Blood Vessels Pathology Flashcards
[syndrome]
gain of function of ENaC channel resulting to increased Na reabsorption and then hypertension
Liddle Syndrome
Associated condition
eosinophilic hyaline material with associated luminal narrowing
essential hpn
DM
[associated condition]
concentric, laminated thickening, onion skin lesion, note of fibrinoid deposition and vessel wall necrosis
malignant hypertension
location of neovascularization in an atheromatous plaque
periphery
[clinical phase of atherosclerosis]
mural thrombosis, embolization, and wall thickening can lead to
aneurysm and rupture
[clinical phase of atherosclerosis]
plaque rupture, plaque erosion, plaque hemorrhage, mural thrombosis, embolization can lead to
occlusion by thrombus
[clinical phase of atherosclerosis]
progressive plaque growth can lead to
critical stenosis
usually 70%
the larger the lipid core, the ____stability of the plaque
greater the stability of the plaque
Remember, size of lipid core is inversely proportional to stability
the lesser the degree of inflammation, the ____ stability of the plaque
greater stability
remember, degree of inflammation is inversely proportional to stability
the thicker the fibrous cap, the ___ stable the plaque
more stable the plaque
fibrous cap is directly proportional to stability
[dissection]
intima tear involvinf the descending aorta only.
What is the standford classification?

DeBakey III = Standford B
[aortic dissection]
Both ascending and descending aorta are involved.
What is it s debakey classification?
