Barriers to IVC filter retrieval include physician refusal, perhaps due to lack of appreciation for consequences of permanent devices, ongoing contraindication to anticoagulation, long indwelling time, and loss of patients to follow-up. To decrease the number of IVC filters that are left in place permanently, we should first help educate clinicians to identify appropriate candidates for placement. Recent studies suggest that only half of all IVC filter placements were appropriate per professional society guidelines.4 Next, a system should be in place to track the fate of the device. Leaving this up to the patient or primary care physician is not acceptable. Institution of an IVC filter clinic has been show to result in a 2-fold increase in retrieval rates.5 A weekly multidisciplinary review of filter placement request and indication, repositioning, and retrieval resulted in an 80% reduction in retained devices without an absolute indication.6 Mandatory postmarketing registries would provide a way to assess safety and efficacy of various devices and could provide valuable information on both complication retrieval rates.
