[edit] Sample Dictation

Clinical statement: []


Technique: A sonogram of the common and internal carotid arteries was performed with a linear transducer with color and spectral Doppler supplementation.


Comparison: []


Findings on the right:

No visualized narrowing is seen in the common carotid or internal carotid arteries.

Peak systolic velocities in meters per second:

Right common carotid artery: [ ]

Right internal carotid artery: proximal [ ], mid [ ], distal [ ]

Right external carotid artery: [ ]

Right ICA /CCA ratio: [ ]

Right vertebral artery: normal cephalad flow


Findings on the left:

No visualized narrowing is seen in the common carotid or internal carotid arteries.

Peak systolic velocities in meters per second:

Left common carotid artery: [ ]

Left internal carotid artery: proximal [ ], mid [ ], distal [ ]

Left external carotid artery: [ ]

Left ICA /CCA ratio: [ ]

Left vertebral artery: normal cephalad flow


Impression: No sonographic evidence of hemodynamically significant narrowing of the above arteries.

[edit] Numbers to know for Carotid Artery Stenosis sonograms

1. Peak systolic velocities of ICA < 1.25 m/sec and peak systolic velocity ICA/CCA ratios <2:1 correspond to 0-50% stenosis.

2. Peak systolic velocities of ICA > 1.25 m/sec but < 2.25 m/sec and peak systolic velocity ICA/CCA ratios >2:1 correspond to 50-75% stenosis.

3. Peak systolic velocities of ICA > 2.25 m/sec but < 3.25 m/sec and peak systolic velocity ICA/CCA ratios >3:1 correspond to 75-90% stenosis, which is hemodynamically significant.

4. Peak systolic velocities of ICA > 3.25 m/sec and peak systolic velocity ICA/CCA ratios >4:1 correspond to >95% stenosis, which is hemodynamically significant.
