2. ‫المفهوم العلمي لموت الدماغ‬

3. Intracranial compensation

4. Concepts of Brain Injury
• Primary injury: area of maximum
neuronal damage
• Penumbra: area of less injured
and potentially recoverable
neuronal tissue
• Secondary injury: follows
primary injury and causes further
neuronal damage

5. Primary Brain Injury
• Trauma: concussion,
contusion, shear injury
• Ischemia: global, regional
• Inflammation
• Compression: tumor, edema,
hematoma
• Metabolic insults

6. Secondary Brain Injury
• Hypoperfusion: high intracranial
pressure, edema, vasospasm
• Hypoxia: hypoxemia,
hypoperfusion, high O2
consumption
• Harmful mediators: reperfusion,
inflammation
• Electrolyte or acid-base changes

7. Intracranial pressure volume

8. Elevated ICP head CT

10. Pathological A waves (also called
plateau waves)
• are abrupt, marked elevations
in ICP of 50 to 100 mmHg
• which usually last for minutes
to hours.
• The presence of A waves
signifies a loss of intracranial
compliance
• heralds imminent
decompensation of
autoregulatory mechanisms
• the presence of A waves
should suggest the need for
urgent intervention to help
control ICP.

24. Size is the most important
predictor for patient outcome
• A patient with a
haemorrhage the
size of a ping pong
38 ml
ball is likely to have
a better outcome
43 ml
than a patient with a
haemorrhage the
size of golf ball:
 mortality on ’ping
pong’ size: app. 40%
 mortality on ’golf ball’
size: app. 70%
