What are the different types of IVC filters?

There are 2 different types of IVC filters: permanent or retrievable.

Retrievable filters are meant for short-term protection and are only intended to stay in the patient’s body until the risk of pulmonary embolism subsides. A safety concern noted by the FDA is that retrievable filters are often left unnecessarily implanted within patients for longer than needed. Complications can arise when the filters are left in place to long, including breaking away from their original location and lacerating internal organs.

A 2014 safety communication by the FDA recommended that all retrievable filters should be removed between 29 and 54 days after implantation, if the PE had subsided. Unfortunately, research has shown that less than 10% of filters are effectively removed in time.
