During a peripheral procedure, a csi orbital atherectomy device was used to treat a lesion from the superficial femoral artery (sfa) through the anterior tibial (at) artery.The lesion had 60-80% stenosis, was heavily calcified, and the vessels had mild tortuosity.The at was treated with balloon angioplasty, and orbital atherectomy was then performed from the sfa to the popliteal artery with 6 treatments on low speed, 3 treatments on medium speed, and 6 treatments on high speed.Additional balloon angioplasty was performed from the popliteal artery through the at.Haziness was identified on imaging in the mid-at.It was noted that flow after orbital atherectomy had been normal.Small, hard, white matter was aspirated, and the haziness was no longer visible under fluoroscopy.The opinion of the physician was that the white matter was a result of orbital atherectomy.Additional balloon angioplasty was performed in the sfa to complete the procedure with satisfactory results.
