Abstract

A 68-year-old woman presented with chest pain and dyspnea and was diagnosed with a massive pulmonary embolism. Bleeding colon cancer was detected incidentally during anticoagulation therapy. After stabilization, she underwent surgical resection of the cancer with insertion of an inferior vena cava filter and was treated with rivaroxaban as antithrombotic therapy thereafter. Unexpectedly, thrombotic obstruction of the filter was revealed on a computed tomography scan taken in preparation for removing the device. After switching to warfarin, the obstruction had resolved at the 4-week follow-up examination. We discuss what to consider when performing antithrombotic therapy in patients with an inferior vena cava filter.
