A catheter may be passed into the brain vasculature to close off or dilate blood vessels, avoiding invasive surgical procedures. Aspiration by stereotactic surgery or endoscopic drainage may be used in basal ganglia hemorrhages, although successful reports are limited. A craniectomy holds promise of reduced mortality, but the effects of long‐term neurological outcome remain controversial. Prognosis About 8 to 33 of those with intracranial haemorrhage have neurological deterioration within the first 24 hours of hospital admission, where a large proportion of them happens within 6 to 12 hours. Rate of haematoma expansion, perihaematoma odema volume and the presence of fever can affect the chances of getting neurological complications. The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the injury occurs in the brain stem. Intraparenchymal bleeds within the medulla oblongata are almost always fatal, because they cause damage to cranial nerve X, the vagus nerve, which plays an important role in blood circulation and breathing. This kind of hemorrhage can also occur in the cortex or subcortical areas, usually in the frontal or temporal lobes when due to head injury, and sometimes in the cerebellum. Larger volumes of hematoma at hospital admission as well as greater expansion of the hematoma on subsequent evaluation (usually occurring within 6 hours of symptom onset) are associated with a worse prognosis. Perihematomal edema, or secondary edema surrounding the hematoma, is associated with secondary brain injury, worsening neurological function and is associated with poor outcomes. Intraventricular hemorrhage, or bleeding into the ventricles of the brain, which may occur in 30-50% of patients, is also associated with long term disability and a poor prognosis. Brain herniation is associated with poor prognoses. For spontaneous intracerebral hemorrhage seen on CT scan, the death rate (mortality) is 34–50% by 30 days after the injury, and half of the deaths occur in the first 2 days. Even though the majority of deaths occur in the first few days after ICH, survivors have a long-term excess mortality rate of 27% compared to the general population. Of those who survive an intracerebral hemorrhage, 12–39% are independent with regard to self-care; others are disabled to varying degrees and require supportive care. Epidemiology The incidence of intracerebral hemorrhage is estimated at 24.6 cases per 100,000 person years with the incidence rate being similar in men and women. The incidence is much higher in the elderly, especially those
