The following information was reported to gore: on (b)(6) 2021, the patient underwent an endovascular treatment using a non-gore fenestrated stent graft (valiant) for an abdominal aortic aneurysm.Gore® viabahn® vbx balloon expandable endoprostheses (vbx device) were to be implanted in the right renal artery.It was reported that there was stenosis at the ostium of the right renal artery.After a guidewire was cannulated into the right renal artery and the true lumen of the right renal artery was confirmed by angiography, the vbx device was inserted.While advancing the vbx device, the guidewire slipped out of the right renal artery into the sheath, therefore, the guidewire was again cannulated into the right renal artery.The vbx device was then implanted.After the implantation, the flow on the distal side of the vbx device in the right renal artery could not be confirmed by angiography.The cause of the occlusion was reported to be unknown.Considering the risk of rupture, no treatment for the occlusion was performed, and the patient was to be monitored with careful follow-up.
