It should be noted the gore® viabahn® endoprosthesis instructions for use (ifu) recommends that the endoprosthesis overlap the native vessel at least 1 cm beyond the proximal and distal margins of the lesion when treating stenotic or occlusive lesions.Additionally, the ifu states ¿complications and adverse events can occur when using any endovascular device.These complications include, but are not limited to: stenosis, thrombosis or occlusion.¿.

On (b)(6) 2019, the patient underwent an endovascular procedure whereby thrombectomy was performed, and a gore® viabahn® endoprosthesis was implanted in the right superficial femoral artery to treat acute limb ischemia.According to the report, patient had diffuse artery disease, and the condition of the vasculature including the right superficial femoral artery was poor.It was also reported that there was less than 1cm of healthy vessel seal zone on each side of the endoprosthesis.After the procedure on the same day, follow-up imaging reportedly identified occlusion of the right superficial femoral artery and the implanted endoprosthesis.On the same day, an additional thrombectomy was performed to repair the occlusion.Supplementary bare metal stents were also implanted at the both edges of the implanted viabahn® device to add radial force.The patient tolerated the procedure.
