infarction /in·farc·tion/ (in-fahrk´shun)

1. the formation of an infarct.

2. infarct.

---

acute myocardial infarction  (AMI) that occurring during the period when circulation to a region of the heart is obstructed and necrosis is occurring.

cardiac infarction  myocardial i.

cerebral infarction  an ischemic condition of the brain, causing a persistent focal neurologic deficit in the area affected.

mesenteric infarction  coagulation necrosis of the intestines due to a decrease in blood flow in the mesenteric vasculature.

migrainous infarction  a focal neurologic defect that constituted part of a migrainous aura but that has persisted for a long period and may be permanent.

myocardial infarction  (MI) gross necrosis of the myocardium, due to interruption of the blood supply to the area.

Myocardial infarction shown in cross-section of heart (ventricles only).

non–Q wave infarction  myocardial infarction not characterized by abnormal Q waves.

pulmonary infarction  localized necrosis of lung tissue, due to obstruction of the arterial blood supply.

Q wave infarction  myocardial infarction characterized by Q waves that are abnormal either in character or number or both.

silent myocardial infarction  myocardial infarction occurring without pain or other symptoms; often detected only by electrographic or postmortem examination.

watershed infarction  cerebral infarction in a watershed area during a time of prolonged systemic hypotension.

cardiac infarction

see myocardial infarction (below) and also myocardial infarction.

cerebral infarction

an ischemic condition of the brain, causing a persistent focal neurological deficit in the area affected.

infarction fever

an aseptic fever caused by liberation of pyrogens from damaged tissue.

intestinal infarction

a common occurrence in horses due to occlusion of arteries by larvae of Strongylus vulgaris. Sections of intestine, sometimes very large ones, become devitalized leading to peritonitis and death.

May also result from torsion or strangulation. See also thromboembolic colic.

myocardial infarction

gross necrosis of the myocardium, due to interruption of the blood supply to the area. See also myocardial infarction.

pulmonary infarction

localized necrosis of lung tissue, due to obstruction of the arterial blood supply.

renal infarction

is usually conical, anemic and multiple and may heal leaving a narrow scar. It is usually clinically inapparent unless the obstructing material is infected. This leads to the development of renal abscess or embolic nephritis, also usually without clinical signs unless the abscesses are large or numerous.

spinal cord infarction

caused sometimes by fibrocartilaginous emboli of prolapsed disk material, causing sudden loss of function of large sections of the spinal cord, leading to flaccid paralysis of the hindlimbs or of all four, depending on the site of the infarct.

splenic infarction

usually hemorrhagic; may be difficult to differentiate from subcapsular hematoma.

venous infarction

a thrombus in a vein may cause infarction, e.g. in the thigh muscles of downer cow, recumbent for long periods, or in the gastric mucosa of pigs, where it is a common finding in acute septicemia.
