Confirm the flow is antegrade i.e. towards the head – (normal) or retrograde (suggesting subclavian steal syndrome).
Your health care provider will perform a physical exam. Your provider may use a stethoscope to listen to the blood flow in your neck for an unusual sound called a bruit. This sound may be a sign of carotid artery disease. Your provider also may find clots in the blood vessels of your eye.
If a carotid artery is patent, it means that the blood vessel remains open and unobstructed, allowing normal blood flow through it. A healthy, functioning carotid artery is crucial for supplying oxygen-rich blood to the brain. Blockages in this artery can lead to serious health complications such as stroke.
Presence of antegrade flow was significantly associated with large artery atherosclerosis as the cause of stroke. Rate of antegrade flow was much higher in patients with the large artery atherosclerosis subtype than in those with cardioembolism.
A normal physiological condition such as “patent” (meaning open) “antegrade flow” (meaning flowing forward) of the vertebral arteries” is not dangerous., rather it is totally appropriate.

Vessels were graded in 1 of 3 ways: patent without stenosis; patent with stenosis; or occluded (Table II). A grade of patent without stenosis was given to any vessel displaying no or only minor disturbances in color-flow characteristics and no stenoses of ≥50%.
