Unexpected paradoxical embolization following catheter-directed thrombectomy with the FlowTriever™ system in a patient with pulmonary embolism: a case report.

Whether the deep venous thrombosis is the source of embolization or the catheter-directed retrieval of clots may have transported clot material to the right atrium which further on embolized systemically will remain unclear. Yet, we have to consider it as a potential complication in catheter-directed treatment of PE in patients with a PFO.
