Carotid stenosis is one of the major causes of stroke. This occurs when the walls of the major vessels supplying the brain become partially obstructed or blocked. Plaque can form on these walls or a blood clot can become lodged. The common treatment for this problem is a vascular procedure where a balloon is forced through the vessel to help clean out the blockage, or a stent can be placed to help open the vessel more. If the problem is caught early it can be resolved without and permanent damage.,
