<unk>  (sometimes called hypercoagulability or a prothrombotic state) is an abnormality of blood coagulation that increases the risk of thrombosis (blood clots in blood vessels). Such abnormalities can be identified in 50% of people who have an episode of thrombosis (such as deep vein thrombosis in the leg) that was not provoked by other causes. A significant proportion of the population has a detectable<unk>  abnormality, but most of these develop thrombosis only in the presence of an additional risk factor. There is no specific treatment for most<unk> s, but recurrent episodes of thrombosis may be an indication for long-term preventive anticoagulation. The first major form of<unk>  to be identified by medical science, antithrombin deficiency, was identified in 1965, while the most common abnormalities (including factor V Leiden) were described in the 1990s.
