A peripheral atherectomy procedure commenced to treat a plaque occlusion in the patient's distal left superficial femoral artery (sfa).A stent was reportedly present in patient's sfa region prior to the procedure, and the condition of the lesion within the patient's vasculature was reported to be in poor condition.The physician chose to use a spectranetics turbo elite laser atherectomy catheter to perform the procedure.To start the procedure, the physician used an ipsilateral access.However, the lesion was found to be very tight (severely narrowed) at the proximal sfa region.Attempt was then made to access the lesion from a retrograde approach, entering from the popliteal artery in order to cross the lesion.The physician finally could cross to 1cm from the stent's distal edge, using a knuckle wire technique with 0.035" guide wire.Afterward, using a microcatheter and other interventions, the 0.035" guide wire could cross to popliteal.Then, a 0.014" guide wire was used and the lesion was able to be crossed with use of the turbo elite device two times.Afterward, a drug coated balloon was used, dilated, and completed the procedure with no reported patient harm.However, on 18 august 2020 it was reported that an acute occlusion at the left sfa was confirmed by echocardiogram.Interventions were implemented and the patient experienced a prolonged hospitalization.In an email received on 21 august from the physician, he thought that there was no relationship between the acute occlusion and the turbo elite catheter.Although the turbo elite catheter was present in the area in which an acute occlusion was discovered, this event has been determined to be related to the procedure (the physician stated that the occlusion is a phenomenon that can occur, and it is unlikely that the use of this device was the cause) and to the patient condition (as mentioned before, the patient's lesion was in poor condition).
