Key Points about Extradural Haematoma
- Definition: Extradural haematoma (EDH) is a collection of blood between the inner surface of the skull and the dura mater, usually caused by trauma, most commonly a fracture of the temporal bone leading to rupture of the middle meningeal artery.
- Causes: The most common cause is head trauma, typically following a skull fracture. Blunt force trauma is the typical mechanism of injury, especially in road traffic accidents or falls.
- Symptoms: Symptoms often include a “lucid interval” where the patient appears to recover after the initial trauma, followed by a rapid deterioration in consciousness, headache, nausea, vomiting, and focal neurological signs like pupil dilation.
- Diagnosis: CT scanning is the gold standard for diagnosis, showing a biconvex (lens-shaped) collection of blood on the affected side of the brain. Prompt imaging is critical to prevent irreversible damage.
- Management: Immediate neurosurgical intervention is required, often involving craniotomy or burr hole evacuation of the haematoma. Stabilisation of the patient and monitoring of intracranial pressure are crucial.
- Complications: Without rapid treatment, EDH can lead to brain herniation, permanent neurological deficits, or death due to increased intracranial pressure.
