sympathetic dystrophy). Complications associated with a stellate ganglion block include Horner's syndrome, intra-arterial or intravenous injection, difficulty swallowing, vocal cord paralysis, epidural spread of local anaesthetic and pneumothorax.
Stellate ganglion is located at the level of C7 (7th cervical vertebrae), anterior to the transverse process of C7, posterior to the neck of the first rib, and just below the subclavian artery.
