Cerebral infarction should be in neurology, cerebral infarction is a common and frequent disease in neurology, it is an acute ischemic cerebrovascular disease, which refers to the obstruction of cerebral blood circulation due to various reasons, thus causing ischemic and hypoxic necrosis of brain tissues, and there are various causes of the disease, the common cause of the disease is atherosclerosis of brain arteries, followed by hypertension, diabetes mellitus, and hyperlipidemia and so on. For some patients with cerebral embolism, it can be caused by various emboli in the blood falling off and blocking the cerebral arteries, such as the common cardiac thrombus attached to the wall, atherosclerotic plaques, and in some patients, it is due to the improper use of blood pressure-lowering medications, shock caused by various reasons, and cardiac surgery combined with low blood pressure and severe dehydration, all of which can be caused. The treatment of cerebral infarction is mainly to give conservative treatment, if the patient is suitable for thrombolysis, give thrombolysis treatment, not suitable for thrombolysis, should be given as early as possible anti-platelet aggregation as well as neuroprotective therapy. For patients with large cerebral hemispheric cerebral infarction, craniotomy and decompression surgery can be performed to remove part of the brain tissue to reduce intracranial pressure.
