CAROTID DUPLEX STUDY

CAROTID DUPLEX STUDY

FINDINGS:             Mixed plaque formation is seen involving the bulbar region of both common carotid arteries and proximal internal carotid arteries bilaterally.

The velocity of the blood flow in the right common carotid artery is 64 cm/sec, in the right internal carotid artery it is 54 cm/sec, and in the right external carotid artery it is 70 cm/sec.

The velocity of the blood flow in the left common carotid artery is 64 cm/sec, in the left internal carotid artery it is 70 cm/sec, and in the left external carotid artery it is 55 cm/sec.  These values are within normal limits.

Antegrade blood flow was seen in the vertebras.

The ICA/CCA ratio on the right is 0.83 and on the left, it is 1.10 and these values are within the normal range.

IMPRESSION:        About 40% stenosis of proximal right internal carotid artery and about
40-50% stenosis of proximal left internal carotid artery, not hemodynamically significant.

Thank you for the referral.
