Endovascular Rescue of Sheath Perforation During Inferior Vena Cava Filter Retrieval

Inferior vena cava (IVC) filter retrieval is generally a straightforward procedure but can be challenging with unique complications. A technique used for endovascular rescue of a patient where sheath perforation by the IVC filter occurred during IVC filter retrieval is described.

A 75 year old man underwent retrieval of an IVC filter that had been in place for 10 months. Using the IVC filter retrieval set from a standard right internal jugular vein approach and the loop-snare technique, the hook and collet were captured, and the filter was collapsed into the retrieval sheath. Approximately halfway through removal of the filter through the sheath, mild resistance was encountered and the tip of the IVC filter was found to have perforated the side of the retrieval sheath. The sheath appeared to have bent slightly in this region, probably weakening the sheath wall and creating angulation, which allowed sheath perforation to occur. From a right common femoral vein approach, an Amplatz wire was used to cannulate the distal end of the perforated sheath. A balloon was then used to pull the perforated sheath with the IVC filter into a larger sheath. After removing the Tuohy-Borst and Luer adapters on the perforated sheath, it was able to be internalised and removed via the femoral vein sheath.

The endovascular rescue technique described herein may prove useful to other practitioners encountering similar situations, and the complication shows areas of caution when using the loop-snare retrieval technique.
