What is the meaning of embolic stroke?

Embolic strokes are usually caused by a blood clot that forms elsewhere in the body (embolus) and travels through the bloodstream to the brain. Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs.

What type of stroke is an embolic stroke?

An embolic stroke occurs when a blood clot that forms elsewhere in the body breaks loose and travels to the brain via the bloodstream. When the clot lodges in an artery and blocks the flow of blood, this causes a stroke. This is a type of ischemic stroke.

What causes cardioembolic stroke?

The leading cause of cardioembolic stroke is atrial fibrillation (paroxysmal and chronic atrial fibrillation), especially in elderly individuals.

What causes brain embolism?

A brain embolism happens when an artery that carries oxygen-rich blood and nutrients to the brain becomes blocked. Blockages can occur when a blood clot from elsewhere in the body travels through the bloodstream and lodges in an artery inside the brain, or one that feeds into the brain.

Which artery is most often affected in embolic stroke?

Owing to their large size, cardiac emboli flow to the intracranial vessels in most cases and cause massive, superficial, single large striatocapsular or multiple infarcts in the middle cerebral artery.

What is the meaning of embolic?

Medical Definition of embolic 1 : of or relating to an embolus or embolism embolic occlusion of a middle cerebral artery with cholesterol material— D. R. Gress & J. H. Eichhorn. 2 : of, relating to, or produced by emboly.

How do you know if your having cardioembolic stroke?

Certain clinical features are suggestive of cardioembolic infarction, including sudden onset to maximal deficit, decreased level of consciousness at onset, Wernicke’s aphasia or global aphasia without hemiparesis, a Valsalva manoeuvre at the time of stroke onset, and co-occurrence of cerebral and systemic emboli.

What causes an embolism?

Most embolisms happen to people who have risk factors for blood clot formation, such as smoking and heart disease. Other risk factors for other types of emboli include high blood pressure, atherosclerosis (buildup of fatty plaque in the blood vessels), high cholesterol, and obesity.
