Sphenopalatine ganglion block by transnasal approach in post-dural puncture headache

Post-dural puncture headache (PDPH) is a common complication in neuraxial anesthesia, particularly epidural anesthesia, possibly related with loss of cerebrospinal fluid through the puncture site, exceeding its production rate [1]. Common PDPH symptoms include severe frontal and occipital headache, nausea, vomiting, hearing and visual disturbances, and dizziness [2]. Epidural blood patch is the standard therapy for PDPH, with efficacy rates ranging from 61 to 98% [1]. However, this is an invasive technique susceptible to risks, such as accidental additional dural puncture, bleeding, infection, and neurological complications [3].
