How long you can live with cerebrovascular blockage depends on which blood vessel is blocked and the severity of the blockage, and there is no clear time point in clinical practice. Cerebrovascular blockage refers to the poor blood flow in the cerebral vessels due to various reasons, which can be divided into cerebral thrombosis and cerebral embolism. The causes of cerebral thrombosis are atherosclerosis, arteritis and other rare causes; the sources of cerebral embolism emboli can be of cardiac origin, non-cardiac origin and unknown origin. If the blocked vessel is a large or important intracranial vessel and the blockage is severe, severe limb paralysis, sensory abnormalities, impaired consciousness, and even life-threatening may occur. If the blockage is a small intracranial artery, the infarct area is small, and the patient’s symptoms are mild, it is less likely to affect the survival period. In conclusion, different causes of cerebrovascular blockage and different degrees of blockage bring different prognosis to patients, but whenever possible, we should repeatedly emphasize the importance of early medical consultation and timely treatment.
