Post-dural puncture headache (PDPH) is a common iatrogenic and incapacitating complication. Dural puncture can be intentional (spinal block, myelography,...) or accidental (epidural block). ⋯ Many options have been proposed, but only the epidural blood patch has apparent benefits. A few measures have been suggested to prevent PDPH after unintentional dural puncture, but none has been shown to work with certainty.
