Post-Dural Puncture Headache Diagnosis and Management

Primary Diagnosis: Post-Dural Puncture Headache

The American College of Radiology suggests that orbital and temporal headache after spinal anesthesia most likely indicates post-dural puncture headache (PDPH), which occurs in 2-8% of cases and typically develops within the first 5 days after the procedure 1, 2
The key diagnostic feature of PDPH is a postural (orthostatic) headache that worsens when upright and improves when lying down, as recommended by the American College of Radiology 1, 2

Onset of PDPH typically occurs within 5 days of spinal anesthesia, most commonly within the first 48-72 hours, according to the American College of Radiology 1, 2
PDPH often presents with a postural/orthostatic pattern, worsening when upright and improving when supine, as noted by the American College of Radiology 1, 2
PDPH may be accompanied by neck stiffness and/or auditory symptoms, as reported by the American College of Radiology 1, 2

More than 85% of PDPH cases resolve spontaneously without treatment, according to the American College of Radiology 1, 2
Most PDPH cases resolve within 2 weeks, though severity varies, as noted by the American College of Radiology 1, 2

Conservative management is appropriate initially for typical PDPH, including maintaining adequate oral hydration, multimodal analgesia with acetaminophen and NSAIDs, and caffeine up to 900 mg/day, as recommended by the American College of Radiology 1, 2
Epidural blood patch (EBP) is the definitive treatment for severe or non-resolving PDPH, with over 85% success rate, according to the American College of Radiology 1, 4, 2
EBP should be performed at the level of the original dural puncture, with marked pain reduction occurring within 4 hours of the procedure, as noted by the American College of Radiology 2

Brain imaging (MRI head with and without contrast preferred) is mandatory when headache onset occurs more than 5 days after spinal anesthesia, or when there is a non-orthostatic headache or loss of postural character, as recommended by the American College of Radiology 5, 6, 2
Imaging is also indicated when there are new neurological symptoms or when the headache location changes from typical occipital to frontal/orbital/retroorbital, according to the American College of Radiology 7

Rebound headache may occur after epidural blood patch treatment, presenting with reversal of orthostatic symptoms, headache location shift, nausea, vomiting, and blurry vision, as reported by the American College of Radiology 7
Rebound headache is usually self-limited and managed conservatively, with acetazolamide prescribed to lower CSF production, according to the American College of Radiology 7
