| Abstract |
|
A stellate ganglion block (SGB) is a widely used procedure in the treatment of chronic pain syndromes in the facial and cervicobrachial regions as well as in nonpainful conditions.
The complications of a stellate ganglion block include intra-arterial or intracranial injection of local anesthetic, Horner's syndrome, phrenic nerve block, recurrent laryngeal nerve paralysis, brachial plexus block, and pneumothorax. Horner's syndrome after the performance of a stellate ganglion block is a valuable sign of a successful block, but contralateral or bilateral Horner's syndrome remains an unusual and poorly explained phenomenon.
We experienced a case of a 56 year-old female patient who had developed ipsilateral and contralateral Horner's syndrome after a stellate ganglion block. The ipsilateral Horner's syndrome was resolved after several hours but the contralateral side lasted for a week. |
