A diamondback peripheral orbital atherectomy device was used to successfully treat a lesion located in the superficial femoral artery.Balloon angioplasty was performed, and no complications were apparent at that time.The patient presented with calf pain the following day, and the physician believed a perforation had occurred.No treatment was performed as it was believed the perforation would resolve without intervention.Imaging was viewed on (b)(6) 2020, and the perforation was confirmed.Per the opinion of the physician, it could not be conclusively determined if the cause of the perforation was the viperwire guide wire, or the non-csi guide wire that was also present when the perforation occurred.
