Loop-snare technique for difficult inferior vena cava filter retrievals.
Retrievable inferior vena cava (IVC) filters are generally retrieved without difficulties. However, when filters are tilted against the IVC wall, engaging the tip or hook of the filter can be difficult with the use of standard techniques. This report describes an alternative method of successful IVC filter retrieval by creating a wire loop between the filter legs, including the tip of the filter. This loop snare was successfully applied in eight cases after filter retrieval failed with the Recovery Cone or simple snare technique.
