Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura or immune thrombocytopenia, is an autoimmune primary disorder of hemostasis characterized by a low platelet count in the absence of other causes. [1][2] ITP often results in an increased risk of bleeding from mucosal surfaces (such as the nose or gums) or ...
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 ] Symptoms may include large bruises, fever, weakness, shortness ...
Treatment. None, immunosuppressants, platelet transfusion, surgical removal of the spleen [ 1 ] In hematology, thrombocytopenia is a condition characterized by abnormally low levels of platelets (also known as thrombocytes) in the blood. [ 2 ] Low levels of platelets in turn may lead to prolonged or excessive bleeding.
Thrombocythemia. In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term ...
Dependent on location. 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 ...
Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off (embolizes) and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the lungs.
In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [ 3 ] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [ 3 ] It is one of the blood cancers wherein the bone ...
Heparin-induced thrombocytopenia. Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel). When thrombosis is identified the condition ...
