Prevention of Deep Venous Thromboembolism

Area of Science:

• Medical research
• Trauma surgery
• Vascular medicine

Background:

• Combat wounds elevate the risk of deep venous thrombosis (DVT) and pulmonary embolism (PE), collectively known as venous thromboembolism (VTE).
• Unique risk factors in combat casualties include hypercoagulable states, severe extremity trauma, immobility, and extended transport times.
• These factors necessitate proactive VTE prevention strategies.

Purpose of the Study:

• To outline the Department of Defense (DoD) Joint Trauma System (JTS) Clinical Practice Guideline (CPG) for VTE prevention in combat-injured patients.
• To detail current recommendations for preventing DVT and PE.
• To address the role of inferior vena cava filters (IVCFs) in PE prophylaxis.

Main Methods:

• Review of existing literature and guidelines on VTE prophylaxis in trauma patients.
• Development of evidence-based recommendations by the JTS.
• Inclusion of pharmacological and mechanical prophylaxis methods.

Main Results:

• Aggressive prophylaxis is crucial for DVT and PE prevention in combat casualties.
• Recommended prophylaxis includes sequential compression devices and low-dose unfractionated or low molecular weight heparin.
• Inferior vena cava filters are indicated when chemical prophylaxis is contraindicated or ineffective.

Conclusions:

• Implementing comprehensive VTE prophylaxis strategies is essential for managing combat-injured patients.
• The guideline provides a framework for preventing DVT and PE in this high-risk population.
• Early and consistent application of prophylaxis can reduce VTE-related morbidity and mortality.
