Postpartum headache is a common occurrence with various obstetric, neurologic, and anesthetic etiologies. Post dural puncture headache (PDPH) after neuraxial anesthesia is a culprit that may be less familiar to obstetricians. In this review, authors will discuss the differential diagnosis and management of postpartum headache, review PDPH, and explore evidence suggesting that PDPH may have greater implications than previously considered.
Emerging evidence suggests that PDPH, previously believed to be benign and self-limited, is associated with significant acute and chronic sequelae. A recent large database study links PDPH to subdural hematoma and cerebral venous sinus thrombosis. The authors also identified associations between PDPH and bacterial meningitis, depression, and back pain. A growing body of literature also links PDPH or unintentional dural puncture with an epidural needle (UDP) with development of chronic headaches.
Patients who experience UDP or PDPH should be counseled to return for evaluation for new or worsening headache. In the immediate postpartum setting, clinicians assessing these patients should have a low threshold to obtain brain imaging. In addition, obstetricians should be alerted that patients who suffer UDP may be prone to develop chronic headache disorders and consider referral to pain specialists.
