Cerebrovascular blockage is a condition in which the blood vessels supplying brain tissue become obstructed, resulting in ischemia of brain tissue and even necrosis of brain cells. Complete blockage of cerebral blood vessels often results in necrosis of brain tissue in the supply area, also known as “cerebral infarction”, which is divided into cerebral embolism and cerebral thrombosis. Cerebral thrombosis is supposed to have the highest clinical incidence. It is caused by arteriosclerosis, arteritis, or some blood disorders that lead to thrombosis of intracranial vessels. Cerebral embolism, on the other hand, is a blockage of cerebral blood vessels formed when tissue shed from other parts of the body becomes an embolus and runs through the bloodstream into the skull. After the blockage of cerebral vessels, patients will have corresponding symptoms, such as blockage to the motor area will lead to limb dysfunction and hemiparesis; if blockage to the speech center, patients will have aphasia (motor, sensory aphasia, naming aphasia); if blockage to the visual nerve, patients will have visual impairment; if blockage to the middle cerebral artery by cerebral thrombosis, patients will have large cerebral infarction and will have If the cerebral thrombus blocks the middle cerebral artery, the patient will have a large cerebral infarction, which will result in impaired consciousness and respiratory and circulatory failure, and can lead to death in serious cases. If the diagnosis of cerebrovascular blockage is confirmed, active neurological treatment is required. Sometimes small focal cerebral infarcts are also important to pay attention to because small cerebral infarcts may progress to large cerebral infarcts. It is also crucial to treat the causes of cerebrovascular blockage, such as treatment of underlying diseases of hypertension, diabetes, atherosclerosis hyperlipidemia, etc.
