De novo formation of blood vessels during embryogenesis?

vasculogenesis

2

the process of new vessel formation in the mature organism; neovascularization?

angiogenesis

3

remodeling of existing arteries in response to chronic changes in pressure or flow?

arteriogenesis

smooth muscle cells that are not contractile but able to divide?

neointimal

a clinically significant hypertension?

>139/>89

"hardening of the arteries" and loss of elasticity?

arteriosclerosis

8

a form of arteriosclerosis and an example of dystrophic calcification; affects medium muscular arteries of arms and legs?

Monkeberg's medial calcific sclerosis

9

characterized by intimal lesions called atheromas protruding into vessel lumens?

atherosclerosis

10

an acute phase reactant, downstream of a number of inflammatory triggers; induces a prothrombotic state; strongly predicts risk of MI or stroke?

C reactive protein

11

the major mechanism of atherogenesis?

hemodynamic disturbances, lipids, inflammation, infection

12

a localized abnormal dilation of a blood vessel or the heart?

aneurysm

13

aneurysm involving an intact attenuated arterial wall or thinned ventricular wall of the heart?

true aneurysm

14

defect in the vascular wall leading to an extravascular hematoma freely communicating with intravascular space?

false aneurysm

15

2 most important disorders predisposing to aortic aneurysms?

atherosclerosis and hypertension

16

aneurysms in the circle of willis?

berry aneuryms

the major risk factor of aortic dissection?

hypertension

the most common form of vasculitis in old people in US/Europe; chronic, granulomatous inflammation of large to small sized arteries predominately in head (nodular intimal thickening)?

giant cell (temporal) arteritis

19

tongue necrosis?

giant cell arteritis

20

a systemic vasculitis of small or medium sized muscular arteries; 30% associated with chronic Hep B?
