Question | Answer |
What is the most common symptom of peripheral arterial disease? | Claudication |
What are the most common sites for atherosclerotic disease? | Bifurcations, trifurcations, and vessel origins (eg: SFA at adductor canal, infra-renal aorto-iliac system) |
In the lower extremities, a ____% stenosis is considered hemodynamically significant | 50% |
Describe the "stenosis profile" | Dampened velocities - proximal to stenosis Increased velocities - at stenosis Spectral broadening – distal to stenosis Post-stenotic turbulence |
Describe the difference between the 3-cuff and 4-cuff methods | The 3-cuff method is more accurate. The 4 cuff method – will artificially elevate thigh pressures, but will localize disease more than 1 cuff would |
How should one select an appropriate cuff size? | Bladder of cuff should be 20% wider than limb diameter |
Cuffs should be inflated ____-____ mmHg above the last audible Doppler signal | 20-30 mmHg |
What are you looking for when interpreting a segmental pressure study? | Look for a 30 mmHg or greater pressure drop side-to-side or in adjacent segments |
What ABI would suggest multi-level disease? | < 0.5 |
With an abnormal PVR, where is the disease? | An abnormal PVR will always mean that there is disease proximal to the waveform |
