摘要

An 84-year-old woman who presented with a nonhealingulceration on a left toe despite treatmentfor several months was admitted to hospital. In thefirst session, the patient underwent endovascular treatment(EVT) for chronic total occlusion of the left superficialfemoral artery with severe calcification, and a Supera stent(5.5×150mm) (SUPERATM stent, Abbott Vascular, SantaClara, CA, USA) was deployed. After the stent was releasedfrom its sheath, compression of the Supera stent wasobserved on angiography. Subsequently, post-dilatationwas performed with a 6.0×150-mm high-pressure balloon(SHIDEN HP?, KANEKA Medics, Osaka, Japan).Final angiogram and intravascular ultrasound indicatedan acceptable result. On high-resolution angioscopy(Forwardlooking?, OVALIS, Osaka, Japan) 1 week afterEVT, the Supera stent was compressed, with the appearanceof a spider nest (Figure A). It had the appearance of a spiderweb, i.e., the wires constituting the stent intertwine eachother. Even though the compression was mild and uniform(Figure B,C), the wire of the Supera stent protruded intothe vessel lumen. Given that these lesions will not be endothelialized,the risk of a thrombotic event will persist.
