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.

Increased central venous pressure, either mechanical or functional, may reduce the flow in the veins of the leg.As fibrin extravasates and inflammation occurs, the superficial tissues become edematous and hyperpigmented.Venous valvular reflux in veins not involved at the time of acute deep vein 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 Thrombosis

This interaction stimulates local cytokine production and facilitates leukocyte adhesion to the endothelium, both of which promote venous thrombosis.
