Study Notes
Intracranial Haemorrhages
- Intracranial haemorrhage is bleeding within the cranial cavity, caused by ruptures or tears of blood vessels (meningeal vessels, dural veins, cerebral arteries).
- This is a serious medical emergency, as the blood buildup increases intracranial pressure (ICP).
- Increased ICP can compress delicate brain tissue, restrict blood supply, and lead to brain herniation (parts of the brain being squeezed past structures in the skull).
- Trauma is the most common cause.
Classifications of Intracranial Haemorrhages
-
Extra-axial (outside brain tissue) haemorrhages:
- Epidural haemorrhage
- Subdural haemorrhage (acute and chronic)
- Subarachnoid haemorrhage
-
Intra-axial (inside brain tissue) haemorrhages:
- Intracerebral haemorrhage
- Intraventricular haemorrhage
Epidural Haemorrhage
- Cause: Primarily due to motor vehicle accidents (MVAs), falls, assaults, or direct blunt trauma (temporal bone fractures).
- Location: Bleeding in the epidural space (between the skull and dura mater).
- Blood vessel: Middle meningeal artery.
- Speed of bleeding: Rapid (arterial).
-
Clinical features:
- Brief loss of consciousness (LOC) followed by a short "lucid interval."
- Rapid mental status deterioration as ICP rises.
- Worsening headache.
- Hemiparesis (weakness on one side of the body).
- Seizures.
- Fixed/dilated pupils.
- Coma and death if untreated
- CT scan: Biconvex lens-shaped hyperdense area. It doesn't cross the midline.
- Management: Usually requires surgical evacuation of the bleed.
Acute Subdural Haemorrhage
- Cause: Often associated with MVAs, falls, or assaults involving acceleration/deceleration or rotational injuries. Skull fractures also possible.
- Location: Bleeding in the subdural space (between the dura mater and arachnoid mater).
- Blood vessel: Dural and bridging veins.
- Speed of bleeding: Slower (venous).
-
Clinical features:
- Brief LOC, followed by a longer "lucid interval"
- Possible coma, and death if untreated
- Decerebrate rigidity possible
- May present with coma at A&E
- CT scan: Crescent-shaped hyperdense area. Usually doesn't cross the midline
- Management: Usually requires surgical evacuation of the bleed.
Chronic Subdural Haemorrhage
- Cause: Falls or minor injuries, especially in elderly people (>60). Shrinking brain (atrophy) can tear bridging veins.
- Location: Subdural space.
- Blood vessel: Bridging dural veins.
- Speed of bleeding: Slow (venous).
-
Clinical features:
- Gradual onset of neurological symptoms like headaches, personality changes, fluctuating drowsiness etc.
- CT scan: Crescent-shaped hyperdense area, does not cross midline.
- Management: Usually requires surgical evacuation of the bleed.
Subarachnoid Haemorrhage
- Cause: Blunt trauma, acceleration/deceleration injuries, penetrating injuries, or a ruptured congenital aneurysm
- Location: Subarachnoid space, around the circle of Willis.
- Blood vessel: Cerebral arteries.
- Speed of bleeding: Fast (arterial).
-
Clinical features:
- Sudden severe headache
- Vomiting
- Seizures
- Deteriorating mental status
- Meningism signs (e.g., stiff neck, photophobia)
- CT scan: Focal hyperdense area in sulci
- Management: No surgical option (External ventricular drain to reduce ICP). Treat increased ICP and reduce secondary brain injury.
