Which prophylaxis is commonly given to prevent DVT in patients with traumatic brain injury when safe to do so?

• A. Pharmacologic DVT prophylaxis (e.g., heparin or LMWH)
• B. Mechanical stockings only
• C. Routine antibiotics
• D. Antiplatelets

Answer: (A)

When it's safe to anticoagulate after a traumatic brain injury, pharmacologic DVT prophylaxis with heparin or low-molecular-weight heparin is commonly used to prevent DVT. These medications reduce the formation of clots by inhibiting the coagulation cascade, which lowers the risk of deep vein thrombosis and subsequent pulmonary embolism in patients who are immobile and at high risk after brain injury. The key is confirming stability of intracranial bleeding—usually demonstrated by imaging or clinical stability—before starting anticoagulation, because bleeding risk is a major concern in TBI. Mechanical prophylaxis, like compression stockings or pneumatic devices, can be used when there is concern about bleeding or when anticoagulation is temporarily not possible, but they are less effective at preventing DVT on their own. Routine antibiotics do not prevent DVT, and antiplatelet drugs target arterial thrombosis and are not standard for venous thromboembolism prevention in this setting.
