Cranial subarachnoid hemorrhage as an unusual complication of epidural blood patch

Epidural blood patch (EBP) is an effective procedure for the reatment of spontaneous or iatrogenic dural tears. Reported comlications of EBP include lumbar and neck pain, paresthesia, loss f strength in the legs, temporary bradycardia, dizziness, cranial erve paralysis, and pneumocephalus [1–3]. We report a case of 36-year-old woman who developed a headache, persistent nauea, and vomiting because of subarachnoid hemorrhage (SAH) that ccurred after EBP. We suggest that EBP can result in SAH even if nadvertent puncture is avoided.
