Which of the following is a standard approach to DVT prevention in the neurocritical care setting for TBI?

• A. Pharmacologic prophylaxis with anticoagulants once bleeding risk is stabilized
• B. Mechanical prophylaxis with compression devices
• C. No prophylaxis due to risk
• D. Delayed ambulation only

Answer: (B)

In the neurocritical care setting for traumatic brain injury, preventing DVT must balance the high risk of clotting with the danger of worsening brain bleeding. The safest and most practical first-line strategy is mechanical prophylaxis using compression devices. These devices reduce venous blood flow stagnation in the legs without introducing anticoagulant effects that could aggravate intracranial hemorrhage.

Pharmacologic prophylaxis with anticoagulants has an important role, but it’s typically started later, only after imaging shows stability and bleeding risk is acceptably low. Relying on ambulation alone isn’t reliable in the acute phase, and choosing to withhold all prophylaxis leaves patients vulnerable to DVT. Therefore, mechanical prophylaxis is the standard initial approach.
