Reevaluating optic nerve sheath diameter in predicting postdural puncture headache: exploring clinical implications beyond threshold values

Abstract

The study by Boyaci et al. assessed using optic nerve sheath diameter (ONSD) ultrasound to predict postdural puncture headache (PDPH) in spinal anesthesia patients. In their single-center study of 83 patients, PDPH incidence was high at 22.9%, partly due to the use of a traumatic needle. Most PDPH cases had mild pain (84.3%) and required treatment without a blood patch. No effective PDPH prevention exists, questioning the clinical value of early diagnosis via ultrasound. ONSD's relationship with intracranial pressure (ICP) is acknowledged, but a definitive ONSD cutoff for PDPH is lacking. Other studies suggest ONSD changes may be linked to treatment outcomes in related conditions, emphasizing the importance of investigating risks of epidural blood patch failure.
