title: Aortic endograft migration.
abstract: Despite the popularity of endovascular repair of abdominal aortic aneurysms, important issues regarding its long-term efficacy and durability remain. Many hemodynamic and biomechanical forces interact between the endograft, its attachment systems, and the aortic wall. Migration is the longitudinal movement of all or part of the stent-graft. When the magnitude of this displacement is such that endograft seal is lost, repressurization of the previously excluded aneurysmal sac can result. This can lead to catastrophic consequences. In this article, we review the definition, prevalence, diagnosis, clinical implications, and management of stent-graft migration.
