The following revised diagnostic criteria for essential thrombocythemia were proposed in 2005. [13] The diagnosis requires the presence of both A criteria together with B3 to B6, or of criterion A1 together with B1 to B6. [14] The criteria are as follows: [14] A1. Platelet count > 400 × 10 3 /μL for at least 2 months. A2. Acquired V617F JAK2 ...

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 ...
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]
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [ 2 ]: 826–7[ 3 ] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the ...
Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [ 1 ] The most common cause of CVI is superficial venous reflux which is a treatable condition. [ 2 ] As functional venous valves are required to provide for efficient blood return from the lower extremities, this ...
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 ...
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 ...
