Vascular ultrasound exam UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Which waveform would cause you to image the iliacs whilst scanning the CFA? - CORRECT
ANSWER - monophasic, tardus parvus
if a stenosis is <5 cm which treatment plan is best? - CORRECT ANSWER - 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 ANSWER - 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 ANSWER - multiphasic
Diffuse in-stent stenosis findings - CORRECT ANSWER - inc velocity ratio
inc PSV
lumen reduction on cd OR pd
perforating veins - CORRECT ANSWER - Connect the superficial and deep venous
system, contain valves!
, position for lower extremity venous ultrasound - CORRECT ANSWER - straight but
slightly tilted with head tilted elevated
best way to determine if a vein is thrombus free - CORRECT ANSWER - compress the
walls completely by transducer; coapt the vein
imaging of iliac vein is done when CFV waveform - CORRECT ANSWER - CFV doppler
signals are continuous
Normal phasicity waveform - CORRECT ANSWER - stop during inhalation
Pulsatile venous Doppler from the lower extremity veins may suggest: - CORRECT
ANSWER - AVF
CHF
pulmonary hypertension
Virchow's triad - CORRECT ANSWER - Stasis, hypercoagulability, endothelial damage
all of the following associated w DVT except:
- chest pain
- lower extremity, swelling
- discoloration
- calf pain, tenderness - CORRECT ANSWER - chest pain--> PE
D-dimer and DVT? - CORRECT ANSWER - elevated with DVT
false positive
