Vascular surgeon: This is a decision that should be made by a vascular surgeon. Stenting or endarterectomy are often recommended for such an extensive carotid artery blockage even in the absence of symptoms. Occasionally such patients without symptoms are placed on daily aspirin and followed closely for any warning symptoms.

Yed: Yes get blockage treated by surgery or stent to reduce risk of stroke
