What is the meaning of Nonhemorrhagic?
Medical Definition of nonhemorrhagic : not causing or associated with hemorrhage nonhemorrhagic shock.
Why are some infarcts red?
Red (haemorrhagic) infarcts occur due to venous occlusion or embolism in organs with a dual blood supply. Below is a picture of an intestinal infarct (note some normal loops of bowel). It is red in colour because the small intestine has a dual blood supply.
Are brain infarcts red or white?
Infarcts. True infarcts are villous regions that have lost their maternal blood supply. They are firmer than adjacent tissue and granular from remaining villous ghosts. They age from red to yellow and white.

What are red and white infarcts?
Anemic infarcts (also called white infarcts or pale infarcts) are white or pale infarcts caused by arterial occlusions, and are usually seen in the heart, kidney and spleen. These are referred to as “white” because of the lack of hemorrhaging and limited red blood cells accumulation, (compare to Hemorrhagic infarct).
What is the difference between ischemia and infarction?
Both terms, ischemia and infarction, are used here. Ischemia denotes diminished volume of perfusion, while infarction is the cellular response to lack of perfusion. Some of the changes discussed here are the result of ischemia such as those involving myocardial substrate extraction.
What is a white infarct?
What is white matter infarction?
Abstract. White matter stroke (WMS) is a debilitating disorder, which is characterized by the formation of ischemic lesions along subcortical white matter tracts of the central nervous system. Initial infarction during the early stages of the disease is often asymptomatic and is thus considered a form of silent stroke.
