CAROTID DUPLEX SCAN - 3

CAROTID DUPLEX SCAN

FINDINGS:               Duplex scanning of the carotid vessels shows atheromatous change involving the bilateral carotid system.  There is increased velocity seen in the right internal carotid artery and the ICA/CCA ratio of 2.3 in the right carotid system would suggest a stenosis of 60-79%.  The ICA/CCA ratio of 1.6 on the left would indicate a stenosis of 40-59% involving the left carotid system.

In view of the above findings, a carotid MRA would be indicated and of value.

IMPRESSION:         Severe stenosis of the right carotid system.

Thank you for the referral.
