Cerebral infarction collateral circulation is established mainly through: the Willis ring at the base of the brain, the ophthalmic artery, the anastomotic vessels of the lateral branches of the molluscum contagiosum, as well as the anastomosis of the branches of other intracranial and extracranial arteries and the newly generated blood vessels induced by cerebral ischemia.
Cerebral collateral circulation refers to when the blood supplying artery is severely occluded, the blood flow can reach the ischemic tissue area through other blood vessels, so that the ischemic tissues regain irrigation, which is one of the cerebral circulatory compensatory mechanisms; cerebral collateral circulation can be divided into three levels:
1. Primary collateral circulation: Willis ring at the base of the brain, when cerebral infarction occurs, this circulation is the most rapid and the most important collateral circulation compensation pathway, the integrity of the Willis ring of each person varies, depending on the innate structure.
2. Secondary collateral circulation: anastomosis of the ophthalmic artery, the lateral branch of the molluscum contagiosum, and other branches of the intracranial and extracranial arteries; this circulation requires a certain amount of time to compensate for the occurrence of cerebral infarction.
3. Tertiary collateral circulation: when newly generated blood vessels are induced after cerebral infarction, the establishment of this circulation takes several days to complete; synthetic racemic n-butylphthalide, such as butylphthalide, is often used in clinics to promote the establishment of collateral circulation.
If you feel unwell, you should go to the hospital in time, under the guidance of the physician, to identify the cause and then give targeted treatment.
