Abdominal Aortic Aneurysm Repair 
Abdominal aortic aneurysm repair is one of several high-risk procedures assessed by the Leapfrog Group. An abdominal aortic aneurysm is an abnormal ballooning of the abdominal portion of the aorta, the major artery from the heart. Leapfrog criteria include procedure volumes - that is, how many of a given type of procedure a hospital performs. Leapfrog emphasizes volume measures because studies have shown that providers who perform a high volume, especially of high-risk procedures, tend to have better outcomes. This is a measure of how close each hospital is to meeting The Leapfrog Group’s volume standard for this procedure.
