Lumbar Epidural Blood Patch via a Caudal Catheter After Surgical Dural Tear and Failed Repair: A Case Report.

We report a patient who developed a positional headache and pseudomeningocele after multiple lumbar surgeries for low back and radicular pain. An epidural blood patch via a lumbar approach was not feasible as a result of distorted lumbar anatomy after multiple back surgeries. An epidural blood patch was performed via catheter-threaded cephalad from a caudal approach. The patient had immediate relief after the procedure and at 1 year was still symptom-free. This combination technique may be considered as an alternative approach when a percutaneous lumbar epidural blood patch is disadvantageous.
