Event or Problem Description
The following information was reported to gore: on (b)(6) 2025, the patient underwent endovascular treatment for an abdominal aortic aneurysm using gore® excluder conformable aaa endoprosthesis and gore excluder®aaa endoprosthesis devices.Postoperative follow-up computed tomography (ct) revealed a type ii endoleak originating from lumbar arteries and a distal type i endoleak at the left distal side.On (b)(6) 2026, as treatment for the type ii endoleak, coil embolization of the right lumbar artery was performed.On (b)(6) 2026, for the distal type i endoleak, coil embolization of the left internal iliac artery was performed, followed by the placement of an additional stent graft extending to the left external iliac artery.Coil embolization of the left lumbar artery was also performed.Although the type ii endoleak persisted, it was decided to be monitored.Physician¿s comment: the length of the common iliac artery was originally approximately 2 cm, which did not allow adequate sealing zone of the leg device to the bifurcation of the internal and external iliac arteries.Consequently, the device migration may have occurred during postoperative follow-up.
