Spontaneous disruption of two Greenfield vena caval filters.
Two cases of fractured Kimray-Greenfield vena caval filter struts in patients with pulmonary embolism are reported. Both filters were inserted without complications by means of a jugular approach. Postoperative radiographs demonstrated correct positioning of the filter. During the follow-up period in both cases the devices migrated caudally and penetrated the caval wall; however, the patients remained asymptomatic. Radiographs should be obtained in the follow-up period to ensure proper positioning of the vena caval filter even in asymptomatic patients.
