NP2C Flashcards
What commonly gives rise to hemorrhagic infarcts in humans?
Atherosclerosis
Human type of infarction is not as common in domestic animals, but we can see it occasionally in _______________
hypothyroidism
could cause blood clot formation within the vessel, that could disrupt blood flow, diminish blood flow, causing infarction, and the fact that the blood vessel is inflamed means that it also will leak, so hemorrhagic infarct
Vasculitis
can affect small vessels in such a way that ultimately they will burst, giving rise to a large hemorrhagic infarct
Hypertension
When you have multi-focal insults of GM, this is very consistent with an insult coming from the blood supply, particularly __________
Septic Emboli (Actually carrying microorganisms)
is something that forms in a distant tissue
embolus
likes to grow into blood vessels
Histophilus somni
the cavitation tells you that you have _________
pannecrosis
runs on the floor of the spinal canal
ventral spinal artery
enter from the periphery to create a network of blood vessels that course along the surface of the spinal cord, sending branches that supply the WM
intercostal arteries
Fibrocartilagenous embolus can be seen in:
dogs and camelids, cats, horse and pigs
if it increases slowly, that increased pressure can diminish blood supply to the cerebral cortical grey and get ________ atrophy
GM
What are potential causes of a hemorrhagic infarct?
- vasculitis with thrombus formation
- compression sufficient to collapse veins but not arteries and arterioles
- trauma resulting in laceration of blood vessels
What predisposes GM to infarction?
- higher vascular density in GM vs WM
- reliance of some GM on an end arterial blood supply
