Deep Venous Thrombosis (DVT) - Risk Reduction

Procedure-specific risk reduction
Specific agents for risk reduction
  • apixaban (oral factor Xa inhibitor)
  • aspirin  (see role of ASA for DVT prophylaxsis)
  • danaparoid
    • low molecular wt glycosaminoglycan with potent anti factor Xa activity
  • fondaparinux
  • low molecular weight heparins
    • may be more effective in total hip arthroplasty as compared to total knee arthroplasty
    • typically LMWH are administered 12-24 hours following surgery and is continued for 14 days
  • recombinant hirudin desirudin
    • may offer up to 86% risk reduction of DVT
    • direct inhibitor of thrombin
  • rivaroxaban (Xarelto)
    • highly selective direct factor Xa inhibitor with oral bioavailability and rapid onset of action
    • availability – 10 mg, 15 mg, and 20 mg tablets
    • indications (non-comprehensive)
      • prophylaxis of deep vein thrombosis (DVT) in adults undergoing hip and knee replacement
      • treatment of patients with DVT and pulmonary embolism (PE)
      • long-term treatment to prevent recurrence of DVT and PE
    • references
  • SQ heparin
  • thrombolytic therapy
  • warfarin
Bleeding complications
  • difficulty in assessing the risk of bleeding complications among various agents depends mainly on dose of meds used and amount of monitoring
    • i.e., to achieve the desired anticoagulation effect (and DVT prophylaxsis), how much bleeding are we willing to accept?
    • published bleeding complications note 5% bleeding from LMWH, 3% bleeding from coumadin, and 2.5% from SQ heparin
    • in contrast, the bleeding complications from ASA is approximately 0.4%
Mechanical methods for risk reduction
Epidural anesthesia
