It was reported that an occlusion occurred.Vascular access was obtained via ipsilateral advancing puncture.The target lesion was located in the occluded left superficial femoral artery (sfa).A 6x40, 130cm eluvia drug-eluting vascular stent system was implanted in the mid sfa two years prior.The lesion was approached with a 11cm non-boston scientific sheath, a non-boston scientific guidewire and a non-boston scientific microcatheter.As the lesion was stiffed, the opticross 18 device was switched to a different non-boston scientific guidewire and attempted to crossed through; the lesion was then confirmed using the device without any problem.The guidewire was then switched to a different non-boston scientific guidewire, and a coyote mr 4mm-150mm was used to pre-dilate the lesion and the plaque part before and after stenting.The opticross 18 device was then reinserted to confirm the need for treatment of the lesions before and after stenting, except for those in the stent; however, lost image has occurred during delivery.The opticross device was then removed and the procedure was completed with another of the same.There were no adverse patient effects observed.The procedure was successfully completed by treating the lesion part in the stent with peripheral cutting balloon (pcb).
