title: Successful use of epidural blood patch for postdural puncture headache following lumbar sympathetic block.
abstract: OBJECTIVE
  A 21-year-old man was scheduled for a diagnostic lumbar sympathetic block for reflex sympathetic dystrophy of the right lower extremity.
  
  
  METHODS
  The patient experienced paresthesias with possible puncture of a dural sleeve during needle placement under fluoroscopy. After discharge, the patient developed a positional headache, which increased in intensity over 48 hours. An epidural blood patch was subsequently performed.
  
  
  RESULTS
  The patient obtained complete relief from the headache.
  
  
  CONCLUSIONS
  Postdural puncture headache resulting from leakage of cerebrospinal fluid through a punctured dural sleeve may be successfully treated with an epidural blood patch should more conservative treatments fail.
