Treatment for bilateral carotid artery calcifications?

None. Calcification of any artery, by itself, does not warrant any type of intervention or follow up. If that calcification is associated with a stenosis ("narrowing") of the artery, then that may require follow up and/or an operation. The carotid arteries are very often calcified and if associated with a high grade stenosis, may portend a higher risk of stroke. Discuss with a vascular surgeon.
