A coronary stealth orbital atherectomy device (oad) was used to successfully treat a lesion in the posterior tibial artery.
A second, severely calcified lesion in the anterior tibial artery was then going to be treated with the oad via an antegrade approach.
However, when attempting to pass the guide wire through the oad, the guide wire would not pass the crown of the driveshaft.
It appeared there was something obstructing the distal opening of the driveshaft.
The wire was unable to pass through the oad and treatment of the anterior tibial artery was aborted.
It was noted that the control knob of the oad was in the correct placement for wire pass through.
It was planned to bring the patient back at a later date to treat the anterior tibial artery lesion.
It was noted there was no patient complications during the procedure.
