[Post-dural puncture headache].

Post-dural puncture headache (PDPH) is a frequent complication to procedures involving dural puncture. The condition is caused by excessive leakage of cerebrospinal fluid through the puncture, and it is most often seen in young women. The risk can be significantly reduced by using smaller, atraumatic needles. PDPH is characterised by a dull headache, which worsens in postural position. Usually, PDPH is a self-limiting condition, which resolves within a week with conservative treatment, but it may become chronic. Treatment with epidural blood patch is effective both in acute and chronic stages of PDPH.
