What is the recommended approach to DVT prophylaxis after orthopedic surgery?

• A. No prophylaxis is needed
• B. Pharmacologic prophylaxis (LMWH or DOAC) with mechanical methods as appropriate; duration depends on procedure and risk
• C. Only aspirin is used
• D. Antibiotics are used for DVT prophylaxis

Answer: (B)

After orthopedic surgery, there is a high risk of venous thromboembolism, so the recommended approach combines pharmacologic prophylaxis with mechanical methods when appropriate. Using low-molecular-weight heparin or a direct oral anticoagulant reduces clot formation, while devices like compression stockings or sequential compression devices help prevent blood pooling in the legs. The exact duration of prophylaxis is tailored to the specific procedure and the patient’s risk factors, with longer protection for more extensive surgeries or higher-risk individuals. Relying on aspirin alone is not sufficient in most orthopedic cases, and antibiotics do not prevent DVT.
