Lung infarction. Lung infarction, death of one or more sections of lung tissue due to deprivation of an adequate blood supply. The section of dead tissue is called an infarct. The cessation or lessening of blood flow results ordinarily from an obstruction in a blood vessel that serves the lung.
Not to be confused with Infraction. Infarction is tissue death (necrosis) due to inadequate blood supply to the affected area. It may be caused by artery blockages, rupture, mechanical compression or vasoconstriction. The resulting lesion is referred to as an infarct (from the Latin infarctus, stuffed into). Myocardial infarction is the partial death of heart tissue commonly known as a heart attack.
