Hemorrhagic infarct

Recent hemorrhagic infarcts.

Hemorrhagic infarcts are infarcts commonly caused by occlusion of veins, with red blood cells entering the area of the infarct, or an artery occlusion of an organ with collaterals or dual circulation. This is commonly seen in brain^[1] , lungs, liver and the GI tract, areas referred to as having "loose tissue," or dual circulation. Loose-textured tissue allows red blood cells released from damaged vessles to diffuse through the necrotic tissue. White infarcts can become hemorrhagic with reperfusion. Compare to Anemic infarct. Hemorrhagic infarction is also associated with testicular torsion.^[2]
