The stellate ganglia may be cut in order to decrease the symptoms exhibited by Raynaud's phenomenon and hyperhydrosis (extreme sweating) of the hands. 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), and symptoms associated with alterations ...
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
The axillary block is particularly useful in providing anesthesia and postoperative analgesia for surgery to the elbow, forearm, wrist, and hand. The axillary block is also the safest of the four main approaches to the brachial plexus, as it does not risk paresis of the phrenic nerve, nor does it have the potential to cause pneumothorax. [12]
The cervical ganglion has three paravertebral ganglia: superior cervical ganglion (largest) – adjacent to C2 & C3; postganglionic axon projects to target: (heart, head, neck) via "hitchhiking" on the carotid arteries; middle cervical ganglion (smallest) – adjacent to C6; target: heart, neck; inferior cervical ganglion.

The indications for ganglion impar blockade are based on the anatomical location of pain and include various conditions such as perineal pain (with or without malignancy), rectal/anal pain (proctitis), distal urethral pain, vulvodynia, scrotal pain, female pelvic/vaginal pain (distal 1/3), sympathetically-maintained pain (e.g., Complex Regional ...
