Q

Most common location for htnsive intracerebral hemorrhage

17
Q

Pons hemorrhagic stroke sx

A

Deep coma, total paralysis, decerebrate rigidity, death

18
Q

What is affected in sensorimotor lacunar stroke

A

Junction of internal capsule and thalamus

19
Q

What CN is commonly affected in SAH

20
Q

How big do aneurysms get before they’re at risk of rupture

21
Q

What CN is affected in cerebellar hemorrhagic stroke

22
Q

What is hunt and hess scale

A

Scale for severity of nontraumatic SAH (1-5)

23
Q

What is affected in hemichorea-hemiballismus

A

Lacunar stroke of head of caudate, thalamus, subthalamic nucleus

24
Q

Large vs small AVM and risk of hemorrhage

A

More common in small AVM because of increased resistance and pressure. Large AVM has low pressure and needs a distal blood clot to increase pressure to cause hemorrhage

25
Signs of CN3 problem
Deviation of eye to lateral side because of unopposed LR muscle. Ptosis. Mydriasis. Paralysis of accommodation.
26
What is affected in pure sensory stroke
Lacunar - thalamus
27
What is used to treat vasospasm after SAH
Nimodipine (CCB)
