IVC filter placement in patients undergoing surgical treatment of bone or soft-tissue tumors.

Background and Objectives: Patients with cancer to bone or soft tissues undergoing orthopedic procedures may be unable to receive pharmacologic prophylaxis for venous thromboembolism (VTE). Inferior vena cava (IVC) filters may be an effective method to prevent fatal pulmonary embolism (PE) in these patients.
Methods: Retrospective chart review performed for patients surgically treated for malignant disease of bone or soft tissue who had IVC filter placement. Type of surgery, anatomic region, and development of wound complications requiring repeat surgery were analyzed.
Results: From 2007 to 2018, 286 patients received IVC filters. Ten (3.5%) patients suffered deep vein thrombus (DVT) postoperatively. There was no acute fatal PE. Two patients suffered PE at 2 and 99 days postoperatively. Risk of DVT was comparable following surgery with endoprosthesis versus open reduction and internal fixation (p = 0.056) and with soft tissue versus bone involvement (p = 0.620). Three filter-related complications occurred. Patients disease at the femur had the highest rate of DVT.
Conclusions: Following treatment of malignant disease of bone or soft-tissues, two patients with IVC filter placement experienced nonfatal PE and three patients experienced filter-related complications. No patients in this series experienced a fatal PE.
