The best treatment for an abdominal aortic aneurysm depends on a number of factors, including the size and location of the aneurysm, whether or not it is causing symptoms, and the age and general health of the patient. Many aneurysms can only be repaired with the open operation. While this is a major operation, the outcomes are generally very good. Other aneurysms may be candidates for either open or endovascular repair. Both approaches have advantages and disadvantages in this circumstance, and you should understand the pros and cons of both approaches before deciding how to proceed. We encourage you to discuss all of these factors and any other questions you have with your primary care provider and vascular specialist.
