The reported adverse event/incident was investigated in alignment with endologix operating procedures and work instructions.Where possible, it is endologix practice to make at least three good faith efforts to retrieve a reported adverse event/incident related device as well as medical records and medical imaging.An evaluation of the manufacturing record was completed.A review of the part number/lot number combination needed for device identification shows the device to have been properly manufactured and released in accordance with the device master record.Endologix was unable to perform an evaluation of the device because it remains implanted in the patient.A clinical evaluation of the adverse event/incident was completed.An examination of medical records and/or medical imaging received by endologix shows right common iliac artery occlusion (with thrombus) with additional surgical procedure (right groin cutdown/ thrombectomy) complaints are confirmed.The buckled implant complaint is unconfirmed.This is moderately consistent with the reported adverse event/incident.The clinical evaluation also shows reasonable evidence to suggest type ii endoleak (of accessory renal artery) with additional endovascular procedure (coils) during index procedure occurred that was not included in the event as reported.The type ii endoleak was discovered during an examination of during review the operative note dated 03/08/2024.Device, user, procedure or anatomy relatedness of this complaint could not be determined.No procedure related harms were identified.The thrombus in the right common iliac artery stent created right iliac limb occlusion.It is unclear why the thrombus occurred.Type ii endoleak is anatomy related.The final patient status was reported as discharged to home on postoperative day five.No additional investigation of this reported adverse event/incident is planned.However, should additional information relevant to the investigation outcome become available, a follow-up report will be submitted.Endologix will continue to monitor this and similar adverse events/incidents.Corrections: g3- awareness date: updated.H6- medical device problem codes remove 1336.H6- investigation finding codes: removed 3233.H6- investigation conclusion codes: removed 11.
