Zorluk: KolayNeurosurgery

A 24-year-old man is brought to the emergency department 3 hours after a skateboarding accident in which he struck the right side of his head against a curb. Witnesses report he lost consciousness for approximately 1 minute at the scene, but then awoke, appeared completely normal, and walked home. Over the past hour, he has developed a severe headache, nausea, and progressive lethargy. His temperature is 37.0°C (98.6°F), blood pressure is 165/90 mm Hg, pulse is 52/min, and respirations are 12/min. Glasgow Coma Scale score is 10 (E2, V3, M5). Neurologic examination reveals a dilated and sluggishly reactive right pupil. Non-contrast CT of the head reveals a hyperdense, biconvex fluid collection between the skull and the dura mater over the right cerebral convexity. Which of the following is the most appropriate next step in management?

  1. Emergent craniotomy and hematoma evacuationCevap
  2. B
    Observation in the intensive care unit with serial neurologic examinations
  3. C
    Magnetic resonance imaging of the brain
  4. D
    Lumbar puncture to measure cerebrospinal fluid opening pressure
  5. E
    Administration of intravenous broad-spectrum antibiotics

Cevap

Emergent craniotomy and hematoma evacuation
The patient's clinical presentation (head trauma, lucid interval, rapid neurologic decline, Cushing reflex) and CT findings (hyperdense biconvex shape) are classic for an acute epidural hematoma. The ipsilateral dilated pupil indicates uncal herniation due to a rapidly expanding intracranial volume. The definitive and life-saving treatment for a symptomatic epidural hematoma causing mass effect is an emergent craniotomy and surgical evacuation of the blood clot.

Adım Adım Çözüm

1
Analyze the clinical history and physical examination findings.
The patient experienced head trauma followed by a classic 'lucid interval' and subsequent rapid neurologic decline. Vitals show hypertension and bradycardia (Cushing reflex), and he has an ipsilateral dilated pupil.
These findings are highly suspicious for an expanding intracranial mass causing elevated intracranial pressure and uncal herniation.
2
Interpret the provided imaging results.
The non-contrast CT shows a hyperdense, biconvex (lens-shaped) collection.
This specific imaging pattern definitively diagnoses an acute epidural hematoma, typically caused by rupture of the middle meningeal artery.
3
Determine the most appropriate management for the diagnosed condition.
Immediate surgical intervention is required.
An epidural hematoma causing neurologic compromise and signs of herniation is a surgical emergency requiring emergent craniotomy for evacuation of the clot and source control of the bleeding.
