1
New cards

most common reason for underestimation of arterial stenosis

improper sample volume location

2
New cards

as area of a vessel decreases, flow velocity ______

increases

3
New cards

in the presence of stenosis, where is the highest velocity located

within the stenosis or just distal to the stenosis

4
New cards

pre stenotic zone

  • increased resistance, resistive index

  • flow velocity may be damped w loss of diastolic flow

  • short acceleration time

5
New cards

within stenotic zone

  • high PSV

  • increased diastolic flow

  • decreased pressure

  • spectral broadening

6
New cards

post stenotic zone

  • turbulence

  • low resistance flow

  • increased diastolic flow

7
New cards

distal to critical ICA stenosis

  • diastolic/systolic flow is low velocity w blunted waveform

  • slow acceleration time

  • tardus parvus
