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