Sub-dural hematoma following spinal anesthesia treated with epidural blood patch and burr-hole evacuation: a case report.

The appearance of a subdural hematoma (SDH) following spinal anesthesia is a serious and rare complication which mandates prompt diagnosis, although the treatment modalities are not well codified. Patients with post-dural puncture headache (PDPH) non-responsive to conservative measures and/or those patients with a change of the character of the headache should be considered seriously. In symptomatic patients, evacuation of SDH is essential but epidural blood patch should be strongly considered as it can prevent reappearance of SDH by sealing the dural defect.
