Endovascular Repair Offers No Added Survival Over Open Approach in AAA

Endovascular repair of abdominal aortic aneurysm produces survival rates similar to the open-repair approach over the long term, according to a New England Journal of Medicine study, confirming earlier findings from two other groups.

The OVER investigators studied some 880 patients at 42 Veterans Affairs centers. Half were randomized to endovascular and half to open repair. After a mean follow-up of 5 years, mortality from any cause (the study's primary outcome) did not differ between groups. There was a survival advantage among those younger than 70 versus older patients.

In Journal Watch Cardiology, Beat J. Meyer concludes: "Although endovascular repair does not yet offer a long-term advantage over open repair — particularly among older patients — the procedure continues to improve and is now an acceptable alternative for many patients."
