A

B. hematoma has grown big and surgery is indicated

22
Q

What is the order of events in hemorrhagic stroke?

A

Vascular rupture -> Hematoma formation -> Hematoma expansion -> Edema formation

23
Q

What is the function of Hibernating penumbra?

A

Causes hypometabolism to conserve energy

24
Q

states that, in an incompressible cranium, the blood, CSF, and brain tissue exist in a state of volume equilibrium, such that any increase in volume of one of the cranial constituents must be compensated by a decrease in volume of another

A

Monro-Kellie hypothesis

25
