Abdominal aortic aneurysm (AAA) repair mortality

Abdominal Aortic Aneurysm (AAA) Repair is the surgical repair of an aneurysm in the abdominal aorta that is done to prevent the rupture of the aneurysm. The diseased portion of the aorta (the portion with the aneurysm) is replaced with a tube made out of man-made material. The graft takes place of the diseased aorta, which allows blood to flow easily through it to the kidneys, legs and feet.

AAA repair is a technically difficult procedure with a relatively high mortality rate. Serious complications can occur, such as arrhythmias, heart attacks and death. While some patients have higher risks for complications than others, some complications may be preventable. A lower death rate may indicate that a hospital provides a higher level of patient care.

About this measure

Mortality rate is the statistical measure of the number of people who die. This measure tracks the percentage of patients who had a AAA repair and died. The second graph shows a trend over time for this measure.

Note: In this case, a lower number is better.
