title: Postdural puncture headache is a risk factor for new postdural puncture headache.
abstract: The aim of this study was to determine if patients with a previous history of postdural puncture headache (PDPH) might be prone to a new episode after spinal anaesthesia. Consecutive patients (n = 258) who had had surgery under spinal anaesthesia were studied. Of 42 patients with a previous history of PDPH, eight (19.0%) developed a new PDPH episode; whereas out of 216 without a previous history of PDPH, only 15 (6.9%) presented with PDPH. Previous PDPH history indicates a higher chance of a new episode of PDPH after spinal anaesthesia. Women are more susceptible to such recurrences.
