[An anesthetic experience of a patient with subacute myelo-optico-neuropathy for bilateral mastectomy].

A 79-year-old woman with subacute myelo-optico-neuropathy (SMON) underwent a bilateral mastectomy for breast cancer. She has been suffering from SMON for 32 years. Her preoperative neurological examination revealed cryesthesia and dyskinesia in the lower extremity, and numbness in the crues. Physical examination revealed respiratory dysfunction. A combination of general anesthesia and epidural block was employed to minimize the dose of anesthetics which may affect the neuronal symptoms. Intraoperative course was uneventful and continuous epidural block was effective for postoperative pain control. There was no neurological deterioration postoperatively.
