It was reported that stent moved on balloon.The 95% stenosed target lesion was an area of bifurcation located in the severely tortuous and moderately calcified iliac artery.After inserting a 6fx45cm non-boston scientific (bsc) guiding sheath, an 8.0x40x135 cm express ld iliac/biliary stent was advanced over a 035 260cm non-bsc guidewire.However, during introduction, the device was difficult to advance and could not get over the bifurcation as it was too steep.It was noticed that the stent was moving along the balloon while still inside the sheath.The entire sheath along with the stent and balloon were safely removed.After inserting a new guiding sheath and crossing the lesion with an amplatz super stiff guidewire, another 8.0x40x135 cm express ld iliac/biliary stent was advanced and deployed successfully.No patient complications were reported.
