What is plaque in carotid artery

summary

At present, many elderly people will die of cerebral ischemia, which is a particularly dangerous thing. It is mainly caused by intracranial artery occlusion. Plaque in the carotid artery can form a large hard mass, which can lead to many diseases. Now let's talk about the plaque in carotid artery.

What is plaque in carotid artery

First, carotid plaque is the manifestation of carotid atherosclerosis, which is prone to occur at the bifurcation of common carotid artery. The mechanism of ischemic stroke may be as follows: carotid artery stenosis caused by plaque enlargement leads to intracranial hypoperfusion and plaque falling off to form embolus, leading to intracranial artery embolism.

Second: clinically, the degree of carotid artery stenosis and plaque morphology were measured to evaluate the carotid artery plaque and judge its harmfulness. Carotid plaque is a kind of massive structure caused by multiple risk factors, such as carotid artery wall injury and accumulation of visible components in blood flow. The risk of carotid plaques is not only the blockage of local carotid artery after growing up, which is a relatively long process after all.

Third: the risk of carotid plaque mainly lies in unstable plaque, that is, plaque that is not firm and easy to fall off on the vascular wall. When the whole or part of the plaque falls off, it becomes an embolus in the blood flow, and with the blood flow to the brain, it blocks the distal cerebral artery, leading to embolism events. According to the size of the blocked blood vessels and the blocking time, different results will be caused. The symptoms of small vessel blockage are mild or asymptomatic, while the large vessel blockage can lead to sudden hemiplegia, aphasia and other symptoms.

matters needing attention

Therefore, the plaque in carotid artery, that is, the large plaque formed on the inner wall of blood vessels, has no significant effect in the short term, but it will affect the normal flow of blood vessels in the long term. Can cause blood vessel blockage, which brings many dangerous factors. Therefore, it is helpful for patients to eat more food to soften blood vessels.
