OPINION:
USG scan suggests –  No evidence of stenosis in carotid arteries, vertebral arteries of both sides.
Normal intima-medial thickness seen in carotid arteries.
Normal flow seen in carotid and vertebral arteries.

SUGGEST: clinical correlation and follow up.
CT or MRI angiography may be done to confirm these findings.




REFERENCE:

CRITERIA FOR CAROTID STENOSIS :

PSV:

·  Normal: ICA PSV <125 cm/s and no plaque or intimal thickening is visible.
·  <50% stenosis: ICA PSV <125 cm/s and plaque or intimal thickening is visible.
·  50-69% stenosis: ICA PSV is 125-230 cm/s and plaque is visible.
·  >70% stenosis to near occlusion: ICA PSV >230 cm/s and visible plaque and lumen narrowing are seen
