Balloon-assisted inferior vena cava filter retrieval: A novel technique to enhance irretrievable filter extraction

Although the use of inferior vena cava (IVC) filters has expanded, complications have led to the recommendation to remove all unnecessary filters. Several techniques exist to aid in retrieving irretrievable IVC filters. The balloon-assisted retrieval technique has previously been described to aid in cases of an embedded hook. This report describes an alternative use of the balloon-assisted technique, specifically to aid in the retrieval of Greenfield IVC filters in cases of strut perforation of the cava wall. This technique was successfully performed in six out of six attempted cases with no associated complications.
