How does a cerebral infarction form?

Cerebral infarction generally refers to cerebral infarction, cerebral infarction is considered to be caused by atherosclerosis, cardiogenic embolism, small artery occlusion and other reasons, specifically as follows:

1, atherosclerosis

after atherosclerosis, blood flow in the aorta slows down, may affect the normal blood supply of the brain, and then cause cerebral infarction.

2, cardiogenic embolism

emboli produced in the heart site, may fall off due to atrial flutter, atrial fibrillation and other reasons, and enter the brain with blood circulation to block cerebral vessels, thus causing cerebral infarction.

3, small artery occlusion intracranial part of the small artery occlusion

, part of the brain tissue blood supply interrupted, and necrosis, liquefaction, forming cerebral infarction.
