cerebral vascular dysfunction due to bleeding in the brain.
Caused by rupture of a blood vessel or aneurysm. Hypertension greatly increases the risk of hemorrhagic stroke especially in the thinner-walled vessels. An embolic stroke can also have a hemorrhagic component if the embolus blocks the vessel long enough to kill brain tissue and then breaks up, permitting re-perfusion of the now dead tissue.
Occurs when an artery in the brain tears or bursts, causing blood to spill out.
Interruption of the blood supply to an area of the brain caused by a break or rupture of a blood vessel in the brain. About 20% of strokes occur from hemorrhage.
stroke caused by the rupture of a blood vessel in the brain
a rare type of stroke characterized by severe bleeding in the brain
a rupture in the brain which causes bleeding
Rupture of a blood vessel in or near the brain. This type of stroke accounts for 20% of all strokes that occur. There are two types of hemorrhagic stroke: subarachnoid hemorrhage, which occurs when a blood vessel on the surface of the brain ruptures and bleeds into the space between the brain and skull; and intracerebral hemorrhage, which occurs when a blood vessel bleeds into the cerebrum, the main portion of the brain.
A stroke caused by a ruptured blood vessel and characterized by bleeding within or surrounding the brain. Subarachnoid hemorrhage from a ruptured cerebral aneurysm can lead to a hemorrhagic stroke.
a stroke caused by a ruptured blood vessel and characterized by bleeding within the brain, or bleeding into the space between the brain and the skull. Hemorrhagic strokes account for 17% of all strokes and are more devastating than the ischemic type.
A disorder involving bleeding within ischemic brain tissue. Hemorrhagic stroke occurs when blood vessels that are damaged or dead from lack of blood supply (infarcted), located within an area of infarcted brain tissue, rupture and transform an "ischemic" stroke into a hemorrhagic stroke. Ischemia is inadequate tissue oxygenation caused by reduced blood flow; infarction is tissue death resulting from ischemia. Bleeding irritates the brain tissues, causing swelling (cerebral edema). Blood collects into a mass (hematoma). Both swelling and hematoma will compress and displace brain tissue.
A stroke resulting from the rupture of a blood vessel in the brain.
stroke caused by bleeding out of one of the major arteries leading to the brain.
Sudden bleeding into or around the brain.
A stroke that occurs when a blood vessel ruptures in or near the brain.
A stroke that results from the bursting of a blood vessel that bleeds into the brain.
