Atherosclerosis Flashcards
what is this?
artherosclerotic plaque (notice cholesterol clefts on inside - the white streaks)
what is this?
mockeberg medial calcification
what is this?
arteriolosclerosis - with hyaline change
what is this?
atherosclerosis with calcified cholesterol in center
what is this?
onion skin appearance - hyperplastic arteriolosclerosis
what is this?
Aorta with fatty streaks
what is going on here?
fatty streak with macrophage-derived foam cells
what is this?
(atherosclerotic lesions) Aorta with mild atherosclerosis composed of fibrous plaques, one denoted by the arrow
what is this?
Atherosclerotic lesions
Aorta with severe diffuse complicated lesions, including an ulcerated plaque (open arrow), and a lesion with overlying thrombus (closed arrow)
what is this?
Atherosclerotic plaque in the coronary artery
Overall architecture demonstrating fibrous cap (F) and a central necrotic (largely lipid) core (C); collagen (blue) is stained with Masson trichrome. The lumen (L) is moderately narrowed by this eccentric lesion, which leaves part of the vessel wall unaffected (arrow)
what is shown here?
Moderate-power view of the plaque shown in A, stained for elastin (black); the internal and external elastic membranes are attenuated and the media of the artery is thinned under the most advanced plaque (arrow).
what is shown here?
High-power view of the junction of the fibrous cap and core, showing scattered inflammatory cells, calcification (arrowheads), and neovascularization (small arrows).
what is shown here?
Atherosclerotic plaque rupture without superimposed thrombus, in a patient who died suddenly
what is shown here?
Acute coronary thrombosis superimposed on an atherosclerotic plaque with focal disruption of the fibrous cap, triggering fatal myocardial infarction
