Vascular ultrasound exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
Which waveform would cause you to image the iliacs whilst scanning the CFA? - Correct
answers✔✔monophasic, tardus parvus
if a stenosis is <5 cm which treatment plan is best? - Correct answers✔✔endovascular
intervention
Documentation of common 2D B-mode findings at a site of angioplasty do not include:
a) stent deformation
b) plaque characteristics
c) intimal thickening
d) pseudoaneurysm - Correct answers✔✔d; color doppler
B-mode is done to assess lumen patency, vessel size..
less than 50% stenosis at aortoiliac area.. CFA what findings?
a) monophasic
b) high resistance
c) multiphasic - Correct answers✔✔multiphasic
Diffuse in-stent stenosis findings - Correct answers✔✔inc velocity ratio
inc PSV
lumen reduction on cd OR pd
, perforating veins - Correct answers✔✔Connect the superficial and deep venous system, contain
valves!
position for lower extremity venous ultrasound - Correct answers✔✔straight but slightly tilted
with head tilted elevated
best way to determine if a vein is thrombus free - Correct answers✔✔compress the walls
completely by transducer; coapt the vein
imaging of iliac vein is done when CFV waveform - Correct answers✔✔CFV doppler signals are
continuous
Normal phasicity waveform - Correct answers✔✔stop during inhalation
Pulsatile venous Doppler from the lower extremity veins may suggest: - Correct answers✔✔AVF
CHF
pulmonary hypertension
Virchow's triad - Correct answers✔✔Stasis, hypercoagulability, endothelial damage
all of the following associated w DVT except:
- chest pain
- lower extremity, swelling
- discoloration
- calf pain, tenderness - Correct answers✔✔chest pain--> PE
