title: Chiari I malformation in parturients.
abstract: OBJECTIVE
  To assess complications of regional as well as general anesthesia in parturients with Chiari I malformation.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  Academic medical center.
  
  
  METHODS
  All parturients in our institution who had the diagnosis of Chiari I malformation and delivered in our hospitals over a 50-year period.
  
  
  RESULTS
  12 parturients delivered 30 babies. Three deliveries were facilitated with general anesthesia. Nine deliveries were facilitated with central axis anesthesia, six with epidural anesthesia, two with a single injection of a spinal anesthetic, and one with a continuous spinal catheter. The patient who received a continuous spinal catheter developed a postdural puncture headache that resolved with an epidural blood patch. None of the patients who received general, spinal, or epidural anesthesia for their deliveries developed symptoms or had exacerbation of preexisting symptoms of Chiari I malformation.
  
  
  CONCLUSIONS
  General anesthesia, as well as spinal and epidural anesthesia, appeared to be safe and effective in our series of vaginal or cesarean delivery patients. The small number of patients in our series does not negate the cautious recommendations of others, but suggests that general anesthesia, as well as spinal or epidural anesthesia, can be used safely and effectively in these patients.
