Event Description

This report is related to mdr number 3011632150-2023-00104.The patient was treated as part of the mimics 3d usa post-market observational study.On the (b)(6) 2022, the patient was implanted with one biomimics 3d (bm3d) stent, a 6.0 x 150 mm stent which was used to treat a restenotic lesion of the superficial femoral artery (sfa) middle third in the left leg.A retrograde approach was used and the lesion was prepared using pre-dilation with percutaneous transluminal angioplasty (pta) balloon and atherectomy.The treated segment was also post-dilated with pta.On (b)(6) 2022 an additional 6.0 x 125 mm bm3d stent (the subject of this report) was placed in the sfa middle third to proximal popliteal to treat a restenosis.The site reported that on (b)(6) 2023, a restenosis of treated segment (target lesion) was identified.The device relationship was reported as possibly related and the procedure relationship was reported as not related.It was reported as target lesion related and required percutaneous intervention.The patient presented for her 12-month follow-up visit on (b)(6) 2023.She had recurrent claudication symptoms and ischemic rest pain in her left leg.An ultrasound showed some areas of in-stent restenosis as well as a decreased ankle brachial index (abi).On (b)(6) 2023 an angiogram was performed on her left leg which showed a stent present about 6 cm below the origin of the sfa.There was a high-grade stenosis just above the stent and diffuse in-stent restenosis was noted in the stented segments of the vessel which extended from the sfa proximal to the proximal popliteal artery a short distance above the knee.The patient had pta/standard balloon angioplasty and laser atherectomy on the sfa proximal third to distal popliteal on (b)(6) 2023.Completion arteriogram showed brisk flow through the entire treated segment with no evidence of residual stenoses.The patient was discharged in a stable condition.The outcome was reported as resolved/recovered.It was reported as a target lesion revascularisation (tlr) and target vessel revascularisation (tvr).The devices remain implanted.
