Cerebral thrombosis is caused by the narrowing or occlusion of blood vessels due to the formation of thrombus from intimal lesions in cerebral arteries, which causes a series of neurological symptoms and signs due to ischemic necrosis of brain tissue in the corresponding blood supply area as a result of blocked blood flow. So, what clinical manifestations of cerebral thrombosis will there be? The following are the clinical symptoms of cerebral thrombosis: 1.Sudden onset: it often starts in one upper limb, and then the symptoms of neurological dysfunction progressively involve other parts of the limb within a few hours or one or two days. Most of them are not accompanied by headache, vomiting and other symptoms of intracranial hypertension: secondary cerebral edema occurring within a few days after occlusion of a larger artery can worsen the symptoms and lead to impaired consciousness, and severe cerebral edema can also cause the risk of fatal displacement of intracranial structures (brain herniation).

Middle cerebral artery and its deep penetrating branches: most susceptible to involvement, with contralateral hemiparesis (severe degree), hemianesthesia (loss of sensation), ipsilateral hemianopia, and aphasia when the dominant hemisphere (usually the left side) is involved, and aphasia when the non-dominant hemisphere is involved. 4. Internal carotid artery: It can cause ipsilateral blindness. Other symptoms are often difficult to distinguish from those that occur after occlusion of the middle cerebral artery and its deep penetrating branches. 5. Anterior cerebral artery: uncommon, one side may cause contralateral hemiparesis (heavy in lower limbs, light in upper limbs), strong grip reflex and urinary incontinence. Bilateral involvement may cause emotional indifference, blurred consciousness, occasional muteness and spastic paraplegia. 6. Posterior cerebral artery: ipsilateral hemianopia, contralateral hemianesthesia, spontaneous thalamic pain, or sudden involuntary hemianopsia; dyslexia can be seen when the dominant hemisphere is involved. 7. Vertebrobasilar artery: oculomotor paralysis, pupillary abnormalities, tetraplegia, difficulty in eating and swallowing, impaired consciousness and even death.
