What is cerebral arterial occlusion?

The arterial occlusion impedes perfusion of oxygenated blood to the brain parenchyma, resulting in an ischemic stroke causing cerebral edema and brain parenchyma tissue necrosis. As a general rule, a proximal occlusion will cause damage to a large surface area and be devastating.

How is a blocked artery in the brain treated?

If the narrowing of the artery is severe, and doesn’t respond to medications or is greater than a 50% blockage, more invasive treatment may be needed. The main options for treating narrowing of the arteries in the brain are: Angioplasty to reopen the artery with possible stenting. Cerebral artery bypass surgery.

Can you live with blocked artery?

Today, we have more treatment options. We can sometimes go around the blockage or work backward through the heart. We’re now seeing success rates of 90% to 95%. If you are told that you have an artery that is 100% blocked, it’s important to know that it can be treated.

How serious is a blockage in the brain?

The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.

Can cerebral stenosis be cured?

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 a blocked carotid artery cause a stroke?

If the narrowing of the carotid arteries becomes severe enough that blood flow is blocked, it can cause a stroke. If a piece of plaque breaks off it can also block blood flow to the brain. This too can cause a stroke.

How does anterior cerebral artery occlusion affect the leg?

If the lesion is in the dominant hemisphere then dysphasia may be expected whereas a non-dominant lesion will be accompanied by neglect or perceptual disturbance. Anterior cerebral artery occlusion leads to contralateral hemiparesis affecting the leg more severely than the arm.

How does cerebrovascular occlusive disease affect the brain?

Cerebrovascular Occlusive Disease. Arteries carry oxygen-rich blood away from the heart to the head and body. There are two carotid arteries (one on each side of the neck) that supply blood to the brain. Carotid arteries may develop atherosclerosis, the buildup of fat and cholesterol deposits, called plaque, on the inside of the arteries.

Is there radiological evidence of other cerebral arteries?

There was no radiological or autopsy evidence of involvement of the other cerebral arteries or their territories.

Can a posterior cerebral artery cause contralateral hemiplegia?

Conclusions: The patient provides further evidence that occlusion of the posterior cerebral artery just distal to its junction with the posterior communicating artery may produce contralateral hemiplegia without oculomotor nerve nucleus involvement.
