Which of the following is not a feature of red infarction?
Ans. C: Occurs in solid organs Red infarctions (hemorrhagic infarcts), generally affect the lungs or other loose organs like testis, ovary, small intestines The occlusion consists more of red blood cells and fibrin strands. Characteristics of red infarcts include: occlusion of a vein; loose tissues that allow blood to collect in the infarcted zone; tissues with a dual circulatory system (lung, small intestines); tissues previously congested from sluggish venous outflow; Reperfusion (injury) of previously ischemic tissue that is associated with reperfusion-related diseases such(Myocardial infarction, stroke (cerebral infarction), shock-resuscitation, replantation surgery, frostbite, burns and organ transplantation)
