Contrast stainings outside the stents of the superficial femoral artery after polymer-free drug-eluting peripheral stents implantation.
2015
A 65-year-old man with occlusion of the left superficial femoral artery (SFA) underwent the endovascular therapy (EVT). A successful EVT was performed with three paclitaxel-eluting peripheral stents (Zilver PTX®) implanted in the left SFA. Angiography 1 year later showed an exudation of contrast outside the stent struts, and intravascular ultrasound, and optical coherence tomography also showed incomplete stent apposition with remarkable positive vascular remodeling. Zilver PTX® stent is a polymer-free stent and it is unclear that the reason why the patient treated with Zilver PTX® stents in the SFA lesions caused the contrast stainings outside the stents. However, we need more careful long-term follow-up of this patient for late thrombosis.
