Conclusion: Inferior vena cava filters can be placed in patients who cannot receive concomitant anticoagulation without placing them at significantly higher risk of development of venous thromboembolism.
Can IVC filters cause blood clots?
Patients with IVC filters have a risk of developing deep venous thrombosis (DVT) – a blood clot in lower-body vein. The risk doubles two years after a filter is placed. The incidence of this complication has been estimated to be as high as 43 percent.
Is a vena cava filter permanent?
Vena cava filters may be temporary or permanent; the decision is based on an individualized basis. These filters are reserved for patients who are unable to take blood-thinning medications or for those at high risk for developing recurrent DVT with pulmonary embolism (PE).
