Continuation of medical devices: information references the main component of the system.Other relevant device(s) are: product id: etlw1613c93e, serial/lot #: (b)(4), ubd: 05-nov-2014, udi#: (b)(4); product id: etbf3216c145e, serial/lot #: (b)(4), ubd: 31-oct-2015, udi#: (b)(4).Film evaluation summary: the reported bilateral limb kinking <(><<)>(><(>&<)><(><<)>)> angulation below the level of the flow divider was confirmed.However, the exact cause could not be determined from the films provided.The anatomy at implant is unknown, and earlier post-implant films were not provided for comparison.Ct¿s returned from 58 months post-implant revealed that an endurant cuff was seen positioned just below the lowest left renal artery, and ~10mm lower near the top of the aaa sac the proximal fabric of the endurant bifurcate was seen overlapping the cuff.There was ~10mm of remaining proximal seal length; however, no clear endoleak was seen within the 45mm diameter aaa either proximally or distally.The infrarenal neck was angulated at the flow divider ~65 deg a-p x 40 deg rt-lt; relative to the iliac limbs.The cuff/bifurcate aortic body were essentially straight; however, there was substantial acute limb angula tion observed near the level of the bifurcate flow divider.The origin of both the ipsilateral and contra limb were acutely angulated ~60 deg and 80 deg (respectively) at the bifurcate flow divider.The angulation occurred at the anterior-right side of the aaa, and resulted in a slight compression of each limb to a minimum flow lumen diameter of ~12mm (ipsi) and 9mm (contra).However, the stent grafts were patent with no appreciable thrombus, and no flow obstruction was observed distal to the limbs; bilaterally.It is possible that neck angulation and aneurysm morphology changes during the implant duration may have led to the observed acute limb angulation and resulting bilateral limb compression.However, the returned films do not show any obvious thrombus/occlusion which has occurred within or distal to the stent grafts, as a result of this bilateral stent graft compression.If information is provided in the future, a supplemental report will be issued.
