For brainstem thrombosis, if the thrombosis is considered to be small, the patient can be clinically cured if timely and correct treatment is given early. If the patient has a large thrombus, the general signs and symptoms are heavy, which may cause the patient’s death, and the patient can also stay with certain complications and sequelae. If thrombolytic therapy is used within six hours of the onset of the disease, the embolus can be dissolved and cerebral blood flow can be restored by hand, and some patients can be clinically cured. Some patients may also have sequelae due to the embolus not dissolving, which may also lead to cerebral hemorrhage and can cause death of the patient. If the patient is not treated with thrombolysis, the main treatment aim is brain protection and improvement of somatic signs and symptoms, and the patient may be left with certain sequelae or complications.
