Vgontzas A, et al. - Researchers sought to describe acute headache diagnoses in women presenting emergently in the postpartum period. In addition, they searched for the factors that could be associated with secondary vs primary headache. They identified secondary headache in nearly three-quarters of postpartum women who present with acute onset headache and were receiving neurological consultation. Secondary headache most commonly featured postdural puncture headache (PDPH), postpartum preeclampsia (PEC), and a diverse group of cerebrovascular headache disorders (21.7%). In the absence of a headache history and a clear PDPH description, they recommend strong consideration for neuroimaging to rule out cerebrovascular etiologies of headache as well as close monitoring for signs and symptoms of preeclampsia in women presenting with acute severe postpartum headache.
