Intravascular Ultrasound—Guided Inferior Vena Cava Filter Placement in the Military Multitrauma Patients: A Single-Center Experience

Background: High velocity fragments have resulted in a multitude of complex injuries in the military patients, placing them at increased risk of venous thromboembolism. Methods: A retrospective analysis was performed of all the intravascular ultrasound (IVUS)-guided bedside inferior vena cava (IVC) filters placed between August 2003 and October 2007. Results: Fourteen patients had bedside IVUS-guided retrievable filter placement. Thirteen males and one female and the mean (+SD) injury severity scores (ISS) was 37.2 (+9.9). The most common causes of injury were explosive devices (57%), gunshot wounds (28%), rocket-propelled grenades (7%), and motor vehicle crashes (7%). Indications for filter insertion were deep venous thrombosis in 36% of patients and pulmonary embolus in 28%. Thirty five percent had filters inserted prophylactically. Conclusions: Military trauma population ISS is considerably higher than what is reported in the civilian population. The bedside IVUS-guided IVC filter insertion is particularly useful in this population.
