Cerebral infarction is also called ischemic stroke, which is called stroke or stroke in Chinese medicine. The disease is caused by various reasons that the blood supply of local brain tissue is blocked, which leads to ischemic and hypoxic necrosis of brain tissue, and then produces corresponding clinical manifestations of neurological dysfunction. Clinically, according to the different pathogenesis, cerebral infarction can be divided into cerebral thrombosis, cerebral embolism and lacunar infarction. Among them, cerebral thrombosis is a common type of cerebral infarction, accounting for about 60% of all cerebral infarction. The pathophysiological process of this disease is essentially the process of ischemic necrosis of local brain tissue on the basis of atherosclerosis. Clinically, because the cerebral artery has a certain degree of self-compensation function, the long-term formation of cerebral atherosclerotic plaque has no obvious clinical manifestations. In the examination of cerebral infarction, head CT is a convenient and commonly used imaging examination of brain structure. Ultra-early CT can find some subtle early ischemic changes, such as high density sign of middle cerebral artery, unclear boundary between gray matter and lenticular nucleus, disappearance of cerebral sulcus and so on. The standard MRI sequence can clearly show ischemic infarction, brain stem, cerebellar infarction and venous sinus thrombosis, but it is not sensitive to cerebral infarction within hours of onset.
If acute cerebral infarction occurs, thrombolytic drugs such as urokinase or alteplase should be used in time, and edaravone, an anti-free radical drug, should be used for treatment. At the same time, aspirin enteric-coated tablets, atorvastatin and other drugs need to be taken for a long time.
