Q

What are the spectral analysis ultrasound findings of an ICA occlusion?

A

No Doppler flow
ECA and CCA will have similar waveforms

Q

If there is an abnormal Doppler waveform in the ICA, where would that suggest disease at?

A

A high resistance ICA waveform may also occur with stenosis in the distal ICA. However, condition usually coexists with extensive disease in the proximal ICA.
