A member asked:

Could blocking only one of the left and right common carotid arteries lead to complete brain death?

A doctor has provided 1 answer

Unlikely: The blood flow to the brain comes from anterior circulation, the carotids, and posterior, the basilar branching into the 2 vertebrals. Complete unilateral carotid thrombosis could cause a significant stroke but the collateral circulation could mitigate the damage, and preserve substantial function.
