(b)(6)study it was reported that vessel dissection occurred.The subject underwent treatment with the ranger drug coated balloons and eluvia drug eluting stents on (b)(6) 2022 as a part of the elegance clinical trial.The target lesion was in the left proximal superficial femoral artery extending to left mid superficial femoral artery with proximal reference vessel diameter of 2 mm and distal reference vessel diameter of 4 mm with lesion length of 140 mm and 70% stenosis.Prior to target lesion treatment, pre-dilatation was performed with 5 mm x 100 mm non-boston scientific drug coated balloon.Treatment of target lesion was performed by dilation with study devices, ranger drug coated balloon of 5.0 mm x 120 mm and 5.0 mm x 150 mm followed by placement of eluvia drug eluting stents of 6 mm x 80 mm and 6.0 mm x 60 mm, respectively.On (b)(6) 2022, post the treatment of target lesion with study devices, ranger drug coated balloon of sizes 5 mm x 120 mm and 5 mm x 150 mm, angiography was performed which revealed non flow limiting dissection of grade c in the proximal superficial femoral artery.Site confirmed, dissection was noted due to ranger drug coated balloon 5 x 150 mm.Subsequently, dissection noted was treated with the placement of two eluvia stents of 6.0 mm x 80 mm and 6.0 mm x 60 mm stents respectively in an overlapping manner and post dilated with non-boston scientific 5.0 x 100 mm balloon.Post treatment, angiography performed revealed no evidence of distal embolization or dissection and the final residual stenosis was unknown.On the same day, the event left superficial femoral artery dissection was considered resolved.However, post procedure was complicated by hematoma and acute blood loss anemia.Subject was found to be concerned and slightly diaphoretic with systolic blood pressure ranging between 76 and 122.Subject was transferred to icu setting for overnight observation.On (b)(6) 2022, the subject was discharged from the hospital with the further follow up to be performed on (b)(6) 2022.
