Answer 16

fistula

Question 17

When is it ideal in the ab Ao to use a panoramic feature or at least measure the longest field of view possible.

Why?

Answer 17

length of aneurysm in long

• to see entire length an aneurysm
• to see if other arteries may be compromised

Question 18

stationary blood clot along wall of vessel, usually causes vascular obstruction

Answer 18

thrombus

Question 19

With AAA in trans what needs to be measured?

Answer 19

diameter of aneurysm and also the remaining lumen

Question 20

Distension of lumen by aneurysm may induce low flow and turbulence possibly increasing……

Answer 20

risk of thrombosis

Question 21

It has a “seagull” appearance

Answer 21

Celiac/Coeliac Axis

It has a “seagull” appearance with the hepatic artery going towards the liver and the splenic artery to the left.

False dilation created from flow escaping from an artery and contained within surrounding tissue.

Answer 22

Pseudoaneurysm

Question 23

Where does a dissection usually occur?

Answer 23

between intima and media layers of an artery

Question 24

What is the difference between pseudoaneurysm and aneurysm?

Answer 24

pseudoaneurysm should not have a vessel wall and should not show signs of arterial layers

Question 25

Describe Doppler waveform of an aneurysm

Answer 25

medium-to-high resistance flow pattern in lumen

Question 26
