a blood clot within the blood vessels - typically lodges somewhere in the circulatory system and blocks bloodflow to the organs or tissue distal to the blockage
A blood clot in the veins This may occur in the legs or pelvis following major surgery
Thrombosis is the formation of a blood clot in a person's heart or in one of their blood vessels, which can cause death. see also coronary thrombosis. thromboses a serious medical problem caused by a clot forming in your blood that prevents the blood from flowing normally. Formation of a blood clot (thrombus) in the heart or a blood vessel. Contributing factors include injury to a blood vessel's lining from inflammation (thrombophlebitis) or atherosclerosis, blood flow that is turbulent (e.g., from an aneurysm) or sluggish (e.g., from prolonged bed rest), or coagulation abnormalities (e.g., from high numbers of platelets or excessive fats in the blood). Thrombosis, especially in deep veins of the leg, is a particular danger after major surgery. A thrombus can block blood flow at the point of clot formation or break free to block it elsewhere (embolism)
Clotting The formation of blood clots on, or inside, of a blood vessel, heart chamber, or medical device
the formation of a blood clot in one of the cerebral arteries of the head or neck that stays attached to the artery wall until it grows large enough to block blood flow
Blood clots in the legs that can break off and go to the lungs causing respiratory distress or failure
Thrombosis differs from an embolism in that a thrombus consisting of a blood clot, or clump of blood cells, forms inside the affected blood vessel; a fragment of a thrombus becomes an embolus if it is dislodged and moves through the bloodstream to create an obstruction, or embolism Thrombi may be prevented from growing by the use of anticlotting drugs, such as aspirin, Coumadin, or heparin
The process of formation of a blood clot within the blood vessel of a living person
The obstruction of a blood vessel by a clot formed at the site of obstruction; distinguished from embolism, which is produced by a clot or foreign body brought from a distance
the formation or existence of a blood clot; may be a life-threatening condition as it can occlude a vessel and stop the blood supply to an organ or body part
