Shy-Drager syndrome (SDS) is a chronic progressive disease with central autonomic nervous system defect, Parkinsonism, and cerebellar defect. The clinical maifestations of this syndrome are orthostatic hypotension, urinary and bowel dysfunction, impaired sexual potency, impaired libido, decreased sweating, ataxia, dysarthria, intension tremor, and vocal cord palsy. Anesthesiologists should consider SDS as having major implications during surgery when choosing the anesthetic technique, monitoring, and postoperative care because it causes loss of autonomic regulation of vascular tone. We report a successful spinal anesthesia for left salphingo-oophorectomy in a female patient with Shy-Drager syndrome.
