An endurant ii stent graft system were implanted for the endovascular treatment of an abdominal aortic aneurysm.The proximal aortic neck was between 16 and 19 mm, with a length of 33 mm and an angulation of 56 degrees.The arteries were reported to have numerous calcifications.It was reported that during the index procedure, due to the tortuous anatomy of the aortic neck, the physician attempted to advance the stent graft to follow the curvature of the artery.As a result, the stent graft was advanced proximally beyond the planned location, which resulted in occlusion of the lower renal artery.Patient was reported to be stable and no further intervention is planned.The physician commented: push-up was attempted to implant the stent graft for the purpose of following the greater curvature of tortuous neck.As a result, the stent graft was entirely migrated to upper side, which unexpectedly covered the lower renal artery.

(b)(4).Evaluation, results: inherent risk of procedure (vessel occlusion); unapproved use of device (proximal neck is less than 19 mm in diameter, neck angulation greater than 60 degrees); conclusion: known inherent risk of a procedure (vessel occlusion); off-label, unapproved or contraindicated use (proximal neck is less than 19 mm in diameter, neck angulation greater than 60 degrees).(b)(4).
