A abrupt stoppage of blood flow to a brain artery is the most prevalent cause of a stroke. The blockage is frequently caused by plaque or a clot that has travelled to the brain from the carotid artery in the neck. If the narrowing or blockage of the carotid artery is significant, it is usually treated with surgery to avoid a stroke. A procedure known as Carotid Endarterectomy can be used to clear the obstruction.
