The normal clotting process depends on the interplay of various proteins in the blood. Coagulopathy may be caused by reduced levels or absence of blood-clotting proteins, known as clotting factors or coagulation factors. Genetic disorders, such as hemophilia and Von Willebrand disease, can cause a reduction in clotting factors. [2]
The excessive clotting that occurs in this disorder is almost always restricted to the veins, [11] where the clotting may cause a deep vein thrombosis (DVT). If the venous clots break off, these clots can travel through the right side of the heart to the lung where they block a pulmonary blood vessel and cause a pulmonary embolism.
Hypoprothrombinemia is a rare blood disorder in which a deficiency in immunoreactive prothrombin (Factor II), produced in the liver, results in an impaired blood clotting reaction, leading to an increased physiological risk for spontaneous bleeding.
Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
Haemophilia B, also spelled hemophilia B, is a blood clotting disorder causing easy bruising and bleeding due to an inherited mutation of the gene for factor IX, and resulting in a deficiency of factor IX. It is less common than factor VIII deficiency (haemophilia A). [3]
Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss ...
