The ravages of thromboembolic disease continue to plague patients despite improvements in diagnostic imaging and anticoagulation regimens. In certain cases, standard medical therapy for thromboembolism is contraindicated, results in complications, or fails to adequately protect patients from embolic insults. These patients are treated with insertion of inferior vena cava (IVC) filters. Although it appears that IVC filters do reduce long-term pulmonary embolism (PE) rates, there may be a higher associated incidence of IVC thrombosis and lower-extremity deep venous thrombosis (DVT) than with anticoagulation alone. This article will address attributes of the theoretical ideal IVC filter, recently introduced IVC filters, complications of use of IVC filters, and results of recent IVC filter studies. Alternative sites for filter placements are then reviewed, along with use of temporary and retrievable IVC filters and use of IVC filters for prophylactic situations.

Venous thromboembolism (VTE) in trauma patients is a capricious problem that continues to plague trauma surgeons and critical care physicians alike. Pharmacologic preventions of VTE with anticoagulants are often contraindicated in the trauma patient because of risk of bleeding diathesis. Mechanical prophylaxis in the form of venous compression boots often cannot be placed because of external fixators, swelling, and so forth. Providing effective VTE prophylaxis, while at the same time providing definitive care for the trauma patient, can be a nightmare. This review will first discuss the incidence and prevalence of VTE, as well as investigate the condition's diagnosis and treatment. Solutions to frequently encountered clinical dilemmas in managing VTE in trauma patients are considered in the form of frequently asked questions. Diagnostic techniques such as magnetic resonance venography, D-dimer, and various computed tomography methods are evaluated. Recent literature on preventive pharmacologic therapies is explored. The authors also consider whether vena cava filters prevent pulmonary embolism in trauma patients.
