A build-up of plaque in your carotid artery reduces blood reaching the brain, and in the worst circumstances, can cause a stroke. Over time, as the plaque progresses, your arteries become stiff and can narrow to the point that serious health problems arise.
Carotid stenting allows the doctor to fit a small, mesh-like steel tube in your carotid artery to re-establish the blood flow. Stenting may be recommended for people who are unable to undergo surgical removal of the plaque in their arteries. Advanced age, severe congestive heart failure, and problems with other blood vessels may influence whether the implantation of a stent is appropriate.
