This chapter reviews the pathology, epidemiology, treatment and management of Intracerebral hemorrhage and subarachnoid hemorrhage (SAH). Hypertensive intracerebral hemorrhages typically occur in territories perfused by deep perforating arteries coming off the basal cerebral arteries. The advent in early use of CT imaging, however, has documented expansion of intracerebral hemorrhage in almost 40% of the cases. The role of surgery for supratentorial hemorrhages has been extensively evaluated in the management of intracerebral hemorrhage, with most of these studies showing no benefit of surgical evacuation of the hematoma. There are approximately 25-30,000 patients a year with SAH. The initial management strategy for the patient after SAH is to stabilize the patient until the cerebral aneurysm can be identified and secured. Interventional procedures may be needed to open constricted cerebral blood vessels if medical maneuvers are insufficient to improve or prevent the onset of neurological deficits due to vasospasm.
