An inferior vena cava (IVC) filter is a useful treatment to prevent a pulmonary embolism (PE) in patients with DVT. Since the introduction of IVC filters more than 30 years ago, there has been a steady improvement in the design, ease and safety of the delivery system. The use of a temporary filter has also increased as performing thrombolysis and thrombectomy has increased. Today all of the commonly used filters can be placed via a peripheral vein by using the standard percutaneous Seldinger (Ed note: check the spelling) technique. However this typically requires fluoroscopy, intravenous contrast agents, radiation exposure and transport of the patient to the interventional or operating suite. As the multiple trauma injured or critically-ill intensive care unit patients often require inotropic and ventilator support, transporting these patients to these facilities can be hazardous. The following report describes two cases of VTE patients who underwent percutaneous placement of an IVC filter with using duplex ultrasound guidance. Identification of the renal vein and artery is important to decide the infrarenal level. The first case was an 84 years female with right ilio-femoral DVT and pulmonary embolism. To prevent recurrence of PE, we decided to insert an IVC filter. The second case was a 47 years female with right femoral DVT together with left pulmonary embolism and infarction. She also had thrombocytopenia, which is a contraindication for anticoagulation. IVC filter insertion can be safely performed under ultrasound guidance. This technique will reduce the risk and complexity of inserting an IVC filter in selected multiple injured trauma patients.
