title: A case of Horner's syndrome following lateral sagittal infraclavicular block.
abstract: Horner's Syndrome results from paralysis of the ipsilateral sympathetic cervical chain (stellate ganglion) caused by surgery, drugs (mainly high concentrations of local anesthetics), local compression (hematoma or tumor), or inadequate perioperative positioning of the patient. It occurs in 100 % of the patients with an interscalene block of the brachial plexus and can also occur in patients with other types of supraclavicular blocks. Horner's syndrome may be described as an unpleasant side effect because it has no clinical consequences in itself. For this reason anesthesiologists should be aware of this syndrome and if it occurs patients should be reassured and monitored closely. In this case report, we presented a case of Horner's Syndrome following lateral sagittal infraclavicular block (LSIB), a newly described technique.
