WELCOME TO THE ARTERIOVENOUS MALFORMATION (AVM) COMMUNITY: This Patient-To-Patient Community is for discussions relating to Arteriovenous Malformations, which are defects of the circulatory system that are generally believed to arise during embryonic or fetal development or soon after birth. They are comprised of snarled tangles of arteries and veins.

What Does a Carotid Ultrasound Show?
A carotid ultrasound can show whether buildup of a fatty material called plaque has narrowed one or both of your carotid arteries and reduced blood flow to your brain.
The illustration shows a normal artery with normal blood flow (figure A) and an artery containing plaque buildup (figure B).
If your carotid arteries are narrowed by plaque, you may be at risk for having a stroke. That risk depends on how much of your artery is blocked and how much blood flow is restricted. To reduce your risk for stroke, your doctor may recommend medical or surgical treatments to reduce or remove the plaque buildup in your carotid arteries.
