infarct

[′in‚färkt] (medicine) Localized death of tissue that is caused by obstructed inflow of arterial blood. Also known as infarction.

Infarct

a focus of organ or tissue necrosis resulting from an interruption of the blood supply to the area. The direct causes of infarcts are thrombosis, embolism, or spasm of the arteries feeding this tissue. Hypoxia is a decisive factor in the development of the tissue changes associated with an infarct.

There are three types: white, or ischemic, infarct, which is a zone of necrosis lacking in blood; red, or hemorrhagic, infarct, in which the zone of necrosis is saturated with excessive blood; and ischemic infarct with a hemorrhagic zone. The first and third types of infarct are generally formed in the heart, kidneys, and spleen, and the second in the lungs and intestine. An infarct may be conical (kidney, lungs) or irregular (heart, brain) in shape. Its consistency varies with the nature of the necrosis, which may be dry (myocardial infarct) or moist (cerebral infarct).

Infarcts cause profound changes in the organs affected. The dead areas are resorbed or organized, resulting in the formation of a cyst (in the brain) or a scar (in the heart muscle), or they may suppurate and liquefy (septic infarct). The size, location, and properties of an infarct determine whether the affected organ becomes weakened or loses its functions.

infarct

[in´fahrkt] a localized area of ischemic necrosis produced by anoxia following occlusion of the arterial supply or the venous drainage of the tissue, organ, or part.anemic infarct one due to sudden interruption of arterial circulation to the area.hemorrhagic infarct one that is red owing to oozing of erythrocytes into the injured area.

(in'fahrkt) An area of necrosis resulting from a sudden insufficiency of arterial or venous blood supply.
Synonym(s): infarction (2) .

infarct

A volume of dead tissue lying within living tissue, the death being caused by local loss of blood supply. Infarcted tissue swells and becomes firm, and blood vessels around an infarct widen. Plasma and blood may pass into the infarct, increasing the swelling. Later the infarct becomes pale and shrinks and soon it is replaced by fibrous tissue and is converted into a scar which is usually at least as strong as the original tissue. Function is, of course, lost.

Infarct
