Retained inferior vena cava filter retrieval: Novel approach using tiger tooth foreign body holding forceps

Abstract

Only about one-third of all inferior vena cava (IVC) filters are successfully retrieved. This is largely due to factors such as IVC occlusion, filter tilt, and caval wall penetration among other reasons. IVC filter retrieval methods currently followed in practice involve the use of standard snares and wires, endobronchial forceps, LASER-tipped sheaths, and even open surgery. However, the success rate of filter retrieval continues to remain low, thereby increasing the risk of complications associated with retained IVC filters. This warrants a need to explore and adopt newer techniques of IVC filter retrieval. In this case report, we describe the novel use of a tiger tooth foreign body holding forceps in the successful retrieval of a retained IVC filter in an elderly man with intracranial hemorrhage.
