Iliofemoral venous injuries: an indication for prophylactic caval filter placement.

Prophylactic placement of vena caval filters is recommended in trauma patients at high risk for pulmonary embolism (PE). We present a group of patients with iliofemoral venous trauma, and subsequent complications of deep venous thrombosis (DVT) and PE. Of twelve patients with iliac or common femoral venous injuries, seven underwent primary repair. All received DVT/ PE prophylaxis with mini-dose heparin and/or sequential compression hose. In spite of this, two patients suffered DVT, one patient had DVT and PE and one patient had clinical evidence of PE but did not undergo confirmatory testing. Three patients underwent prophylactic caval filter placement without complication. The DVT/PE complication rate in this small group was at least 43% (3 of 7). Patients with repaired iliofemoral venous injuries represent a high risk subset for DVT/PE and prophylactic caval filter placement is recommended.
