Heit MD Introduction Symptomatic thrombosis is caused by dysregulation of the normal hemostatic response to vessel wall injury that occurs with exposure to a clinical risk factor . surgery trauma or hospitalization for acute medical illness . Vessel wall injury may be anatomic . venous endothelial microtears within vein valve cusps due to stasis or rupture of a lipid-rich atherosclerotic plaque or non-anatomic . cytokine-mediated endothelial expression of adhesion molecules or downregulation of thrombomodulin expression related to the acute inflammatory response . However the vast majority of persons exposed to a clinical risk factor do not have development of symptomatic thrombosis. We now recognize that clinical thrombosis is a multifactorial and complex disease that becomes manifest when a person with an underlying predisposition to thrombosis thrombophilia s is exposed to additional risk factors. Emerging evidence suggests that individual variation in the regulation of the procoagulant anticoagulant fibrinolytic and acute inflammation or innate immunity pathways most likely accounts for the development of clinical thrombosis in exposed persons. Thrombophilia is defined as a predisposition to thrombosis. Thrombophilia is not a disease per se but may be associated with a disease . cancer with drug exposure . oral contraceptives or with a specific condition . pregnancy or post partum acquired thrombophilia Portions of this manuscript have been previously published in Heit JA.
