Supplementary material 1 Movie 1. Pre-procedural angioscope from the distal to middle superficial femoral artery. Continuous Zemporshe electronic high-resolution angioscope images pulling back in the superficial femoral artery from distal to the middle demonstrate mural thrombi with neointimal coverage in the distal edge of the Viabahn stent. (MP4 4988 kb)

Supplementary material 1 Movie 2. Pre-procedural angioscope from the middle to proximal superficial femoral artery. Continuous Zemporshe electronic high-resolution angioscope images pulling back in the superficial femoral artery from middle to the proximal demonstrate expanded polytetrafluoroethylene in the overlap, neointimal hyperplasia in the proximal edge of the Viabahn stent, and calcification in the proximal superficial femoral artery (MP4 9143 kb)

Supplementary material 1 Movie 3. The angioscope after dilatation with a cutting balloon. Continuous Zemporshe electronic high-resolution angiosope images pulling back in the superficial femoral artery from middle to the proximal demonstrate a crack in the neointima and an enlargement of the lumen area.
