Ischemic CVA Flashcards
(18 cards)
3 causes of Ischemic CVA
thrombotic (most common d/t plaque built up)
embolism (clot traveled)
systemic hypoperfusion (clots not involved but lack of blood=insufficient blood to brain)
The intake of cocaine vasoconstricts causing the stroke in which type of Ischemic CVA?
systemic hypoperfusion
give the two types of CVAs
ischemic and hemorrhagic
ischemic CVAs account for what percentage of CVAs?
80%
hemorrhagic bleeds account for what percentage of CVAs?
20%
give the patho for CVAs
lack of blood supply to the brain
in which ischemic CVA are clots not involved in?
systemic hypoperfusion
which CV is classified a very specialized and has specific S&S?
hemorrhagic CVA
what is the common cause of intracerebral bleeding?
hypertension
what is the bleeding classified as when it is inside the brain tissue/ruptures/bleeding occurs?
intracerebral
what is bleeding in the meninges classified as?
subarachnoid hemorrhage
give the locations where the subarachnoid hemorrhage occurs
between the skull and brain
why is a subarachnoid hemorrhage difficult to control?
because it is closer to the brain
what can subarachnoid hemorrhage mimick?
menigitis
what does SAH (subarachnoid hemorrhage) irritate?
irritates the meninges
the sign and symptoms of SAH
- sudden severe HA
- Nuchal rigidity
- Brudzinski’s sign
- Kernig’s sign
name the S&S of ICP
- decreased LOC and responsiveness
- fixed, dilated pupils
- VS: increased BP, decreased HR, widened pulse pressure meaning increased systolic and decreased diastolic
- Projectile vomiting
- Hiccups
name the two areas a hemorrhagic CVA can occur and what it causes
intracerebral
subarachnoid
causes increased ICP
