Pathology of Ischemic CV Disease Flashcards
What are the major anatomic components of elastic arteries?
Accommodates/dampens pulsatile blood flow
e.g. aorta
What are the major anatomic components of muscular arteries?
Regulates blood flow
- Vasoconstriction/dilation
- E.g. renal arteries
What is cystic medial necrosis?
a
What is the primary complication associated with cystic medial necrosis?
a
What are the diseases associated with elastic fiber and collagen synthesis defects that can manifest with cystic medial necrosis?
a
a
a
Define arteriosclerosis
a
What are the two subcategories of arteriosclerosis?
a
What is the disease process of arteriolosclerotic disease?
a
What is the disease process of atherosclerotic disease
- Focal chronic endothelial injury
- Lipoproteins trapped in vessel wall
- Cellular interactions w/ macros, lymphocytes (rxn to lipoproteins)
- Proliferation of SMCs
What are the risk factors for developing arteriosclerotic disease?
a
What are the risk factors for developing atherosclerotic disease?
a
What are the complications associated with arteriosclerotic disease?
a
What are the complications associated with atherosclerotic disease?
a
Define aneurysm
- Weakening of vessel wall
Causes:
- Trauma
- Local infections (mycotic)
- Congenital defects (berry)
- Arteriovenous aneurysms
What are the two disease processes involved in aneurysm formation?
- HTN
- Atherosclerosis
Define pseudo-aneurysm
- actual wall is fine
- outside tissue has formed a hematoma
What is an example of a pseudo-aneurysm
Hematoma
Define the term dissection with respect to the aorta or other arteries
aortic dissection?
What is the key disease process underlying dissection (hypertension -> cystic medial necrosis)?
a
What are the sites where dissecting blood may drain into?
- Pericardium
- Thorax
- Peritoneum
?
What are the names of when is present in the pericardium, thorax, and peritoneum?
- Hemopericardium
- Hemothorax
- Hemoperitoneum
What is a manifestation of tertiary syphilis? (think vessels)
Ascending aorta/aortic arch aneurysm
What are the names of types of vessels comprising key vascular malformations?
a
