Endovascular Repair vs Open Surgical Repair of Abdominal Aortic Aneurysms: Comparative Utilization Trends From 2001 to 2006

Treatment for AAA seems to be an example of the responsible use of new technology by physicians. The newer, less invasive, and less risky procedure (EVAR) is replacing the older and more invasive procedure (OSR) to a considerable degree. However, the overall combined utilization rate of both types of AAA treatment has remained stable in the Medicare population. There is thus no evidence to suggest that the introduction of the newer approach has led to the overtreatment of patients. Although radiologists do have a role in EVAR, surgeons strongly predominate.
