What is intracranial atheromatous disease?

What is intracranial atheromatous disease?

Intracranial atherosclerosis is the build up of a sticky substance called plaque in the arteries that supply the brain with blood, causing the narrowing and blockage of these vessels. It is part of the same systemic process that affects the heart or legs causing a heart attack or pain while walking.

What is intracranial vascular disease?

Intracranial vascular disease involves the arteries within the skull or at the base of the skull. Atherosclerosis, the hardening and narrowing of the walls of these vessels due to deposits of fats that form plaques within the arteries, is the most common cause of extracranial and intracranial vascular disease.

How is cerebral atherosclerosis diagnosed?

Computer tomography (CT) and magnetic resonance imaging (MRI) of the brain can help reveal the presence of cerebral arteriosclerosis before ischemic strokes, hemorrhagic strokes, or vascular dementia develop. Treatment for cerebral arteriosclerosis can include medications or surgery.

What is intracranial circulation?

With cerebral circulation, cerebral stands for “brain,” and circulation, refers to “blood flow.” So, cerebral circulation is the movement of blood through the vessels that supply the brain and surrounding structures.

How is intracranial stenosis treated?

Angioplasty / stenting can successful reduce the stenosis to less than 30% without complications in 60 to 80% of patients [3]. Cerebral artery bypass is a surgical procedure that reroutes the blood supply around the plaque-blocked area. This procedure requires making an opening in the skull, called a craniotomy.

Can MRI detect blocked arteries in brain?

“MR angiography, using a small quantity of MRI dye injected into a vein in the arm, can produce detailed images of the arteries supplying the brain and can detect even minor degrees of narrowing or blockage. It does not involve exposure to x-rays and is widely regarded as a very safe, painless test,” Dr. Nael said.

Does atherosclerosis affect brain?

When atherosclerosis narrows the arteries close to your brain, you may develop carotid artery disease, which can cause a transient ischemic attack (TIA) or stroke.

Can brain stenosis be reversed?

Angioplasty / stenting can successful reduce the stenosis to less than 30% without complications in 60 to 80% of patients [3]. Cerebral artery bypass is a surgical procedure that reroutes the blood supply around the plaque-blocked area.

Can atherosclerosis in the brain be reversed?

“Our discovery that early-stage atherosclerosis can regress completely, whereas later-stage atherosclerosis is resistant to treatment, suggests that individuals at increased CAD risk would benefit greatly from early prevention using lipid-lowering drugs like statins.”
