Infarction Definition = ischemic necrosis of tissue due to occlusion
of arterial ( in most of cases) or venous ( in gonads) circulation
Most common cause of Death in USA Most commonly in 99% of cases = arterial occlusion
by thrombo-embolism Rarely venous drainage problem ( in Testis, Ovary) Very rarely vasospasm
Morphological Types Red & White Wedge shaped with base at the periphery of organ
Final outcome Coagulative necrosis ( Liquefactive in Brain)
Septic infarction = in pts. With infective Endocarditis

Infarctions- Types
Red (Hemorrhagic) Venous occlusion In loose tissues
(lung) Organs with dual
blood supply (Lungs, Liver)
Previously congested organs ( nutmeg liver)
Re- perfused tissues

White (Anemic)• Arterial occlusion• Solid organs• End arterial supply
( Kidney, Spleen, Retina, Heart)
