Removal method of a Supera interwoven stent invaginated during its implantation in endovascular procedure: a case report.

BACKGROUND: Supera interwoven stents (IWS) have a unique interwoven structure; thus, precise stent placement can be challenging as they are prone to elongation, shortening, and invagination. Particularly, invagination limits long-term patency. This proposed method aims to remove invaginated IWS.

CASE PRESENTATION: A 70-year-old man presented with intermittent claudication in his left lower limb. Endovascular therapy was conventionally performed, and a 5.5 × 40 mm IWS was placed after balloon dilatation; however, invagination occurred. The invaginated IWS was successfully removed by a threading 0.014" wire through the outside of the stent strut, and a snare catheter was used to hold it in place from the inside. Then, while still in place, the 0.014" wire and snare catheter were driven into the guiding sheath.

CONCLUSIONS: This practical and easy approach to remove invaginated IWS from the body relies on the particular structural characteristics.
