Carotid stenosis is also known as carotid artery stenosis and is a medical condition where the carotid artery that supplies blood from the heart to the brain is narrowed or blocked. The carotid arteries are located on each side of the neck and blockages are caused by a build-up of plaque, which is is made up of fatty deposits, calcium and cholesterol. Small amounts of these substances can be stuck within a blood vessel and can build up and cause a blockage and damage to the arteries over time.
The reduction to the supply of oxygen and nutrients to the brain can lead to a stroke, permanent brain damage or even death if not treated in time.
Sudden confusion and difficulty talking or understanding speech
Sudden weakness or numbness of one side of the body

An coronary angiography may be done to check for narrowed or blocked arteries.
