Retrospective Multicenter Comparison Between Viabahn Covered Stent-Grafts and Supera Interwoven Nitinol Stents for Endovascular Treatment in Severely Calcified Femoropopliteal Artery Disease: The ARMADILLO Study (Adjusted Retrospective coMparison of scAffolDs In caLcified LesiOns)

The previous single-arm registries showed the acceptable primary patency after endovascular therapy (EVT) using covered stent-graft (CSG) and Supera interwoven nitinol stent (Supera peripheral stent [SPS]) in calcified femoropopliteal lesions. The aim of this study was to compare the safety and efficacy between CSG and SPS in calcified femoropopliteal lesions in clinical practice.
