[Implant of embolic protection filters in duplicated vena cava].

We present the case of a patient with venous thromboembolic disease and contraindication to anticoagulation, where the incidental finding of a duplication of the inferior vena cava was made. This observation determined the need to implant two embolic protection filters. Although this vascular anomaly is rarely present, it is important to keep this possibility in mind to ensure that proper protection is provided when inferior vena cava filters are implanted.
