How long can one live after craniotomy for cerebral hemorrhage can’t be generalized, it mainly depends on the amount of bleeding and bleeding site of cerebral hemorrhage, minor cases don’t affect life expectancy, while serious cases can die within a few hours. 1. Bleeding volume: For patients with a small amount of brain hemorrhage and slight destruction of brain tissues, after timely craniotomy to remove intracerebral hematoma and postoperative treatment to reduce intracranial pressure by using mannitol and other dehydration, usually patients can recover in about 1 month, and after recovery, patients can survive for a long time like normal people. For patients with large amount of cerebral hemorrhage and severe destruction of the surrounding brain tissue, even with systematic treatment, the prognosis is poorer, and most patients can have serious sequelae, which affects their life expectancy to a certain extent. However, due to the large individual differences, it is difficult to specify how long the patient can live. 2. Bleeding site: For example, bleeding in special areas, such as brain stem hemorrhage, often affects the respiratory and circulatory centers, and patients can die in a short time. Even if some patients save their lives through craniotomy, their quality of life and survival time will be greatly affected. Therefore, patients with cerebral hemorrhage need to go to the hospital in time to save their lives, and must not be negligent so as not to delay their condition.
