Orbital atherectomy (oa) treatment was successfully performed in the peroneal artery via antegrade approach.The peripheral orbital atherectomy device (oad) and viperwire guide wire were removed from the patient's body, and the guide wire was reinserted into the sheath.A balloon was inserted over the viperwire guide wire to continue treatment, however the guide wire fractured.The fracture occurred due to the 45 degree bend in the 6 french sheath located near the proximal common femoral artery, which was due to the tortuosity of the superficial and common femoral arteries.A balloon was inserted into the sheath to trap the wire, and the wire was removed from the patient's body.Treatment to the peroneal artery was completed, and the procedure continued with oa treatment in the posterior tibial artery.There were was no patient harm.Per the physician, both the kink in the sheath and utilizing the viperwire guide wire as the primary wire caused the fracture event.Treatment with the oad likely exhibited stress on the guide wire at the kinked area, but there was no issue specifically with the guide wire or oad.
