Long-term outcome after spinal cord infarctions

To investigate long-term outcome in patients with spontaneous spinal cord infarctions and secondly to compare outcome with that of patients with cerebral infarction.

The study includes 30 patients with spinal cord infarction discharged between 1995 and 2010. Surviving patients were contacted by telephone and sent a questionnaire. Data on employment, function, depression, fatigue, pain, and quality of life were obtained and compared to similar data obtained from a group of patients with cerebral infarction.

Seven patients with spinal cord infarction had died after a mean follow-up of 7.1 years. Mortality was associated with poor functioning in the acute phase. Thirteen of 20 responding patients were able to walk. Compared to patients with cerebral infarction, patients with spinal cord infarction had significantly lower mortality, poorer functioning, higher re-employment rate, and more pain.

Many patients with spinal cord infarction experience significant improvement. Even though functional outcome is worse, the mortality rate is lower and the frequency of re-employment higher among patients with spinal cord infarction compared to patients with cerebral infarction.
