Event Description

The patient was initially implanted with a bifurcated stent graft, a suprarenal stent graft extension and an infrarenal stent graft extension to treat an abdominal aortic aneurysm (aaa).Reportedly, post initial procedure on an unknown date the patient was identified with aneurysm enlargement and a suspected a type ii endoleak and a re-intervention was completed.Now, approximately 4.5 years post initial procedure another re-intervention for type ii endoleak was performed.Embolization on the lumbar artery via internal iliac artery was completed.A type iiib endoleak was identified with a computed tomography angiogram (cta).The physician elected to implant an additional afx2 bifurcated stent graft.The procedure was successfully completed and the patient was reported to be in stable condition.This event was previously reported under mfr # 2031527-2022-00018.On (b)(6) 2023 the patient was found to have a fistula between the duodenum and small intestines.The physician elected to explant all the afx stent grafts and replaced the abdominal aorta with a "y" shaped artificial graft.During the explant procedure, the physician found a hole (classified as a type 3b endoleak) in the original afx stent graft.The patient status was reported as stable post operatively.The explanted stent grafts are available for return.

Manufacturer Narrative

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.The review confirms there were no manufacturing or processing non-conformities identified that would contribute to the reported adverse event/incident.The explanted device was returned to endologix for evaluation.Endologix received one afx bifurcated stent graft for evaluation, which was shipped securely in a biohazard bag within a box.Upon receipt, blood and tissue residue were observed.The device underwent thorough decontamination, followed by a detailed visual analysis.During examination, a 5mm hole was identified at the base of the bifurcation, and stent struts were observed protruding through the graft material.This discovery confirmed the reported type 3b endoleak, attributed to the hole in the graft.A clinical evaluation of the adverse event/incident was completed.An examination of medical records and/or medical imaging received by endologix shows that the type 3b endoleak and duodenal fistula are unconfirmed.The explant is confirmed.This is moderately consistent with the reported adverse event/incident.There were multiple revisions of previously placed graft.This may have contributed to the reported event but could not conclusively be determined due to lack of relevant medical information (cautionary product usage).It could not be conclusively determined if the hole in the graft was explant damage, from the main body placed at index or the main body placed 12 january 2022.The hole may be the type 3b endoleak noted in a previous event reported on 12 january 2022.Device, user, procedure or anatomy relatedness of this complaint could not be determined.Procedure related harms for this complaint could not be determined.The final patient status was reported as stable postoperatively.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.Device iteration is afx with duraply.Corrections: d9: device available for eval has been updated.G3: awareness date has been updated.H3: device evaluated by mfg has been updated.H3: device ret to mfg for eval has been updated.H6: investigation finding codes: remove code 3233.H6: investigation conclusion codes: remove code 11.
