renal infarcts are the result of embolized thrombi that lodge in renal
Vascular occlusion by embolized thrombi causes
infarctive, coagulative type necrosis.,
The epidemiology is
that of the primary disease process affecting the heart, i.e,
atherosclerotic cardiovascular disease, infectious endocarditis.
|General Gross Description|
On cut section, renal infarcts are
triangular with the base at the cortical surface and the apex
pointing towards the medulla and the occluded artery.
A day or so after
occlusion, the infarct appears pale compared to adjacent parenchyma.
resolved infarcts on cut section show a V shape absence of renal
|General Microscopic Description|
Recent infarcts show coagulative necrosis where the native
renal architecture is discernible but the tissue is necrotic.
Heal by scarring.
