It was reported that the patient had an in-stent restenosis of the left superficial femoral artery (sfa).The patient was enrolled in the imperial study on (b)(6) 2016 and the index procedure as performed on the same day.The target lesion was located in the left distal sfa, extending to the proximal popliteal artery with 100% stenosis and was 90 mm long with a proximal reference diameter of 4.3 mm and a distal reference diameter of 5.2 mm and was classified as tasc ii b lesion.The lesion was treated with pre-dilatation and placement of a 6.00 mm x120 mm study stent.Following post-dilatation, the residual stenosis was 0%.On (b)(6) the patient was discharged with dapt.On (b)(6) 2017, the patient visited the hospital for the study specific 12 month follow up.Dus was performed and revealed in-stent stenosis estimated between 50-70% in the left sfa.On (b)(6) 2018, 90% of the in-stent stenosis was treated with balloon angioplasty with 10% residual stenosis.The event was considered resolved the same day.
