Recurrent Pulmonary Embolism from Thrombi in Greenfield Filter—Case Report

Vena cava interruption using the Greenfield filter has proved to be a safe and effective method. In a series of 156 patients receiving the filter, published by Greenfield, the patency rate was 98%, and there was no mortality secondary to the filter placement. The incidence of recurrent pulmonary embolism resulting from the proximal propagation of a thrombus has been reported to be 5%. The present work reports on a case of recurrent pulmonary embolism resulting from the proximal propagation of a thrombus originating in a Greenfield filter.
