The complaint device was not returned for evaluation.Additional information and medical imaging was requested and to date, no response has been received.The work order record was reviewed and appeared complete and correct.There were no non-conformances raised or temporary deviations effective at the time of manufacture.Photographs taken of the graft during manufacturing were reviewed and the graft appeared to have been manufactured as per the fenestration layout.The instructions for use supplied with the complaint device states: "the long-term performance of fenestrated endovascular grafts, including the stents placed in fenestrations/scallops, has not yet been established.All patients should be advised that endovascular treatment requires life-long, regular follow-up to assess their health and the performance of their endovascular graft.Patients with specific clinical findings (e.G., endoleaks, enlarging aneurysms, changes in the structure or position of the endovascular graft, or stenosis/occlusion of vessels accommodated by fenestrations) should receive enhanced follow-up." "after endovascular graft placement, patients should be regularly monitored for perigraft flow, aneurysm growth, patency of vessels accommodated by a fenestration/scallop, or changes in the structure or position of the endovascular graft.At a minimum, annual imaging is recommended, including: 1) abdominal radiographs to examine device integrity (separation between components, stent fracture or barb separation) and 2) contrast and non-contrast ct to examine aneurysm changes, perigraft flow, patency, tortuosity and progressive disease.If renal complications or other factors preclude the use of image contrast media, abdominal radiographs and duplex ultrasound may provide similar information." "potential adverse events that may occur and/or require intervention include, but are not limited to: aortic damage, including perforation, dissection, bleeding, rupture and death; arterial or venous thrombosis and/or pseudoaneurysm; death; vascular access site complications, including infection, pain, hematoma, pseudoaneurysm, arteriovenous fistula, dissection." based on the information present a definitive root cause of the complaint could not be determined.
