Transnasal Sphenopalatine Ganglion Block for Postdural Puncture Headache in an Adolescent: A Case Report.

We present a pediatric patient with postdural puncture headache after a lumbar puncture, who was successfully treated with a sphenopalatine ganglion block. An uneventful autologous epidural blood patch had been placed 2 days before, but the patient reported a recurrence of symptoms after about 5 hours. Sphenopalatine ganglion block is well described in the treatment of postdural puncture headache for the obstetric population, but examples of its use in the pediatric population are not described. To our knowledge, this is the first pediatric case of sphenopalatine ganglion block for postdural puncture headache reported in the literature.
