  "abstract": "Application for ESRA Abstract Prizes:Background and Aims Post-dural puncture headache (PDPH) is a significant complication after neuraxial anesthesia. The current gold standard treatment for PDPH is the epidural blood patch (EBP), which is highly effective but invasive and carries procedural risks. Therefore, less invasive regional techniques such as occipital nerve blocks (ONBs) and sphenopalatine ganglion blocks (SPGBs) have gained attention. This case series aims to compare the short-term effectiveness of ONBs and SPGBs in PDPH management.Methods Seven female patients aged 27–41 developed PDPH following spinal anesthesia. All patients underwent neurological examination and received conservative treatments including hydration, caffeine, NSAIDs, and bed rest. Four patients received bilateral ONBs (greater and lesser occipital nerves together) and three patients received bilateral transnasal SPGBs. All procedures utilized a combination of 15 mg bupivacaine%0,5 and 20 mg methylprednisolone. Pain intensity was assessed using a visual analog scale (VAS) in both supine and upright positions at 0, 5th minute, 20th minute, 6th hour, 24th hour and 5th day. Patients were followed regarding recurrence and adverse effects.Results All patients experienced rapid VAS reduction post-procedure. ONBs provided sustained pain relief with no recurrence in all four cases. SPGBs also resulted in prompt pain relief, but one patient reported recurrence of neck pain and was lost to follow-up. The median initial VAS was 9/10, which dropped to ≤2/10. No adverse events were reported.Conclusions Both ONBs and SPGBs appear to be effective interventions for PDPH when conservative treatments fail. Our results support the need for larger comparative studies to determine long-term efficacy and optimal patient selection.",
