Cerebral embolism is difficult to be completely cured, the blood vessel being embolized can lead to ischemia and necrosis of local brain tissues, which in turn leaves sequelae such as limb movement disorder and limb sensory disorder, and cerebral embolism is easy to recur. Cerebral embolism is a disease in which various emboli in the blood enter the cerebral arteries along with the blood flow and block the blood vessels, causing ischemia and necrosis of the brain tissues, and the thrombus attached to the wall of the heart, the plaques of atherosclerosis, fat, air, etc. can embolize the cerebral blood vessels, leading to the occurrence of cerebral embolism. The brain tissue at the site of embolism can be ischemic and necrotic, which leads to brain dysfunction and a series of sequelae such as limb movement disorders, limb sensory disorders, facial paralysis, numbness of the mouth and tongue, dizziness, ataxia, speech disorders, diplopia, etc. If the necrosis of brain tissue caused by cerebral embolism is small in scope and the treatment is timely, the sequelae can be alleviated to a certain extent. If the necrosis is large in scope and the treatment is not timely, it can lead to serious sequelae and even affect life. It is recommended to seek timely medical treatment for cerebral embolism.
