Is a cerebral artery occlusion a stroke?

The two basic types of stroke are ischemic and hemorrhagic. In ischemic stroke, occlusion of a cerebral artery causes damage to the brain tissue dependent on blood supply from the affected vessel. In hemorrhagic stroke, a cerebral artery leaks blood, which damages adjacent brain tissue.

What causes occlusion of cerebral artery?

The most common cause of MCA occlusion is embolism, and sudden occlusion of the proximal MCA by an embolus is one of the most frequent causes of major stroke. In addition, emboli, especially those from the heart, frequently undergo lysis, and no residual vascular obstruction is found in more than half of the patients.

What does cerebral infarction mean?

Also called ischemic stroke, a cerebral infarction occurs as a result of disrupted blood flow to the brain due to problems with the blood vessels that supply it. A lack of adequate blood supply to brain cells deprives them of oxygen and vital nutrients which can cause parts of the brain to die off.

Is cerebral infarction and stroke the same thing?

Doctor’s response. A cerebral infarction (also known as a stroke) refers to damage to tissues in the brain due to a loss of oxygen to the area. The mention of “arteriosclerotic cerebrovascular disease” refers to arteriosclerosis, or “hardening of the arteries” that supply oxygen-containing blood to the brain.

What is the typical outcome of cerebral infarction?

Infarctions will result in weakness and loss of sensation on the opposite side of the body. Physical examination of the head area will reveal abnormal pupil dilation, light reaction and lack of eye movement on opposite side. If the infarction occurs on the left side brain, speech will be slurred.

Is cerebral infarction fatal?

ALTHOUGH CEREBRAL INFARCTION is a common cause of death in the United States, little is known about the actual mechanism of deaths during the immediate postinfarction period. Some authors have implicated acute brain swelling as a major con- tributor to death from cerebral infarction.

What is a cerebral artery occlusion?

Overview. When an artery inside the skull becomes blocked by plaque or disease, it is called cerebral artery stenosis. Arteries anywhere in the body can become blocked. For example, carotid artery stenosis is a narrowing of the large artery in the neck, the carotid, that supplies oxygen-rich blood to the brain.

What is the treatment of cerebral infarction?

Emergency IV medication. An IV injection of recombinant tissue plasminogen activator (TPA) — also called alteplase (Activase) or tenecteplase (TNKase) — is the gold standard treatment for ischemic stroke. An injection of TPA is usually given through a vein in the arm within the first three hours.
