Other treatments for DVT included bloodletting, the administration of anti-inflammatory agents, the application of warm compresses, and elevation of the extremity to promote venous return.3, Pathophysiology of DVT and blood clot formation, As the diagnosis of blood clots became more common, clinicians began to realize that DVT formation was actually a complex process involving the interaction of multiple genetic and environmental factors.1-3,6,7 In the 1930s, a consensus was reached that three factors contribute to thrombosis: venous stasis, vessel wall damage, and hypercoagulability.1-3,6,7 These factors comprise the Virchow triad: hypercoagulability, hemodynamic change, and endothelial injury.
