View Larger A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or even death.

Definition. Ischemic penumbra refers to a rim of tissue lying just outside the core ischemic region (area most severely damaged by stroke or ischemic event). Within the core ischemic region, blood and oxygen flow is severely diminished, resulting in neuronal death.

Research leader Mayo Clinic doctors and researchers actively study TIA causes, risk factors, prevention, diagnostic tests and treatment options, and conduct clinical trials. Read about research in stroke and vascular disease, vascular biology, and neurology.

Central nervous system infarction occurs over a clinical spectrum: Ischemic stroke specifically refers to central nervous system infarction accompanied by overt symptoms, while silent infarction by definition causes no known symptoms. Stroke also broadly includes intracerebral hemorrhage and subarachnoid hemorrhage.

Ocular ischemic syndrome: Mid-peripheral intraretinal hemorrhages, retinal neovascularization. Preeclampsia: Intraretinal hemorrhages, Elschnig spots, with serous retinal detachment. They are seen bilaterally with varying intensity.

Ischemic heart disease is a dynamic process of atherosclerosis of the coronary arteries or functional alterations of coronary circulation that can be modified by lifestyle, pharmacological therapies, and revascularization. Such treatment may result in disease stabilization or regression.

If your stroke symptoms go away after a few minutes, you may have had a transient ischemic attack (TIA), also sometimes called a “mini-stroke.” Although brief, a TIA is a sign of a serious condition that will not go away without medical help. Unfortunately, because TIAs clear up, many people ignore them.

An ischemic stroke occurs when a blood clot keeps blood from flowing to your brain. The blood clot is often due to atherosclerosis, which is a buildup of fatty deposits on the inner lining of a.

A transient ischemic attack is a brief occurrence during which blood flow to the brain is temporarily cut off, usually by a blood clot, but sometimes by a narrowed carotid artery. This causes stroke-like symptoms for a brief time, until the blood clot breaks apart or dissolves.

A Volkmann ischaemic contracture refers to a complex and variable flexion deformity involving distal limbs (typically the wrist and fingers) resulting from fibrosis and contracture of flexor muscles. Fracture of hinge joint (elbow) or arm outcomes this contracture. It is associated with supracondylar fracture of the humerus classically 7.

Coronary artery disease, also called coronary heart disease or ischemic heart disease, is the most common type of heart disease, but there are many other conditions that affect the heart. Acute coronary syndrome is a term that includes heart attack and unstable angina.
