title: Structural failure of a Greenfield filter.
abstract: A unique case is discussed in which a Greenfield filter failed structurally after less than 1 year in situ. In the absence of external trauma, two struts of the filter separated from the hub and migrated into the retroperitoneal tissues. A brief discussion of the complications of Greenfield filters concludes with a possible explanation of this particular problem.
