What is the carotid artery?
A blood vessel which comes off the arch of the aorta and supplies blood to the brain, head and neck. The main trunk is called the common carotid artery. It then separates into the internal carotid artery (which supplies blood to the brain) and the external carotid artery (which supplies blood to the face, neck and scalp).
Why is it important?
When severely narrow, it may account for approximately 25% of all strokes.
What is a carotid ultrasound?
A non-invasive method of determining carotid artery disease. It does not
require radiation and is an excellent screening tool. If additional testing is needed we
may consider alternative testing. These tests help to define the extent of disease in the
These tests include:
Ultrasound of the Carotid Magnetic Resonance
Carotid Artery Angiogram (MRA)
Carotid Artery CT Scan (CTA) Carotid Artery Angiogram
with high grade bifurcation
Do all patients require treatment?
Most patients with carotid artery disease are initially placed on antiplatlet therapy, such as aspirin.
The addition of this medication, as with all medication, should always be discussed with your medical doctor to make sure that you have no contraindication to the medicine.
If the disease is not associated with neurologic findings, the Asymptomatic Carotid Artery Study (ACAS) describes those that benefit to include patients with at least 60% or greater stenosis of the internal carotid artery.
If the disease is associated with neurologic findings, the North American Symptomatic Carotid Endarterectomy Trial (NASCET) describes those that benefit to include patients with at least 50% or greater stenosis of the internal carotid artery..

anesthesia we place a shunt which allows blood to
flow to the brain while the operation is in progress.
