While venous thrombosis of the legs is the most common form, venous thrombosis may occur in other veins. These may have particular specific risk factors: [5] Cerebral venous sinus thrombosis, cavernous sinus thrombosis and jugular vein thrombosis: thrombosis of the veins of the brain and head
Thrombosis may occur in veins (venous thrombosis) or in arteries (arterial thrombosis). Venous thrombosis (sometimes called DVT, deep vein thrombosis) leads to a blood clot in the affected part of the body, while arterial thrombosis (and, rarely, severe venous thrombosis) affects the blood supply and leads to damage of the tissue supplied by ...
Various risk factors contribute to VTE, including genetic and environmental factors, though many with multiple risk factors never develop it. [57] [58] Acquired risk factors include the strong risk factor of older age, [5] which alters blood composition to favor clotting. [59] Previous VTE, particularly unprovoked VTE, is a strong risk factor. [60]
Studies of the pathophysiologic mechanisms for the increased risk of Venous thrombosis embolism or VTE after long-distance travel have not produced consistent results, but venous stasis appears to play a major role; other factors specific to air travel may increase coagulation activation, particularly in passengers with individual risk factors ...
In detailing the pathophysiology surrounding pulmonary embolism, he alluded to many of the factors known to contribute to venous thrombosis. While these factors had already been previously established in the medical literature by others, [ 10 ] [ 11 ] for unclear reasons they ultimately became known as Virchow's triad.
In general, men are more likely than women to experience repeated episodes of venous thrombosis. [5] People with factor V Leiden are at a relatively low risk of thrombosis, but may develop thrombosis in the presence of an additional risk factor, such as immobilization. Most people with the prothrombin mutation (G20210A) never develop thrombosis ...
These include people with venous diseases, conditions which affect circulation, or risk factors for developing blood clots. These include: A prior history of DVT
These risk factors include age, cancer, history of thromboembolism, pregnancy, use of oral contraceptive medications (containing estrogen), [4] hormone replacement therapy, recent surgery, and certain autoimmune diseases (especially Behçet's and Buerger's diseases). [3] Other risk factors include immobilization (stasis) and laparoscopy. [1]
