It would seem that might be the case as I just had an MRI of my brain and it looks like I am missing the distal vertebral artery. My neurologist is sending me back for an MRI of my neck just to confirm if this is really the case.
Yes it is possible to be missing one of your vertebral arteries. After years of suffering memory loss and migraines as well as multitudes of symptoms that never made sense and under going medication therapies that weren't necessary I have the answer. I am completely missing my left vertebral artery. This was found during an ultrasound of my neck, and confirmed with an angiogram. We still have no course of action to follow for this but I will keep you updated if they find any new way to fix this problem!

A flow void is a place in the artery that's not showing any blood flow. Dominant suggests that there's one major area of missing flow.
The vertebral artery carries blood from the heart to the brain. An enlarged vertebral artery is usually caused by an accumulation of plaque that narrows the amount of blood flow to the brain causing memory loss or dizziness. An enlarged vertebral artery can also cause a sense of fullness near the ear, feels like water lodged in the canal.
An example of an artery which starts with a 'v' is the vertebral artery, which takes blood to the posterior portion of the brain.
