    Abstract Hypercoagulable state is not a uniform disease. It is a complex condition with an abnormal propensity for thrombosis that may or may not lead to thrombosis, depending on complex gene-gene and gene-environment interactions. The prevalence of the hypercoagulable state depends on the ethnicity and clinical history of the population being studied. The consequences of a hypercoagulable state due to thrombosis of veins and arteries are the most important cause of sickness and death in developed countries at present. Primary hypercoagulable state is an inherited condition caused by the reduced level of natural anticoagulants due to a qualitative defect or quantitative deficiency of an antithrombotic protein, or increased concentrations or function of coagulation factors. Most of the inherited abnormalities recognized to date have little or no effect on arterial thrombosis and are associated primarily with venous thromboembolism. Arterial thrombosis usually develops as a complication of atherosclerosis and patients usually have more than one traditional risk factor. Secondary hypercoagulable states generally occur as a result of a large number of transient or permanent acquired conditions that increase the tendency for formation of blood clots. New epidemiological data and clinical trials suggest that many acquired risk factors in the pathophysiology of arterial and venous thrombosis overlap and coexist for both disorders.

    Abstract The absence of the inferior vena cava is a rare congenital anomaly and represents a modest risk for deep-venous thrombosis. When associated with genetic polymorphism or other hypercoagulable states, the risk can increase several times. A case of young man with the inferior vena cava agenesia and deep-venous thrombosis of both legs triggered by the physical effort is reported. The view that the congenital inferior vena cava malformation represents a predisposition to deep-venous thrombosis in spite of well-developed collateral circulation is supported. In these circumstances, various external triggers (physical effort, hormonal contraception etc) may precipitate thrombosis. Because the patient had no other convincing and permanent risk factors for thrombosis, the lifelong anticoagulant therapy was not recommended.
