Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots ( thrombosis ). [ 2] A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
Intraventricular hemorrhage. Intraventricular hemorrhage (IVH), also known asintraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke .
A cerebral AVM is an abnormal anastomosis (connection) between the arteries and veins in the human brain and are most commonly of prenatal origin. [ 10] In a normal brain, oxygen-enriched blood from the heart travels in sequence through smaller blood vessels going from arteries, to arterioles and then capillaries. [ 10] Oxygen is removed in the ...
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply. Severe increases in intracranial pressure (ICP) can cause brain herniation, in which parts of the brain are squeezed past structures ...
Brainstem stroke syndrome. A brainstem stroke syndrome falls under the broader category of stroke syndromes, or specific symptoms caused by vascular injury to an area of brain (for example, the lacunar syndromes ). As the brainstem contains numerous cranial nuclei and white matter tracts, a stroke in this area can have a number of unique ...
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [ 2] The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and ...
