Studies have shown that low flow sites, such as the soleal sinuses, behind venous valve pockets, and at venous confluences, are at most risk for the development of venous thrombi.DVT most commonly involves the deep veins of the leg or arm, often resulting in potentially life-threatening emboli to the lungs or debilitating valvular dysfunction and chronic leg swelling.This results in a fibroelastic intimal thickening at the site of thrombus attachment in most patients and a fibrous synechiae in up to 11%.Furthermore, the damage to the underlying valves and those compromised by peripheral dilation and insufficiency usually persists and may progress.The lower limb deep venous system is typically thought of as 2 separate systems, one below the knee and one above.This anatomic asymmetry sometimes results in compression of the left common iliac vein by the right common iliac artery to produce May-Thurner syndrome, a left-sided iliac outflow obstruction with localized adventitial fibrosis and intimal proliferation, often with associated deep venous thrombosis.For thrombotic causes, thrombolysis and anticoagulation may be used.Over time, refinements have been made in the description of these factors and their relative importance to the development of venous thrombosis.

Although the chronic clot is not obstructive after it recanalizes, it effectively causes the venous valves to adhere in an open position, predisposing the patient to reflux in the involved segment.
Nursing Assessment of Deep Vein ThrombosisThis interaction stimulates local cytokine production and facilitates leukocyte adhesion to the endothelium, both of which promote venous thrombosis.
A blood clot is a clump of blood that is in a gelatinous, solid state.Other diseases and states can induce hypercoagulability in patients without other underlying risks for DVT.Over the past 25 years, the pathophysiology of DVT has become much better understood, and considerable progress has been made in its diagnosis and treatment.Blanched appearance of the leg because of edema (relatively rare).A useful categorization may be an acute provoking condition versus a chronic condition, as this distinction affects the length of anticoagulant therapy.Venous stasis can occur as a result of anything that slows or obstructs the flow of venous blood.
