图示：脾切面的两个大梗死灶（凝固性坏死）。梗死的原因通常是供血不足，因此梗死灶位于相应动脉分支的供血区域。因此梗死灶的形状常为底朝向器官被膜的楔形。
Two large infarctions (areas of coagulative necrosis) are seen in this sectioned spleen. Since the etiology of coagulative necrosis is usually vascular with loss of blood supply, the infarct occurs in a vascular distribution. Thus, infarcts are often wedge-shaped with a base on the organ capsule.
