Duke's experts identify and treat intracranial stenosis, which occurs when blood flow to the brain is restricted by narrowed arteries or plaque buildup (atherosclerosis) in the small twisting vessels deep within the brain. These blockages can greatly increase your risk of stroke.
Intracranial stenosis, also known as intracranial artery stenosis, is the narrowing of an artery in the brain, which can lead to a stroke. The narrowing is caused by a buildup and hardening of fatty deposits called plaque.
Atherosclerotic intracranial arterial stenosis is an important cause of stroke that is increasingly being treated with percutaneous transluminal angioplasty and stenting (PTAS) to prevent...
Symptomatic intracranial atherosclerotic stenosis (sICAS), typically defined as an ischemic stroke or transient ischemic attack associated with a proximal 50% to 99% stenosis of a relevant intracranial artery, is one of the most common causes of ischemic stroke in the world. 1 Non-ICAS strokes have a first-year recurrence rate of 5%, 2 which is ...
Intracranial stenosis is the severe narrowing of an artery within the skull. A blood vessel narrows when fatty deposits (plaque) build up inside the vessel, a condition known as atherosclerosis. Stenosis can restrict blood flow to areas of the brain, increasing the risk of stroke.
Intracranial atherosclerotic stenosis (ICAS) is one of the most frequent causes of stroke worldwide and confers one of the greatest risks of recurrent stroke compared with other causes of stroke. Asymptomatic ICAS is increasingly recognised as a risk factor for silent brain infarctions and dementia, magnifying the global burden of ICAS.
What is extracranial/intracranial vascular disease? Extracranial vascular disease refers to carotid or vertebral stenosis outside the skull. Intracranial vascular disease involves the arteries within the skull or at the base of the skull.
Intracranial atherosclerotic stenosis (ICAS) represents a more advanced stage of intracranial atherosclerotic disease, in which the vessel lumen has narrowed, in clinical practice usually 50–99% of the diameter, due to atherosclerotic lesions (Qureshi et al., 2009).
Intracranial stenosis (IS) refers to the narrowing or blockage of a blood vessel in the brain due to plaque or other substance building inside the artery wall.
When this happens in the brain, it's called cerebral vascular stenosis or intracranial vascular stenosis. Common causes of this condition are high blood pressure, diabetes, high cholesterol, heart disease, and more.
