- Q1
The spectral waveforms observed in the proximal aorta will have different characteristics from the distal aorta due to:
the proximal aorta is larger than the distal aorta, which impacts the diastolic components
the proximal aorta is closer to the heart, which will impact the flow during diastole.
The proximal aorta supplies the visceral arteries, which supply lower resistant vascular beds like the liver and kidneys.
there are more branches in the distal aorta
30s - Q2
A type 1 endoleak refers to:
Flow at the attachment/fixation site(s)
inferior mesenteric artery or lumbar artery branch flow
graft porosity
enlarging aneurysmal size
30s - Q3
The most accurate aortic measurement is made when:
The diameter measurement includes anterior to posterior wall measurement from a perpendicular approach to the ao
plaque is not present within the ao lumen
trans left to right
the transucer is in a true trans or long position to the patient
30s - Q4
What is the term applied to the ao where there are areas of dilation less than 3cm or irregular margins and a nontapering profile?

monophasic Doppler spectrum with low resistance and moderate end diastolic flow
30s - Q10
When assessing for celiac artery compression during the duplex ultrasound, one should compare:

generalized abdominal pain and bloating starting 10 to 15 mins after eating
epigastric or periumbilical pain starting about 30 mins after eating
30s - Q12
The normal Doppler waveform of the celiac artery is:
