title: Shunting for syringomyelia in patients with spinal cord injuries: self-reported, long-term effects in 8 patients.
abstract: OBJECTIVE
  To investigate the long-term effects of shunting on neurologic outcome of syringomyelia, a complication of spinal cord injury (SCI).
  
  
  METHODS
  Retrospective data collection using telephonic survey.
  
  
  METHODS
  University based medical center.
  
  
  METHODS
  Eight of 15 patients who had shunts placed between 1976 and 1999.
  
  
  METHODS
  Review of clinical records and self-reported telephone interview.
  
  
  METHODS
  Initial clinical presentation, recovery after shunt placement, and subsequent neurologic status were recorded. Patients were asked to rate symptomatic improvement after surgery on a 100-point analog scale; they were also asked whether they would have the surgery again.
  
  
  RESULTS
  Presenting symptoms were weakness in all 8 patients, pain in 5 patients, and numbness in 5 patients. After shunting, 6 patients had improved strength, all had less pain, and 2 had less numbness. Six patients experienced neurologic decline an average of 2 years after shunt placement, 3 because of shunt failure, 2 from a new syrinx, and 1 from both shunt failure and new syrinx. Two of the 3 patients who underwent second shunt placements for a new syrinx had full neurologic recovery. Six patients said they would repeat the shunting procedure if necessary, 1 was uncertain, and 1 would not.
  
  
  CONCLUSIONS
  Initial improvements noted after shunting provide long-lasting effects, even though many patients may need a second procedure. Less pain and improved strength are more significant than decreased numbness.
