compression
Rest pain is found in patients with an ABI score less than - answer✔✔0.5
Abnormal Allen test - answer✔✔when the radial artery is compressed and very little flow is seen
to the hand
ulnar artery is occluded
palmar arch is not patent
Lower extremity veins that do not contain valves - answer✔✔IVC, Iliac veins and Soleal sinuses
Upper extremity veins that do not contain valves - answer✔✔SVC and innominate veins
Arteriography is the most sensitive test for arterial disease - answer✔✔T
_____% diameter or ____% area of a vessel is considered to be hemodynamically significant
stenosis - answer✔✔50, 75
A double peaked wave tracing is indicative of - answer✔✔vasospasm due to Raynaud's
syndrome
Veins that do not normally demonstrate spontaneous flow on pulse wave ultrasound exams -
answer✔✔PTV's, peroneals, GSV
Normal PBI - answer✔✔greater than or equal to 0.75
Vasculogenic impotence is diagnosed with a PBI of - answer✔✔<0.65

The ultrasound eval of a TIPS procedure should be performed within _____ hours of the
operation to establish baseline values for serial exams - answer✔✔24
Negative Predictive Value (NPV) - answer✔✔number of correct neg dx / number of neg dx
made
The PI of the normal aorta should be _____ than the PI of the popliteal artery - answer✔✔less
A PI of <______ indicates proximal obstruction - answer✔✔5
Difference in protocol for hemodialysis graft vs hemodialysis fistula - answer✔✔graft- two sites
of anastomosis,
fistula- one site of anastomosis (protocol is the native artery prior to anastomosis, anastomosis
site, vein distal to anastomosis
When using the GSV as an in situ graft, all _______ must be marked down the leg so that they
can be closed - answer✔✔perforators
What would cause the ECA to have reverse flow in systole? - answer✔✔left CCA occlusion
the flow reversal from the ECA will provide the ICA with flow because the CCA cannot
An increase in aortic sac diameter of ______ cm or greater indicates a possible endoleak -
answer✔✔0.5
Stages of restenosis after endarterectomy procedure - answer✔✔first month post op- suboptimal
surgical techniques
24 months post op- neointimal hyperplasia
2 years post op- progression of atherosclerotic disease
reactive hyperemia - answer✔✔a bright red flush on the skin occurring after pressure is relieved
Velocities are usually higher at the proximal anastomosis site of a _____ ______ ______ because
the diameter of the graft increases distally - answer✔✔reversed in situ graft
Vasodilation will cause a triphasic waveform to become ______ - answer✔✔monopahsic
vasodilation lessens resistance, lessened resistance causes a more monophasic waveform
PW doppler is preferred over CW to determine the location of a stenosis in a vessel because CW
has no depth resolution and is preferred for higher velocities - answer✔✔T
Ascending venography - answer✔✔uses contrast that is injected at the ankle and the course is
follow up the leg to assess for DVT
