Thrombosis is the formation of a blood clot (with partial or complete blockage) in a blood vessel that prevents blood from flowing normally through the circulatory system. The affected vessel can be any vein or artery.
Thrombosis is a condition that often goes unnoticed or misunderstood. World Thrombosis Day, which is celebrated on October 13, focuses on thrombosis or "blood clots."
Blood clotting is the body's first line of defense against bleeding. When we get hurt, our clotting system forms a kind of plug or seal to protect us from losing too much blood. Our bodies often break down the clot after we have healed, but sometimes clots form improperly or do not dissolve after an injury. A blood clot that forms and remains in a blood vessel is called a thrombus.
Once formed, a thrombus can slow or block normal blood flow, or even break off and travel to an organ. A clot that travels as part of the bloodstream is called an embolism.
