title: The relationship between brain surface elastance and brain reexpansion after evacuation of chronic subdural hematoma.
abstract: BACKGROUND
  Brain stiffness has been thought to be a factor affecting brain re-expansion after the evacuation of chronic subdural hematoma.
  
  
  METHODS
  As an index of brain stiffness, the pressure for compressing the brain using an ophthalmodynamometer was defined as brain-surface elastance. This elastance in 14 patients was measured and analyzed in relation to brain re-expansion.
  
  
  RESULTS
  Patients with an enlarged subdural space on computed tomography 1 month after the operation had higher elastance. There was a correlation between high elastance and high age.
  
  
  CONCLUSIONS
  Measuring the elastance after evacuation of the hematoma may help predict the persistence of a subdural space.
