Event Description

The patient was treated for an abdominal aortic aneurysm (aaa) with the implantation of the alto abdominal stent graft system on (b)(6) 2024.Reportedly, during polymer fill, at 7 minutes there was under-filling of the contralateral gate.The physician inflated the integrated balloon causing the polymer to fill the contralateral limb.Soon after it was noticed that the polymer syringe had bottomed out.The patient became hypotensive.The anesthesiologist treated the patient with epinephrine, benadryl, and corticosteroids.The patient was placed on norepinephrine drip for another 15-20 minutes as the graft implantation was completed.The final angiogram showed a type ia endoleak due to underfilling of the rings.A 14 french sheath was placed and a non-endologix palmaz p4010 was placed using a 32mm cook coda balloon.This resolved the type ia endoleak.The norepinephrine was discontinued 15-20 minutes before the end of the procedure.The patient was hemodynamically stable.No endoleaks were present at the end of the case.Patient was transferred to the icu.The patient is neurologically intact, able to move all limbs and complains of some low back pain.Computed tomography scan performed on february 13, 2024, identified a large pair of patent lumbars causing a type ii endoleak (non-device related).No additional information has been provided.

Manufacturer Narrative

The reported adverse event/incident was investigated in alignment with endologix operating procedures and work instructions.Where possible, it is endologix's 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.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 alto, intraoperative type ia endoleak (resolved), filling problem, and hypotension complaints are unconfirmed.The type ii endoleak (anatomy-related) complaint is confirmed.This is moderately consistent with the reported adverse event/incident.The right common iliac artery diameter was 7.7mm, and the left common iliac artery diameter was 7.6mm (should be 8-25 mm) - off-label.It is unlikely this contributed to the reported events.The device, user, procedure, or anatomy-relatedness of this complaint could not be determined with the medical records available for review.The final patient status was reported as hemodynamically stable in the intensive care unit.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: investigation finding codes - remove code 3233.H6: investigation conclusion codes - remove code 11.
