Migration of a thrombus in the pulmonary circulation is the leading cause of pulmonary embolism (PE). It can be prevented mechanically by implanting a vena cava filter (VCF) in the inferior vena cava. The implation of a VCF is indicated for patients with acute PE and a contraindication to anticoagulation, with an acute deep vein thrombosis (DVT) without PE and a contraindication to anticoagulation or with acute venous thromboembolism (less than 3 months) in whom an interventional gesture at hemorrhagic and thromboembolic risk contraindicates anticoagulation.
The purpose of this study is to describe the rates of implantation, removal and complications associated with the use of the optional ALN OATF VCF in current practice.
739 studies on the registry are indexed under Pulmonary Embolism; 159 are open to participants now.
