Inferior vena caval filters: key considerations.
Surgical interruption of the inferior vena cava (IVC) as a means to prevent pulmonary embolism and its consequences has been entertained since the end of the 19th century. Initial methods were crude, however, but their deficiencies led to the development of newer techniques. Despite increasing indications and use of permanent IVC filters there remains controversy regarding their efficacy and complications. The purpose of this article is to review the pertinent literature and, it is hoped, aid in the development of a rational approach to the use of IVC filters. The evolving data regarding the retrievable filters are also discussed.
