- What Can Be Done About Stenosis (Narrowing) of the Carotid Artery?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I have two questions for you. I have been diagnosed as having
- stenosis (narrowing) of the carotid artery. What, if anything, can help this
- problem? Am I in a no win situation? I am very upset and feel as though I am
- sitting on a time bomb. I would appreciate any help you can provide on this
- subject.

- ANSWER: It depends a bit upon your past history and whether or not you have
- had any symptoms. The carotid arteries, one on each side of the neck, are
- major vessels which run from the main arteries of the body (the aorta on the
- left and the innominate artery on the right) to feed the network or arteries
- in the brain with oxygen rich blood. When the inside walls of the carotids
- become the site of collections of fatty deposits (atherosclerosis), the
- passage way for blood is closed down. Less blood makes its way to the brain,
- with the result that there are insufficient supplies of oxygen (ischemia), and
- a stroke can result when smaller arteries are completely blocked off by a
- blood clot. However, these narrowed places in the arteries can be opened
- through a surgical procedure called endarterectomy, during which the surgeon
- removes the fatty plaques. It is not an easy operation and it involves a
- significant risk. Therefore surgeons usually do not recommend the surgery
- unless there is evidence that the patient is a greater risk of having a
- stroke, than the risk related to the surgery itself. For patients who have
- already suffered a transient ischemic attack (TIA) or a nondisabling stroke,
- and have a 70 percent or greater narrowing of the artery, the operation is
- considered "highly beneficial". For the many patients who have some narrowing
- but no symptoms, the decision is less easy to make. The vast majority of
- these patients never do go on to strokes, in which case the risks of the
- operation outweigh its positive results. Other arteries which run around the
- site of blockage (collateral circulation) may make up for the blocked artery,
- and provide the needed oxygen to the brain in any case. In addition there are
- studies currently under way which seek to measure the use of aspirin to
- prevent strokes, and to compare the results of this medical treatment to those
- obtained with surgery. You may not be sitting on a time bomb, but the correct
- treatment will depend upon the results of your history, tests and
- examinations.
