Cerebral infarction is more effective after thrombolysis. After most clinical experiments, it is proved to be a treatment with good therapeutic effect, but note that the adaptation conditions are very strict. First, the patient’s onset to the hospital is to be within six hours, in the acute phase, and thrombolysis cannot be done in the chronic phase. Furthermore, the patient should not have bleeding disorders or undergo large-scale surgery within three months in the cranium or other parts of the body, so that thrombolysis can easily cause bleeding disorders in the brain. The patient’s blood pressure should be controlled smoothly, otherwise the tendency of cerebral hemorrhage is likely to occur if the blood pressure rises again after the operation, so the adaptation conditions are very demanding. Among the clinical conditions, many complications originate from the patient’s bleeding, that is, cerebral infarction combined with bleeding, which is risky, and if thrombolysis is suitable, timely thrombolytic treatment should be performed so that the effect is better.
