Patient was undergoing coronary intervention (ffr) of obtuse marginal vessel of the left circumflex coronary artery using aeris pressure wire.During advancement into om1, usual negotiation of the ffr wire through distal curvature resulted in wire becoming non-responsive.Wire carefully counter-rotated to remove but still would not respond normally.Ultimately wire tip fragmented and was loose in om1.Two soft wires looped around wire fragment which was atraumatically brought into the left main.While preparing to snare, wire embolized to the abdominal aorta and appeared to lodge in a lumbar artery.Retrieval was attempted but the wire fragment migrated more distally into lumbar artery.Attempt to snare unsuccessful and resulted in dissection in lumbar artery with symptoms requiring ptca to restore flow.Three wires were then passed distal to wire fragment and was able to engage and retrieve the wire into the guide.The entire wire-device-guide unit was pulled out under fluoroscopy with confirmed full retrieval of the ffr wire.
