ADVERTISEMENTS

IVC filter usage has increased rapidly during the past thirty years. In 1979, 2,000 IVC filters were used, while in 2007, almost 167,000 filters were implanted, and the market for IVC filters is only expected to increase, with an estimated 259,000 IVC filters to be deployed in 2012 (Smouse and Johar, Endovascular Today, February 2010). 

 

Since 2005, the FDA has received 921 device adverse event reports involving IVC filters, of which 328 involved device migration, 146 involved embolizations (detachment of device components), 70 involved perforation of the IVC, and 56 involved filter fracture. Some of these events led to adverse clinical outcomes in patients. These types of events may be related to a retrievable filter remaining in the body for long periods of time, beyond the time when the risk of PE has subsided.  

 

The FDA is concerned that these retrievable IVC filters, intended for short-term placement, are not always removed once a patient?s risk for PE subsides. Known long term risks associated with IVC filters include but are not limited to lower limb deep vein thrombosis (DVT), filter fracture, filter migration, filter embolization and IVC perforation.
