thrombus

an aggregation of blood factors, primarily platelets and fibrin with entrapment of cellular elements, frequently causing vascular obstruction at the point of its formation. The lesion and the syndrome produced by the thrombus depend on its location, e.g. pulmonary artery.

mural thrombus

one attached to the wall of the endocardium in a diseased area.

obturating thrombus

one which continues to grow distal to its site of attachment and the free end trails downstream with the current of blood.

occluding thrombus

one that occupies the entire lumen of a vessel and obstructs blood flow.

parietal thrombus

one attached to a vessel or heart wall.

saddle thrombus

one formed at the terminal aorta and extending into the iliac arteries. Occurs most commonly in cats with arterial thromboembolism.
