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 ...
Deep vein thrombosis. Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. [9][a] A minority of DVTs occur in the arms. [11] Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms. [1]
In cases of reactive thrombocytosis of more than 1,000x10 9 /L, it may be considered to administer daily low dose aspirin (such as 65 mg) to minimize the risk of stroke or thrombosis. [11] However, in essential thrombocythemia where platelet counts are over 750x10 9 /L or 1,000x10 9 /L, especially if there are other risk factors for thrombosis ...
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.
Thrombophilia. An ultrasound image demonstrating a blood clot in the left common femoral vein. Thrombophilia (sometimes called hypercoagulability or a prothrombotic state) is an abnormality of blood coagulation that increases the risk of thrombosis (blood clots in blood vessels). [ 1 ][ 2 ] Such abnormalities can be identified in 50% of people ...
Post-thrombotic syndrome. Other names. postphlebitic syndrome, venous stress disorder. Person with post-thrombotic syndrome and leg ulcers. Specialty. Hematology. Post-thrombotic syndrome (PTS), also called postphlebitic syndrome and venous stress disorder is a medical condition that may occur as a long-term complication of deep vein thrombosis ...
Leopold von Schrötter. Paget–Schroetter disease (which evolved from a venous thoracic outlet syndrome) is a form of upper extremity deep vein thrombosis (DVT), a medical condition in which blood clots form in the deep veins of the arms. These DVTs typically occur in the axillary and/or subclavian veins.
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 ...
