On (b)(6) 2019, this patient underwent endovascular treatment using gore® viabahn® endoprosthesis with heparin bioactive surface in the left superficial femoral artery.It was reported a viabahn was implanted approximately 7-8cm distal from the origin of the left superficial femoral artery.Additionally, one eluvia drug-eluting stent (6mm×4cm) was attempted to be implanted from the origin of the left superficial femoral artery.However, it was reportedly implanted 2 cm distal from the origin of the left superficial femoral artery.It was reported to bridge the remaining gap between the two devices, an additional eluvia drug-eluting stent (6mm×8cm) was implanted.Intra procedural imaging identified there was stenosis around the distal end of viabahn.Reportedly as there was blood flow blood flow through the device, the physician decided to monitor the patient without any additional treatment.On b)(6) 2019, an occlusion of the viabahn was reportedly observed.On (b)(6) 2019, this patient underwent additional treatment.It was reported urokinase could not be used because the thrombus was solid more than expected.As a treatment, a viabahn (5 mm × 25 cm) was placed to cover the stenosis, and then a viabahn (5 mm × 10 cm) was overlapped at the sfa origin (within the eluvia stent).Post ballooning was reportedly implemented at the edge of the device.It was reportedly an improvement of blood flow was confirmed.The physician reportedly stated at the index procedure, there was stenosis identified on the distal side of viabahn.Reportedly the stenosis most likely caused the post operative occlusion.
