renal infarctionNephrology Death of renal tissue, usually caused by renal artery sternosis
1. the formation of an infarct.
2. an infarct.
see myocardial infarction (below) and also myocardial infarction.
an ischemic condition of the brain, causing a persistent focal neurological deficit in the area affected.
an aseptic fever caused by liberation of pyrogens from damaged tissue.
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.
gross necrosis of the myocardium, due to interruption of the blood supply to the area. See also myocardial infarction.
localized necrosis of lung tissue, due to obstruction of the arterial blood supply.
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.
usually hemorrhagic; may be difficult to differentiate from subcapsular hematoma.
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.
