A brain hemorrhage of 15 ml usually takes 2 to 3 months to be completely absorbed. For brain hemorrhage 15ml, its treatment depends mainly on the location of the hemorrhage. If the brain hemorrhage 15ml is located in the cerebral cortex, thalamus, basal ganglia, etc., conservative treatment is the main treatment. Conservative treatment is mainly based on symptomatic treatment such as controlling and stabilizing blood pressure, dynamic review of head CT, turning, back tapping, and nebulization. Early rehabilitation is required if there is late limb dysfunction. If the cerebral hemorrhage of 15 ml is located in the cerebellar region, surgical treatment is required. Because the cerebellum is close to the brainstem, its bleeding of 15 ml can easily compress the brainstem and cause respiratory and cardiac arrest. Therefore, surgical treatment is needed. If the brain hemorrhage of 15 ml is located in the brainstem area, it makes little sense to use both conservative and surgical therapies. This is because brainstem hemorrhage, with a bleeding volume greater than 10 ml, has a mortality rate close to 100%. Overall, brain hemorrhage of 15 ml, its complete absorption takes 2 to 3 months.
