As reported by the initial reporter "device placed in the external iliac and it migrated approx.4cm.They used a stiff.035 wire.The physician did not pre-dilate the lesion, but the physician did post-dilate and gained good wall-apposition.Over the stiff.035 wire, the physician inserted the inner 6fr ansel over the stiff wire - at this point the physician tried to advance the 6fr sheath through the stent (and the sheath and dilator got stuck on the mid-section of the stent).It then dislodged and migrated approx.4 cm's.At this point, the physician backed-up the sheath because she could not get the sheath all the way through.Thus, the physician backed-out the sheath and rotated it and then re-advanced the sheath.At this point the physician was able to get through the stent.She re-ballooned the stent where it landed and then re-ballooned the original segment (where she was trying to treat with the stent).The physician elected to leave the stent where it is currently located.".
