Different types of thrombi are described including (1) formed intraluminal thrombi (thromboemboli); (2) fibrin (fibrinoid) deposits within vessel walls, which may or may not propagate into vessel lumina (20,31); and (3) platelet-fibrin complexes that form within vessels with a disrupted wall or a lumen bridged by endothelial or myointimal cells
that facilitate deposition of thrombus material and potential thrombus formation.
