A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein.
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis , the cessation of blood loss from a damaged vessel, followed by repair.
The clotting factors are made either from human blood or by recombinant methods. [16] Up to 20% of people develop antibodies to the clotting factors which makes treatment more difficult. [ 3 ] The medication desmopressin may be used in those with mild haemophilia A. [ 16 ] Studies of gene therapy are in early human trials.

This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack. [1] Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis, a buildup of cholesterol and fats in the artery walls. The smaller vessel diameter allows less blood ...
Physicians specialized in hematology are known as hematologists or haematologists. [2] Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope, interpreting various hematological test results and blood clotting test results.
Joint capsule. Haemophilia A's phenotype has a quite wide range of symptoms encompassing both internal and external bleeding episodes. Individuals with more severe haemophilia tend to experience more intense and frequent bleeding, whereas those with mild haemophilia typically exhibit milder symptoms unless subjected to surgical procedures or significant trauma.
The plug provides a temporary blockage of the break in the vasculature. As such, platelet plug formation occurs after vasoconstriction of the blood vessels but before the creation of the fibrin mesh clot, which is the more permanent solution to the injury. The result of the platelet plug formation is the coagulation of blood.
