For patients with heavy bleeding and critical conditions, craniotomy is needed to save their lives. However, craniotomy for cerebral hemorrhage itself carries certain risks, which may cause re-bleeding, damage to the functional brain area, intracranial infection and so on. 1. Re-bleeding: During the operation, patients may have the possibility of re-bleeding in the operated area. If the bleeding is too large and the bleeding is not stopped in time, it may endanger the patient’s life. 2. Injury to functional brain area: If the blood vessels of the cranium and brain are injured during surgery, it will cause loss of the function that governs the brain area and lead to sequelae. 3. Intracranial infection: craniotomy for cerebral hemorrhage carries a certain risk of intracranial infection. Craniotomy for cerebral hemorrhage is a risky procedure and requires a neurosurgeon to carefully evaluate the pros and cons of the surgery and choose an appropriate treatment plan.
