There was a flow-limiting dissection in the distal common femoral artery (cfa) and a 5.5mm x 80 supera stent was deployed.We then went to overlap a 6.5 x 40 supera stent with this.The intended location was for the right common femoral artery in the mid to distal segment.At the point of near complete deployment, the unlocking and unleashing mechanism from the supera shaft was stuck.It did not work.In the process of pulling the carcass of the stent out, the supera stent also migrated north to the aortic bifurcation.We were able to retrieve the distal plastic nose ring of the supera.
