title: Failure of repeated blood patch in a parturient with spinal headache.
abstract: An obstetric patient, who received and accidental dural puncture, developed symptoms that persisted until the administration of a third epidural blood patch. Her management is presented. The possible causes of failure of this technique are discussed, with specific reference to the obstetric patient. The role of cerebrospinal fluid in the epidural space at the time of patching is considered.
