The article covers vascular disease. Vasculitides are covered in a separate article called vasculitides.
Great vessels
When things go wrong here, you see a cardiac surgeon.
Atherosclerosis
General
- Cardiac atherosclerosis -> myocardial infarction, coronary thrombosis.
- Peripheral atherosclerosis -> peripheral vascular disease -> amputations.
- Carotid atherosclerosis -> thrombotic stroke.
Clinical risk factors:
- Age.
- Blood pressure - modifiable (antihypertensives).
- Cholesterol - modifiable (statins, diet).
- Diabetes mellitus - modifiable (hypoglycemic medications, diet, lifestyle).
- Smoking - modifiable (cessation).
- Family history.
Microscopic
Features:
- Intimal hyperplasia.
- Lipid deposition.
- Foam macrophages within intima & media.
- Cholesterol clefts
- Luminal narrowing.
Aortic dissection
Associations
Heritable:[1]
- Marfan's syndrome.
- Loeys-Dietz syndrome.[2]
- Marfan-like syndrome.
- Ehlers-Danlos syndrome.
- Bicuspid aortic valve.
Others:
- Tertiary syphilis.
Cystic medial degeneration
General
Microscopic
- Basophilic ground substance in the media (seen on Movat's stain).
- Disruption of the elastic lamina (seen on elastic trichrome stain).
- +/-Focal necrosis.
Images: Marfan's syndrome (radiographics.rsna.org).
Medial calcific sclerosis
- AKA Moenckeberg medial calcific sclerosis.
General
- Usually of no clinical consequence.
Microscopic
Features:[6]
- Medial calcification (purple irregular stuff -- calcium phosphate).
Note:
- Lumen unaffected.
