Patients with cerebral infarction can be treated with embolization in the acute phase according to the vascular obstruction, and if embolization fails, embolization can also be pulled. If the onset of acute cerebral infarction is within 4.5 hours, intravenous thrombolysis with alteplase can be given; if severe stenosis of the responsible vessel exists within 24 hours of onset then mechanical embolization can be considered. It cannot be performed in patients with sequelae of cerebral thrombosis because the thrombus has already formed, and some patients have formed cerebral softening foci. For the treatment of cerebral thrombosis embolization, it is mainly for the acute phase of cerebral infarction. If the patient fails to retrieve the embolus, the subsequent drug treatment of anti-platelet aggregation, improving circulation and activating blood circulation should also be given. Try to save the patient’s ischemic semidark zone, promote the opening of collateral circulation, and reduce the patient’s neurological deficit symptoms.
