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.

, pl.

throm·bi

(throm'bŭs, -bī),
A clot in the cardiovascular systems formed during life from constituents of blood; it may be occlusive or attached to the vessel or heart wall without obstructing the lumen (mural thrombus).
[L. fr. G. thrombos, a clot]

thrombus

(thrŏm′bəs)
n. pl. throm·bi (-bī)
A fibrinous clot formed in a blood vessel or chamber of the heart.

thrombus

[throm′bəs] pl. thrombi
Etymology: Gk, thrombos, lump
1 an aggregation of platelets, fibrin, and red blood cells that attaches to the interior wall of a vein or artery, sometimes occluding the lumen of the vessel. Kinds of thrombi include agonal thrombus, hyaline thrombus, laminated thrombus, and white thrombus. Compare embolus.
2 a blood clot

thrombus

Hematology An intravascular blood clot formed in vivo from fibrin thread accumulation around a platelet plug. See Deep vein thrombosis, Pulmonary thromboembolism.

throm·bus

, pl. thrombi (throm'bŭs, -bī)
A clot in the cardiovascular system formed during life from constituents of blood; it may be occlusive or attached to the vessel or heart wall without obstructing the lumen (mural thrombus).
Synonym(s): blood clot.
[L. fr. G. thrombos, a clot]

thrombus

A blood clot forming especially on the wall of a blood vessel. This is commonly the result of local damage to the inner lining of the vessel (the endothelium).

Thrombus

Formation of a blood clot within the vascular system. A thrombus becomes an embolism if it breaks away and blocks a blood vessel.

thrombus

occlusive/non-occlusive intravascular clot; may partially/totally detach to occlude a downstream vessel

throm·bus

, pl. thrombi (throm'bŭs, -bī)
A clot in the cardiovascular system formed during life from constituents of blood; it may be occlusive or attached to the vessel or heart wall without obstructing the lumen (mural thrombus).
Synonym(s): blood clot.
[L. fr. G. thrombos, a clot]

thrombus (throm´bus),

n a blood clot in a vessel or in one of the chambers of the heart that remains at the point of its formation.

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.

Patient discussion about thrombus

Q. How can I prevent blood clots? I am 45 years old and am supposed to go on a business trip overseas. The flight itself is 12 hours long and then I have to continue traveling by bus. Could this cause me to have blood clots? If so, how can I prevent it?

A. Always walk as much as you can on the plane. Also, rotate your ankels in circles. Sometimes try to use your ankels and make the alphabet with them. Have fun..
