    Treatment for asymptomatic carotid stenosis aims to reduce the risk of stroke. For most people, this can be achieved by medical management. People who are at higher risk of stroke may be offered revascularisation. CEA is the standard technique and involves a cut on the side of the neck. CAS is an alternative when CEA is unsuitable.
