It commonly affects the leg veins, such as the femoral vein or the popliteal vein or the deep veins of the pelvis.
Thrombosis is a multifactorial process, caused by the nature of blood flow, the consistency of the blood, and qualities of the vessel wall (Virchow's triad).

 Deep Vein Thrombosis, epidemiology, pathogenesis and risk factors MEDSTUDENTS- INTERNAL MEDICINE
Deep vein thrombosis (DVT) is a common but elusive illness that can result in suffering and death if not recognized and treated effectively.Death can occur when the venous thrombi break off and form pulmonary emboli, which pass to and obstruct the arteries of the lung.
Venous stasis predisposes the patients to venous thrombosis mainly by impairing the clearance of activated coagulation factors from the local where thrombus is formed, and vascular damage contributes to the genesis of venous thrombosis through either direct trauma, or activation of endothelial cells by cytokines.
Since venous thrombosis is difficult to recognize clinically, these hospitalized cases probably represent the tip of the iceberg.Unfortunately, the death rate from PE and DVT is substantial, and the probability of survival of affected individuals is decreased when compared with unaffected ones.
