An ovation ix iliac limb stent graft system was implanted to treat an abdominal aortic aneurysm.Approximately 3 weeks post index procedure, the patient presented with claudication and a cold left foot.A ct was done which showed one limb blocking the flow of the other limb leading to an occlusion.A re-intervention was performed where the physician attempted to balloon the occluded limb, however the patient could not tolerate the procedure and expired.

Based on the clinical assessment for this event, the most likely cause of the proximal loss of seal was found to be anatomy related, due to the hostile neck anatomy, which likely contributed to the occlusion of the aortic body, right iliac limb stent, and the native vessels down to the popliteal artery.The most likely cause of the occlusion within the stent was found to be the near complete buckling of the right iliac stent at the level of the bifurcation, however, the exact cause of the stent buckling could not be determined.The cause of the death or date of death could not be ascertained due to the lack of medical records surrounding the event.A review of the device quality records shows that the device demonstrated compliance to established procedures and specifications at the time of manufacture.
