Biopsy Forceps-Assisted Loop Snare Technique for Complex Retrieval of Inferior Vena Cava Filter

Abstract

Severe tilt with embedded hooks is a common obstacle to successful inferior vena cava (IVC) filter retrieval. We present a case for which the biopsy forceps-assisted loop snare technique was successfully used to retrieve filters with hooks embedded in the IVC wall for which conventional retrieval failed. The technique is effective and provides a less-invasive, low-cost method for the complex retrieval of IVC filters. Introduction: Severe tilt with embedded hooks is a common obstacle to successful inferior vena cava (IVC) filter retrieval. Methods: Disposal biopsy forceps were used to remodel the filter hook in the center position to release the embedded hook from the caval wall. Results: The biopsy forceps-assisted loop snare technique was successfully used to retrieve filters with hooks embedded in the IVC wall. Conclusion: The biopsy forceps-assisted loop snare technique we present here offers a new solution for the complex retrieval of IVC filters. This technique may prove useful in cases where standard techniques at filter retrieval fail.
