Bilateral Doppler Study: Carotid Arteries

Bilateral Doppler Study: Carotid Arteries
Indications: Status post-carotid endarterectomy imaging. The patient states that he was told that the right carotid artery is blocked. The right internal carotid artery is not identified, probably completely blocked.
Velocity measurements on the right side:
Common carotid artery: 58.9 cm/sec
Right external carotid: 142 cm/sec
Right vertebral: 44 cm/sec and showing antegrade flow
Velocity measurements on the left side:
Common carotid artery: 35 cm/sec
Carotid bulb: 60 cm/sec
Internal carotid: 52 cm/sec
External carotid: 236 cm/sec
Left vertebral: 55 cm/sec
Status postendarterectomy changes are noted in the left internal carotid and the bulb. There is evidence of ectasia. On the right, the common carotid artery shows ectasia.
Judging from the velocity measurements, the right internal carotid artery has a stenosis in the range of 50% to 79%.
The left internal carotid artery has a stenosis in the range of 16% to 49%. The left external carotid artery is in the range of 50% to 79%.
Impression: The right internal carotid artery is completely occluded. Status postendarterectomy changes in the left internal carotid and the bulb are noted. No significant occlusive disease is seen in the left internal carotid artery. Both vertebral arteries are showing antegrade flow.
