For DVT prophylaxis in postoperative patients, what is a commonly used approach?

• A. Mechanical devices only
• B. Warfarin for 6 weeks
• C. Aspirin alone
• D. Pharmacologic prophylaxis with low-molecular-weight heparin (LMWH)

Answer: (D)

Preventing post-op venous thromboembolism relies on pharmacologic prevention because it addresses the clotting tendency directly. Low-molecular-weight heparin is commonly used because its effect is predictable after a subcutaneous injection, it doesn’t require routine lab monitoring, and it has a favorable safety profile with a lower risk of heparin-induced thrombocytopenia compared with unfractionated heparin. It provides rapid protection after surgery and is more effective for DVT prevention than aspirin alone. Warfarin is less ideal in the immediate postoperative period due to slow onset, need for INR monitoring, and dietary/drug interactions. Mechanical devices like compression stockings or pneumatic devices help reduce risk but are not as effective when used alone in many surgical patients. Therefore, pharmacologic prophylaxis with LMWH is the commonly used approach.
