Post-dural-puncture headache: Characteristics, management, and prevention

Post-dural-puncture headache is a common complication after both diagnostic and therapeutic procedures. Prompt recognition of the clinical syndrome, followed by supportive and corrective actions, can decrease the morbidity in those afflicted. The most useful preventive measure during dural puncture in adult patients is the use of smaller cannulae with the bevel aimed parallel to the long axis of the spine.
