Event Description

The patient was initially treated for an abdominal aortic aneurysm (aaa) with an afx bifurcated stent graft and vela suprarenal proximal extension.Approximately five and a half (5.5) years post initial procedure, the patient presented at routine follow-up with a fabric tear and a component separation; these observations are classified as a type iiib endoleak and iiia endoleak, respectively.The patient is reportedly asymptomatic.It is unknown if the physician plans to re-intervene.After the initial report, additional information was provided reporting that reintervention was completed with successful reline of the type iiib endoleak with an afx2 bifurcated stent graft and an afx vela suprarenal.The patient was reported to be doing fine post-reintervention.Subsequently, clinical assessment determined that the reported type iiia endoleak was refuted, and rather a type iiib endoleak of the bifurcated stent graft and proximal extension were confirmed.Additionally, there was evidence to reasonably suggest caudal movement of the proximal extension of 5.2mm occurred that was not included in the event as reported.The movement was discovered during a review of the 65-month post index computerized tomography scan.
