It was reported that the procedure was to treat a mildly calcified, moderately tortuous, 100% stenosed lesion in the left common iliac artery.Access was gained via the left common femoral artery and pre-dilatation was performed.A 7.0x59mm omni elite balloon-expandable stent (bes) was then advanced, however it could not cross the challenging anatomy and had to be withdrawn.During removal from the anatomy, the stent came off the delivery balloon due to resistance with the calcium or tortuosity and was partially in the common iliac that was to be treated and partially outside of the target lesion.The omni elite balloon was used to partially embedded the dislodged stent in the common iliac and the remainder of the stent was out of the target lesion.A 7.0x29mm omnilink elite stent was then deployed overlapping the first stent to cover the remainder of the lesion and secure the dislodged stent.There were no reported adverse patient effects and no clinically significant delays in the procedure.No additional information was provided.
