Carotid Duplex Examination using B-mode, color flow and spectral Doppler
(CPT: 93880)
INDICATION: Right carotid bruit
FINDINGS:
Right: B-mode imaging demonstrated no plaque formation within the common carotid
artery. Peak systolic velocity was 100 cm/sec. Heterogenous plaque was noted in the
proximal internal carotid artery with an elevated peak systolic velocity of 350 cm/sec,
end diastolic velocity of 150 cm/sec and ICA/CCA ratio of 3.5. The external carotid
artery had a peak systolic velocity of 128 cm/sec. The vertebral artery demonstrated
antegrade flow.
Left: B-mode imaging demonstrated no plaque formation within the common carotid
artery. Peak systolic velocity was 90 cm/sec. Heterogenous plaque was noted in the
proximal internal carotid artery with a peak systolic velocity of 120 cm/sec, end diastolic
velocity of 25 cm/sec and ICA/CCA ratio of 1.3. The external carotid artery had a peak
systolic velocity of 86 cm/sec. The vertebral artery demonstrated antegrade flow.
IMPRESSION:
1) Right carotid system demonstrates >70% stenosis of the internal carotid artery.
Compared to previous duplex, demonstrates progression of disease.
2) Left carotid system demonstrates <50% stenosis of the internal carotid artery.
No significant change from previous duplex.
3) Vertebral arteries demonstrate antegrade flow.
Preliminary result was phoned to Dr. Brown’s office prior to release of patient. S. Smart
