thrombus

[throm´bus]

a stationary blood clot along the wall of a blood vessel, frequently causing vascular obstruction. Some authorities differentiate thrombus formation from simple coagulation or clot formation. See also embolus.

Sites of thrombus formation. From Damjanov, 1996.

mural thrombus one attached to the wall of the heart adjacent to an area of diseased endocardium, or to the aortic wall overlying an intimal lesion. See also parietal thrombus.

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; see also mural thrombus.

mu·ral throm·bus

a thrombus formed on and attached to a diseased patch of endocardium, not on a valve or on one side of a large blood vessel.
See also: parietal thrombus.

mural thrombus

A blood clot formed within the blood and attached to the wall of a blood vessel or to the lining of a chamber of the heart. Mural thrombi are liable to break loose and form dangerous EMBOLI.

An abdominal ultrasound can delineate the transverse and longitudinal dimensions of an abdominal aortic aneurysm and may detect mural thrombus. CT with contrast and MRI are accurate, noninvasive tests to determine the location and size of abdominal aortic aneurysms and to plan endovascular or open surgical repair.
