Post-dural-puncture headache
Post-dural-puncture headache (PDPH) is a complication that can occur after a dural puncture, usually as a result of a diagnostic lumbar puncture or epidural anesthesia.
Pronunciation
Post-dural-puncture headache: /poʊstˈdʊrəlˈpʌŋktʃər ˈhɛdeɪk/
Etymology
The term "post-dural-puncture headache" is derived from the Latin post meaning "after", dura mater referring to the outermost layer of the meninges, punctura meaning "puncture", and the Old English heafod ece meaning "headache".
Definition
A post-dural-puncture headache is a severe and debilitating headache that occurs after a hole is made in the dura mater during a lumbar puncture or epidural anesthesia. The headache is caused by leakage of cerebrospinal fluid (CSF) through the hole, leading to a decrease in CSF pressure.
Symptoms
The primary symptom of a post-dural-puncture headache is a severe, persistent headache that worsens when the patient is upright and improves when the patient is lying down. Other symptoms may include neck stiffness, tinnitus, photophobia, and nausea.
Treatment
Treatment for a post-dural-puncture headache typically involves conservative measures such as bed rest, hydration, and analgesics. If these measures are not effective, an epidural blood patch may be performed.
