Upon post dilation of the tacks, the balloon passed the first tack without issue but came into contact with the second tack.The balloon became caught on the second tack.The balloon pushed the tack sideways in the vessel and then down the superficial femoral artery (sfa).Eventually, the operator was able to use a stent to overlay the displaced tack, securing it against the vessel wall.A self-expanding stent was placed in the proximal sfa to cover the dissections.At the conclusion of the procedure, there was complete flow through the sfa.
