2-3 cm - ANS-What is the normal diameter for the abdominal aorta?
Claudication - ANS-After walking five minutes on treadmill, patient experiences
decrease in ankle pressures of 40% on right and 50% on left these finding suggest
AC-coupled output - ANS-What is the correct setting for arterial volume recording?
An absent flow recersal component, blunting of the peak velocity and prolonged upslope
and downslope. - ANS-What Doppler waveform abnormality in the lower extremity
arterial circulation distal to a hemodynamically significant stenosis show?
Reverse flow component:
It is part of arterial Doppler not volume waveform,
does NOT have zero baseline!
It does have - swift upstroke, sharp peak, rapid downslope bowed toward baseline,
dicrotic notch - ANS-A normal arterial volume waveform may have all except
There should be no change if normal. - ANS-What is a normal response of ankle
pressure to exercise testing
Markedly dampened, possibly making interpretation difficult for distal segments. -
ANS-With severe lower extremity arterial occlusive disease, how will distal Doppler
waveforms appear
65mmHg - ANS-What is the usual cuff Pressures used in arterial volume recording
Low-pitched and monophasic - ANS-What would the CFA signal look like with aortoiliac
occlusion?
False - ANS-True or false
diastolic flow reversal is always present in all abnormal limbs
The results are influenced by the patient's peripheral resistance - ANS-What is the most
important reason Doppler evaluation should be performed with patient in a basal state
and warm temperature
,Relatively high frequency with pulsatile components, and don't change with respiration -
ANS-Audible Doppler Venus signals are usually low frequency and vary with respiration,
whereas normal arterial signals in the arms and legs are ____
High frequency - ANS-When listening with continuous wave Doppler over a sonic lesion,
you will hear high frequency or low frequency sound?
>100% - ANS-A normal PORH response is a major velocity increase of what percent
increase in mean velocity
toe pressures - ANS-What are falsely elevated less frequently than tibial ankle
pressures?
A double-line appearance of the graft walls. - ANS-How can a PTFE graft be identified
during ultrasonographic imaging?
Higher
Lower - ANS-Velocities measured in a reversed saphenous bypass graft are usually
_____ proximally and ______ distally
The same throughout the graft, even though the velocities may differ - ANS-The volume
flow rate and a reversed saphenous vein bypass graph should be
Vasodilation opens to attempt to increase nutrive blood flow to the extremity and distal
resistance decreases. - ANS-With both arterial obstructive disease and distal ischemia,
what happens to vessel size and distal resistance?
Proximal to the point of insonation - ANS-When you have a damped Doppler velocity
wave form of the subclavian artery. Where would the significant lesion be located?
60-80mmHg - ANS-Normal values in TcPO2 assessment are
Pre-prandial to minimize shadowing due to bowel gas - ANS-AAA evaluation is done
pre or postprandial and why?
Triphasic, CFA and proximal SFA, with monophasic at the popliteal tibial arteries -
ANS-What wave forms will you likely see from CFA to tibial arteries with a superficial
femoral artery occlusion?
, Ankle pressure/The higher arm pressure. - ANS-When calculating the ABI pressure
ratio. What pressures are used?
Claudication is higher (0.5-0.9)
Rest pain is lower (< 0.5) - ANS-Which ABI would be higher between claudication and
rest pain
They decrease or disappear altogether - ANS-What happens to a patient's digital
pressure when the hand is immersed in cold water if they have reynauds disease
Coarctation of the aorta is a narrowing of the aorta, most commonly found just distal to
the origin of the left subclavian artery - ANS-Define coarctation of the aorta
a serious condition that involves increased pressure in a muscle compartment. It can
lead to muscle and nerve damage and problems with blood flow. - ANS-Define
compartment syndrome
a method in which radiographic images of blood vessels filled with contrast material are
digitized and then subtracted from images obtained before administration of the
material. The method increases the contrast between the vessels and the background. -
ANS-What is digital subtraction arteriography?
Common femoral artery - ANS-Where is the usual site for percutaneous lower extremity
angiography?
Aortoiliac, femoropopliteal, trifurcation arteries - ANS-The common radiologic terms,
inflow, outflow and runoff, refer respectively to what
Kidneys - ANS-Contrast for our choreography is hard on what organ
FMD - ANS-What condition shows up as a string of beats
Fibromuscular dysplasia-abnormal growth of cells in the walls of arteries that can cause
the vessels to narrow or bulge. The carotid arteries,are commonly affected. Arteries
within the brain and kidneys can also be affected. A characteristic "string of beads"
pattern caused by the alternating narrowing and enlarging of the artery can block or
reduce blood flow to the brain, causing a stroke. - ANS-What is FMD?
bifurcations - ANS-What is the kissing stent, angioplasty, stent, technique, useful for?
