The risk of carotid plaque mainly lies in unstable plaque, which is unstable and easy to fall off on the blood vessel wall. When the plaque falls off in whole or in part, it becomes an embolus in the blood flow, which reaches the brain with the blood flow and blocks the distal cerebral artery, leading to embolic events. Depending on the size of the blocked blood vessel and the blocking time, it will lead to different results. Small blood vessel blockage is slight or asymptomatic, while large blood vessel blockage can lead to sudden hemiplegia and aphasia. If the blockage time is short, there will be short-term slurred speech, dizziness, numbness or weakness of limbs.
