Interest in the use inferior vena caval filters has grown consistently
during the past 8 years, with 51 articles appearing in the medical li
terature during the past year. The development and introduction of sma
ller profile devices capable of percutaneous placement has opened the
field to interventional radiologists as well as surgeons. The current
periodic literature provides a variety of information regarding indica
tions for use, adverse events, experimental models, case reports, long
-term clinical studies, and information regarding new devices still in
the experimental phase. In caring for patients, it is important to co
nsider carefully the indications for filter placement, the results of
long-term performance studies, and the types of complications that can
develop from the underlying disorders as well as the devices. Many of
the reports are significant in that they provide new, carefully resea
rched information to assist the clinician; some, however, due to poor
design or small sample size, merely confuse the issues.
