What should be my concern for carotid stenosis with the below results

Posted by pagekt56 @pagekt56, Mar 23 8:57am

I am a 69 year old female and am told I have a 50% carotid stenosis. I had this done as a result of having migraines since age 26. I switched to a new neurologist who requested a new carotid ultrasound and below are the results. Can someone tell me what level of stenosis I have?
RIGHT:
ICA Velocity:
Peak systolic 85 cm/sec
Peak diastolic 39 cm/sec

CCA Velocity:
Peak systolic 82 cm/sec
Peak diastolic 29 cm/sec

ECA Velocity:
Peak systolic 70 cm/sec

ICA/CCA Ratio: 1.0

Vertebral 60 cm/sec
Flow antegrade

LEFT:
ICA Velocity:
Peak systolic 92 cm/sec
Peak diastolic 39 cm/sec

CCA Velocity:
Peak systolic 82 cm/sec
Peak diastolic 29 cm/sec

ECA Velocity:
Peak systolic 74 cm/sec

ICA/CCA Ratio: 1.1

Vertebral 46 cm/sec
Flow antegrade

FINDINGS: Carotid bifurcations are widely patent and flow in both vertebral arteries is
antegrade.

IMPRESSION:
NORMAL BILATERAL CAROTID SONOGRAM.

I googled this:

Definitions of 'patent' - and one of them is as follows: medicine
(of a vessel, duct, or aperture) open and unobstructed; failing to close:
"the patient is usually left with a patent vessel"

So, apart from interpreting all those numbers, the declaration at the end of the quoted text of yours suggests that you are in good shape, all things considered. You are always welcome to find another specialist and ask for either his/her interpretation of this finding, or to order another set of tests for you for his/her own edification and advice to you.
