Endovascular repair is increasingly used for ruptured abdominal aortic aneurysms (RAAAs). This study estimated the mortality rate for this approach. A review of 307 publications in English was performed. Thirty-four publications representing 1,200 patients with RAAA were deemed appropriate for analysis by weighted least squares regression. Of the 1,200 patients, 531 (44.3%) underwent endovascular aneurysm repair (EVAR). The average age was 74 years, and 13% were female. Aortouni-iliac grafts were used in 49.4% of patients, and 50.6% received bifurcated grafts. The technical success rate was 94.9%, with a mortality rate of 30.2%. The ratio of endovascular cases to the total number of cases strongly predicted the mortality rate (weighted coefficient -0.378, p< .0003). The mortality rate following EVAR of RAAA is 30%. A 3.8% reduction in mortality was found for each 10% increase in the percentage of ruptures repaired endovascularly at each center. These results are suggestive of a learning curve.
