Fat Embolism in Trauma Fat embolism is the blockage of blood vessels by fat globules. The emphasis is on blockage which separates fat embolism from lipaemia in which the plasma fat is a fine emulsion readily passing the smallest capillaries. Embolism by fat has features different from other forms of embolism: it is predominantly a microembolism affecting the minute vessels, especially capillaries and arterioles; the emboli are fluid and deformable. Hence, the vascular occlusion is likely to be temporary."
