Charbonneau P, et al. - In this multicenter retrospective cohort study of patients with at least one anatomic instructions for use (IFU) criteria violation for endovascular aneurysm repair (EVAR) undergoing either elective EVAR or elective open repair (OR) for abdominal aortic aneurysm, researchers compared the long-term survival of EVAR and OR. This study identified improved overall long-term survival with open treatment among patients with IFU violations when adjusted for important clinical variables and propensity to undergo EVAR vs OR. They recommend practicing caution when considering EVAR in evaluating abdominal aortic aneurysm patients with anatomic IFU violations.
