The following was reported to gore: on (b)(6) 2018, this patient underwent an endovascular repair for a pseudoaneurysm of the right renal artery using a gore® viabahn® endoprosthesis with heparin bioactive surface.The procedure was concluded with no issues, and the patient tolerated the procedure.On (b)(6) 2019, follow-up computed tomography (ct) showed that the endoprosthesis had stenosis.The patient was asymptomatic.On (b)(6) 2019, a reintervention was performed to repair the stenosis of the endoprosthesis.Angiography and intravascular ultrasound (ivus) confirmed that the middle portion of the endoprosthesis had the stenosis of 40-50 % stenosed.Reportedly, the proximal and distal ends of the endoprosthesis had slight intimal thickening, but not requiring treatment.An additional gore® viabahn® endoprosthesis with heparin bioactive surface was implanted inside the pre-existing endoprosthesis to repair the stenosis at the middle of the endoprosthesis.Post-ballooning was performed, digital subtraction angiography (dsa) and ivus showed good blood flow and expansion of the endoprosthesis.The procedure was concluded, and the patient tolerated the procedure.
