Physician was attempting to use a hawkone directional atherectomy along with a non-medtronic 6fr 45cm sheath and a 0.
014" spider wire during procedure to treat a severely calcified lesion in the proximal superficial femoral artery (sfa).
The vessel was not pre or post dilated.
Ifu was followed.
During withdrawal, moderate resistance was felt and the tip detached, it separated at the hinge pin.
The became completely detached near the rapid exchange port.
The guidewire lock-up/prolapse/lumen torn/ripped occurred.
The device advanced over bifurcation but no resistance felt.
Guidewire was hydrated at preparation.
The guidewire prolapsed and it cause embolization.
The guidewire tor from the distal tip but did not lock-up on the catheter.
The tip was left in the body as was unable to be retrieved.
Patient was sent to surgery for open retrieval.
The target lesion was right ostial sfa.
Hawkone device became stuck and tip dislodged due to wire wrap and prolapse upon removal.
Multiple attempts were made to straighten out and unwrap wire with no success.
Upon attempting to remove spider wire, hawk device, and sheath simultaneously the tip separated upon reaching the contra-lateral left common femoral side and became lodged into the left profunda artery.
Multiple attempts were made to snare the spider wire an d tip from the contra-lateral side but were unsuccessful due to a hard protrusion from the proximal end of the tip becoming embedded in the arterial wall.
Contra-lateral guide catheter and snare left in place with capture of spider wire basket and proximal tip with distal tip embedded in profunda artery.
Patient was sent to the operating room for open retrieval.
No further patient injury reported.
