Carotid doppler ultrasound showed elevated psv in right ica but normal ica/cca. what's this mean?

See detailed answer: Psv = peak systolic velocity (i.e. Speed of blood flow); elevated psv can indicate narrowing ica/cca ratio is another way of assessing narrowing - would need to see actual numbers my 2 cents...See a vascular surgeon.

Dr Wu agreed

Carotid Ultrasound: An elevated peak systolic velocity (psv) would suggest a narrowing of the carotid artery, however this is only one of the criteria used to determine the degree of blockage in the carotids. In many vascular ultrasound practices a psv > 125 cm/s, ica/cca > 2.0, and visualization of plaque on ultrasound suggests at least a 50% blockage. Discuss your ultrasound with a vascular surgeon.
