Review Case Reports
Case report: epidural blood patch in the treatment of abducens palsy after a dural puncture.
To describe a case of iatrogenically induced abducens nerve palsy following a diagnostic lumbar puncture, and to review the evidence for blood patching in the management of sixth cranial nerve palsy after dural puncture. ⋯ Experience from this case as well as other case report evidence suggest that an epidural blood patch performed more than 24 hr after the onset of a sixth cranial nerve palsy consistently fails to relieve diplopia. An epidural blood patch executed within 24 hr from the onset of diplopia could possibly lead to partial improvement and/or earlier resolution of symptoms.
