| Postdural puncture headache (PDPH) is a common complication of neuraxial anesthesia. It can occur after accidental dural puncture during epidural anesthesia, intentional dural puncture for spinal anesthesia, or other diagnostic or therapeutic procedures involving dural puncture. Clinically, PDPH presents as postural dull or pulsating headaches, often accompanied by auditory and (or) visual symptoms. It can also be associated with potential complications such as chronic headaches, back pain, cranial nerve dysfunction, subdural hematoma, and cerebral venous sinus thrombosis. This article reviews current researches on the pathophysiology, risk factors, prevention, and treatment of PDPH, aiming to provide a reference for clinical practice. |
