Caudal epidural blood patch for treating intractable vomiting in a child after placement of a permanent intrathecal catheter.

Postdural puncture cerebral spinal fluid (CSF) leak most often manifests as a postdural puncture headache (PDPH). The reported frequency in young children varies (1-4). Persistent CSF leak may also be present without PDPH. We present a case of postoperative nausea and vomiting resulting from a presumed lumbar CSF leak in a nonverbal child after surgical placement of a permanent intrathecal catheter. Treatment with an epidural blood patch (EBP) via the caudal approach resulted in complete relief of symptoms.
