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.
Thrombus. 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. The substance making up a thrombus is sometimes called cruor.
Thromboembolism is a condition in which a blood clot ( thrombus) breaks off from its original site and travels through the bloodstream (as an embolus) to obstruct a blood vessel, causing tissue ischemia and organ damage. Thromboembolism can affect both the venous and arterial systems, with different clinical manifestations and management ...
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.
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.
Embolus. An embolus ( / ˈɛmbələs /; [ 1] pl.: emboli; from the Greek ἔμβολος "wedge", "plug") is an unattached mass that travels through the bloodstream and is capable of creating blockages. When an embolus occludes a blood vessel, it is called an embolism or embolic event. [ 2] There are a number of different types of emboli ...
Superficial vein thrombosis. Great saphenous vein thrombosis. Superficial vein thrombosis ( SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis, which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness.
Diagnostic method. Doppler ultrasound, Venography [ 1] Treatment. Blood thinners, Pain medication [ 1] Thrombophlebitis is a phlebitis ( inflammation of a vein) related to a thrombus (blood clot). [ 2] When it occurs repeatedly in different locations, it is known as thrombophlebitis migrans ( migratory thrombophlebitis ). [ 3]
