The mortality rate of cerebral infarction is high, depending on the location and size of the infarction, and the overall acute mortality rate is about 5% to 15%. The overall acute mortality rate is about 5% to 15%. The severity of the disease is different, the prognosis is different, and the mortality rate is also different.
1. Higher fatality rate: Progressive cerebral infarction, especially large cerebral infarction, has a rapid onset and rapid progression, with impaired consciousness or even coma, local ischemia, cerebral nerve dysfunction, etc., which often leads to complete hemiparesis of one side of the limb.
Cranial CT and MRI examinations suggest the presence of a widespread low-density shadow in one cerebral hemisphere, which may be accompanied by focal hemorrhage and secondary cerebral edema. If the intracranial pressure continues to increase, it can lead to brain herniation, which is life-threatening and has a high mortality rate.
2. Lower fatality rate: for example, lacunar cerebral infarction is often due to the presence of hypertension and other underlying diseases, which induces some small arteries to become narrowed and blocked, thus causing hypoxia and ischemia, and ultimately degeneration and necrosis of brain tissues. Generally, there is no obvious consciousness disorder, but there may be ataxia, dysarthria and other conditions. After active treatment, the fatality rate is low, but it may recur.
When cerebral infarction occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
