Manufacturer Narrative

The devices involved in this event will not be returned for evaluation and remain implanted in the patient.Patient medical records and imaging studies will be requested for further evaluation by a clinical specialist.If additional information pertinent to the incident is obtained, a follow-up report will be submitted.H3 other text : device remains implanted.

Event Description

The patient was being treated for an abdominal aortic aneurysm with the alto stent graft system.The patient had a short off label neck with a severe angle, making them unsuitable for a z-fen procedure.Despite challenges in imaging and device deployment due to the neck's angle, the procedure was successful in sealing the aneurysm.A post-procedure issue arose as the left renal was lost, possibly due to the migration of the ring or inaccuracies in marking.The patient is stable, and the case outcome, while successful in sealing the aneurysm, resulted in the loss of the left kidney.

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 device was not returned to endologix for evaluation because it remains implanted.A clinical evaluation of the adverse event/incident was completed.An examination of medical records and/or medical imaging received by endologix shows the alto, displaced implant with left renal occlusion complaint is confirmed.This is consistent with the reported adverse event/incident.It was reported that the neck was only 5mm long and it was highly angulated.This could have contributed to the reported event, but that could not be conclusively determined.The device, user, procedure, or anatomy-relatedness of this complaint could not be determined.The procedure-related harms were left renal infarction and conversion to brachial access.The final patient status was reported as discharged to home on postoperative day three in stable condition.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.
