title: [Postdural puncture headache].
abstract: PDPH are not the privilege of spinal anaesthesia, as they can occur in various circumstances including epidural anesthesia, surgical wound of the dura, spinal tap and/or myclography. Diagnosis PDPH can be discussed with four etiologies: cortical vein thrombosis, meningitis, intracranial haematomas (intracerebral, subdural) or migraine. PDPH result from the leakage of CSF via the dural hole, responsible of hypotension of CSF in the subarachnoid compartment. Several etiologies and predisposing factors are discussed. The incidence of PDPH varies with age, maximum from 15 to 50 years-old, the decreasing to reach a very low incidence over 65 PDPH seems to occur more frequently in women, especially during pregnancy. The diameter of the spinal needle is the main factor of PDPH. Using small diameters (25 G and less) allows to reduce the percentage of PDPH, as well as using specially designed needles with a "pinpoint bevel" (Sprîtte, Whitacre). When PDPH occur, no specific treatment is required before the fifth day, as they spontaneously resolve in 80% of the patients, without any intervention. After then, epidural blood patch allows 90% success rate. Other therapeutic proposals are discussed. Finally, prevention of PDPH appears to be the keypoint, paying particular attention to the choice of the needle and of the spinal puncture technique.
