OPINION:
USG scan suggests – No evidence of stenosis in carotid arteries,
vertebral arteries of both sides.
Normal intima-medial thickness seen in common carotid
arteries.
Normal flow seen in carotid and vertebral arteries.
A small plaque of 1.7 mm. thickness seen in 2 mm. area of
the lateral aspect of the left internal carotid artery close to origin. No
significant stenosis is present.
SUGGEST: clinical correlation and follow up.
CT or MRI angiography may be done to confirm these findings.
