Thrombolytic therapy can be performed for previous cerebral hemorrhage, but it must be judged according to the actual situation. If the cerebral hemorrhage is 6 months ago and the condition is stable, and the hemorrhagic foci are clearly softened, and there is no acute hemorrhage, thrombolysis can be performed at this time. If the interval is more stable than 3 years, thrombolysis is not necessarily not available if there is a previous cerebral hemorrhage. If the time since the previous cerebral hemorrhage is relatively short and there is a very obvious fresh bleeding foci, thrombolysis should not be performed at this time, which is a contraindication to thrombolysis. If there is bleeding in other parts of the body, thrombolysis should not be performed either, which will bring more adverse damage to the patient, so the corresponding medical history and examination should be completed before thrombolysis.
