The incidence of secondary cerebral hemorrhage after thrombolysis for cerebral infarction is about 8%, but the consequences are serious, including the following: 1. If the amount of bleeding is relatively small, it can be treated conservatively with medication, such as intravenous infusion of cold precipitates to promote coagulation. Alternatively, fresh plasma can be transfused. Plasma has many coagulation factors, which can replenish the coagulation factors consumed during thrombolysis. In addition, plasminogen complex can be transfused to promote coagulation; 2. If CT examination reveals a large amount of bleeding and the patient’s altered state of consciousness, conservative treatment may be ineffective and craniotomy is needed to deal with the hematoma, which will be removed after craniotomy. If the intracranial pressure is very high, debridement can be performed. In this process, the patient may experience respiratory cardiac arrest, but the problem of outward expansion is not serious and does not affect the quality of survival of the patient.
