Cerebral Venous Thrombosis After a Possible Inadvertent Dural Puncture for Labor Epidural Analgesia

Pregnancy is a hypercoagulable state that increases the risk of thrombotic complications. A 32-year-old gravida 4 para 3 (G4P3) had a dural puncture during epidural catheter placement for labor analgesia. A positional headache started after delivery and continued for several days. A week after the delivery, she developed non-positional headaches along with seizures. Magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) lead to the diagnosis of cerebral venous thrombosis (CVT). A factor V Leiden mutation was also found; that was suspected to contribute to the development of CVT along with dural puncture and pregnancy. CVT can present with non-positional headaches a week after the dural puncture.
