Patho Flashcards
What do the call reabsorption of clot
Liquefaction necrosis
Why is stroke called the final common pathway
All mechanism lead to stroke
Divine Tia
Symptoms without damage on MRI
Percent of catdoembolic
20 to 30%
Artery to artery embolism percentage
15 to 20 percent
Percent of small vessel
20 to 30
What happens 5 to 10 days after stroke
The infarct becomes demarcated from the unaffected brain
Segregation
What can trigger a stroke with stenotic vessel 4
Hypoperfusion
Heart output stop
Fever acidosis
Carbon dioxide retention
Define small vessel stroke
Penetrating artery occlusion
Cause of small vessel occlusion
Lipo hy alin osis
What is lipohyalinosis
Vessel wall is turned into fibrin and collagen
What is responsible for large subcortical infarcts
Microatheroma
What is a small vessel aneurysm called
Charcot Bouchard
What causes increase in blood pressure with stroke
Lack of auto regulation
Normal range of cerebral perfusion
40 to 60 ml /100 mg /min
Tpa may work best for what type of strokes
Cortical
White matter and nasal ganglia might be a diff strory
Is gray or white matter more likely to infarct
Gray.
Gray in striatum is more likely to stroke than white matter in bg
Ischemic core means
Tissue that is irreversible damaged
What do you call radiation affect on the brain
Radiation induced vasculopathy
How occluded does vessel need to be to show Hemiparesis
50%
If cbf gets below what blood flow it is no longer structurally salvageable
