A refractory head tremor appearing after volatile anesthesia combined with epidural anesthesia in a patient with spinocerebellar ataxia type 6

摘要

Abstract A 64-year-old female patient with spinocerebellar ataxia type 6 was referred to our department for pancreatic cancer and anesthetized with volatile anesthesia combined with epidural anesthesia for pancreaticoduodenectomy. No complications arose during surgery. On postoperative day 4, a head tremor was noticed at the time of mobilization. The tremor was a postural and “no-no” tremor rather than an intention or resting tremor. The head tremor caused difficulty in eating and in other activities of daily living. No abnormal results were obtained by magnetic resonance imaging of the brain. The tremor was resistant to drugs, including anti-Parkinson drugs and benzodiazepines, and was therefore difficult to treat.
