Prophylactic measure DVT includes -
Warfarin
Heparin
Graduated elatic compression stocking
All of the above
Heparin anticoagulates by binding to and accelerating the activity of antithrombin,thus preventing additional thrombus formation and permitting endogenous fibrinolytic mechanisms to lyse clot that already has formed.Warfarin is a vitamin K antagonist that prevents carboxylation activation of coagulation factors 2,7,9,10.Daily use of below-knee 30 to 40 mmHg vascular compression stockings also act as a prophylactic measure for DVT.
