The stealth peripheral orbital atherectomy device (oad) was operated on low, medium and high speeds for one treatment pass each, in a calcified tibioperoneal trunk artery.
It is believed that damage to the intima occurred, as intima debris was noted to travel distally to the foot.
Balloon angioplasty was performed to push the debris into a nearby collateral vessel.
The area of the vessel wall where suspected intima damage occurred did not require additional intervention.
Upon removal, tissue was observed on the crown of the oad.
The patient was in stable condition.
