Hemorrhagic Stroke results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are subarachnoid hemorrhage and intracerebral hemorrhage. Subarachnoid hemorrhage (SAH) occurs when a blood vessel on the surface of the brain ruptures and bleeds into the space between the brain and the skull. Intracerebral hemorrhage (ICH) occurs when a blood vessel bleeds into the tissue deep within the brain.
