Vasogenic Edema Flashcards
1
Q
What is cerebral edema?
A
Increased fluid content in brain tissue.
2
Q
What results in cerebral edema?
A
Increased extra/intracellular tissue volume.
3
Q
Three types of cerebral edema?
A
Vasogenic, cytotoxic (metabolic), and interstitial.
4
Q
- What is clinically the most important type of cerebral edema?
A
Vasogenic.
5
Q
- Where does vasogenic edema start?
A
In the area of injury, then spreads.
6
Q
- Where does fluid accumulate in vasogenic edema?
A
In the white matter of the ipsilateral side because the parallel myelinated fibers separate more easily.
7
Q
Why does edema promote more edema?
A
Because of ischemia from the increasing pressure.
8
Q
- What does vasogenic edema do?
A
Increases permeability of capillary endothelium of the brain after injury to a vascular structure.
