Data regarding the use under routine practice of abdominal aortic stent grafts in France are expected by the French National Authority for Health (HAS). Therefore, in its opinion report from July 13, 2010, HAS makes the maintenance of reimbursement approval of each stent graft dependent on the presentation of results of a specific follow-up study carried out in a cohort of patients representative of the French population treated under real-life conditions of use. This prospective cohort study must involve at least 150 patients implanted after registration on the LPPR (List of Products and Services qualifying for Reimbursement). The results of the follow-up study must be forwarded to the National Committee for Evaluation of Medical Devices and Health Technologies (CNEDiMTS) for examination once a year. The assessment of this follow-up could lead to the recommendation by CNEDiMTS to continue or stop the reimbursement of the concerned stent graft.
