Definitions for "Thrombus"
A clot of blood formed of a passage of a vessel and remaining at the site of coagulation.
A tumor produced by the escape of blood into the subcutaneous cellular tissue.
A solid mass made of various combinations of platelets, fibrin, clotting factors and the cellular elements of blood that forms within the heart or blood vessels. Thrombus often forms on the injured wall of a vessel, but loose thrombi can also form in the left atrium of the heart if it is not contracting normally so that blood stagnates there. A thrombus may break free and become an embolus.
