Deep vein thrombosis (DVT) is an acute vascular disorder caused by thrombi (clots) which can block blood flow in both superficial and deep veins (Riddle and Wells, 2004). Thrombi formation occurs when trauma to the endothelium (inner lining) of the vein wall triggers an inflammatory response from the body causing platelets, red blood cells, white blood cells, and other clotting factors to rush to the injured area. Veins have one-way valves that close after each contraction of the heart to prevent the back-flow of blood. Illness, injury, vessel damage, or inactivity can slow blood flow through veins causing it to pool creating a clot forming environment. Platelets and other clotting factors attach to the endothelium and form blood clots in those damaged areas (Goodman and Snyder).
