It was reported that the procedure was performed to treat a target lesion in the left common iliac artery.The 8.0 x 29 mm omnilink elite stent delivery system was implanted in the left common iliac artery.The stent was well apposed to the vessel wall and everything looked good.The physician decided to advance a sheath through the newly implanted stent, to evaluate the distal vessel for additional lesions/intervention.The sheath had resistance advancing through the stent and caused the stent to buckle and move from its original position.The sheath was removed and a dilatation catheter was advanced.Additional ballooning was able to treat the buckling.As the stent had moved from its original location, an additional 8.0 x 29 mm omnilink elite stent was implanted at the proximal lesion to cover the lesion that was uncovered when the stent moved.The patient was in stable condition post procedure.There were no adverse patient sequelae and no clinically significant delay.No additional information was provided.
