Abstract

Epidural blood patches (EBPs) are routinely used to treat symptoms (eg, headaches) associated with spontaneous intracranial hypotension. Although cerebrospinal fluid leakage commonly involves the periforaminal areas of the cervical or thoracic spine, EBPs have been historically performed at the lumbar level. Recent evidence suggests that targeting the causative spinal segment may provide greater clinical benefits. While previous reports have targeted foraminal leaks with segmental thoracic or cervical injections, we present a case report detailing the novel use of a navigable epidural catheter to perform a selective EBP at the C7/T1 foramen.
