Flashcards in CNS Macro Trauma Deck (27):
1

What are parenchymal cells?

functional tissue as opposed to supporting structures

2

Prognosis for straight skull fracture

usually pretty good

3

If someone fractures their frontal bone, were they unconscious before or after the fall?

before, otherwise they would have caught themselves

4

If someone fractures their occipital bone, were they unconscious before or after the fall?

after

5

Depressed skull fracture main danger

may damage underlying brain tissue

6

Complicated fracture often found in depressed skull fractures where a chunk of bone breaks off from the skull

comminuted

7

This type of fracture is across a skull suture

diastatic

8

What is the complication related to a diastatic skull fracture

the suture widens

9

What type of skull fracture may result in CSF draining from the nose?

basal skull fracture

10

This type of skull fracture may result in a distant hematoma

basal skull fracture

11

What is a concussion?

an altered state of consciousness from a head injury due to change in momentum of the head--due to stretching and snapping of the brain and not brain pushing on skull

12

What is second impact syndrome?

having another concussion before the first one is healed

13

Complication of second impact syndrome?

rapid brain swelling

14

Pathophys of chronic traumatic encephalopathy

progressive degenerative disease of the brain caused by repetitive brain trauma

15

What protein is most associated with chronic traumatic encephalopathy?

tau protein

16

What are the two types of injury types of parenchymal tissue?

coup (same side as impact)
contrecoup (opposite side of impact)

17

"Shaken baby syndrome" is a type of this parenchymal injury

diffuse axonal injury

18

Diffuse axonal injury is due to what physiologically?

twisting/sheering of axons

19

Epidural hematomas are caused by damage to what vessel?

middle meningeal artery

20

What is the typical case of an epidural hematoma?

baseball to the head

21

Radiological finding of epidural hematoma?

smooth contours--dura is very hard so keeps blood contained

22

What vessels are damaged in a subdural hematoma?

cerebral veins (bridging)

23

What is the typical presentation of a subdural hematoma?

elderly patient falls but seems okay

24

Radiological findings of subdural hematoma

"ragged" edged

25

Pathophys of subarachnoid hemorrhage

berry aneurysm rupture, contusion

26

Typical presentation of subarachnoid hemorrhage

"worst headache I ever had"

27

What is the new-fangled treatment of berry aneurysms?

coils put in through femoral vein
