Infarcts are areas of ischemic, usually coagulative, necrosis caused by
occlusion of arterial supply or less commonly venous drainage.Infarcts are most
commonly caused by formation of occlusive arterial thrombi, or embolization of
arterial or venous thrombi.Infarcts caused by venous occlusion, or in loose
tissues with dual blood supply, are typically hemorrhagic (red) whereas those
caused by arterial occlusion in compact tissues are pale (white) in color
An infarct is an area of ischemic necrosis caused by occlusion of either the
arterial supply or the venous drainage in a particular tissue. Tissue infarction
is a common and extremely important cause of clinical illness. More than half of
all deaths in the United States are caused by cardiovascular disease, and most
of these are attributable to myocardial or cerebral infarction. Pulmonary
infarction is a common complication in several clinical settings, bowel
infarction is frequently fatal, and ischemic necrosis of the extremities
(gangrene) is a serious problem in the diabetic population.
