1. S-shaped vessel =: tortuous
2. tortuous vessels have what type of symptoms ?: asymptomatic
3. sharp turned vessel =: kinking
4. Kinking vessels have what type of symptoms?: stroke like
5. circle (looped) vessel =: coiling
6. is consistent with cerebral ischemia.: kinking
7. What percent of adults will have some degree of angulated vessels?: 25% (1/4)
8. Is angulation of the vessels usually uni- or bilateral?: bilateral
9. Will velocities be high or low in the curves of angulated arteries?: high
10.What are the signs and symptoms of turtuous, kinking, and coiled arter- ies?: asymptomatic
TIA/stroke symptoms pulsatile
mass
11.Which angulation is more likely to cause a stroke, why?: kinking, head turning
12.Which angulation is more related to a pulsatile mass?: turtuous
13.Which vessel is more commonly associated with a pulsatile mass?: CCA
14.What will color look like in an angulated artery?: aliasing
15.How will you determine if an angulated artery is stenotic?: Doppler before and after curves to check
waveforms (PST, tardus parvus)
16.What is extremely helpful in following tortuous arteries?: color
17.Do high velocities in an angulated artery indicate stenosis?: no
18.Should you doppler pre and post curve/kink velocites?: yes
19.What is the best indicator of a hemodynamically significant stenosis in a tortuous vessel?: post stenotic
turbulence
20.Separation of the layers of an artery due to intimal tear =: dissection
21.What is the most common way an artery typically tear in a dissection?: in- tima to media

22.flow in a tubular structure =: laminar flow
23.What may a dissection lead to?: pseudoaneurysm and thrombus formation
24.What is the hallmark sign of a dissection?: intramural hematoma with luminal narrowing or occlusion of true
lumen
25.what is the best way to guarantee a dissection?: Doppler true and false lumen
26.What are the false lumen flow patterns?: antegrade (bc of secondary tear) to and fro
retrograde
no flow (thrombus, stenosis, occlusion)
