Definitions
Hemorrhagic stroke: A stroke caused by the rupture of a blood vessel within the brain tissue, subarachnoid space or intraventricular space.
Intracranial hemorrhage includes bleeding within the cranial vault and encompasses intraventricular, intraparenchymal, subarachnoid, subdural and epidural hemorrhage.
Spontaneous, nontraumatic intracerebral hemorrhage is bleeding within the brain parenchyma without obvious systemic, neoplastic, traumatic, or macrovascular etiology. This stroke subtype accounts for about 10-15%a of all strokes and a disproportionately higher number of stroke related deaths. ICH are often categorized according to their location within the brain: lobar, deep, cerebellar, and brainstem.
Hemorrhagic infarct: Hemorrhagic infarct is defined as a hemorrhagic transformation into an area of arterial ischemic infarction or venous thrombosis associated tissue congestion.
