The lifespan of an aortic stent can vary depending on a number of factors, such as the patient’s overall health and the specific type of stent used. In general, however, aortic stents are designed to be long-lasting and may remain in place for many years, even a lifetime. If a stent does cause problems, it may need to be replaced or removed. It is important that the stent is checked as part of a routine checkup.
