In brief: Very high if rupture

Rate of rupture: 5 to 6 cm is 5 to 15%; 6 to 7 cm 10 to 20%; 7 to 8 cm 20 to 40%.
Also if the aneurysm increases in size by 8 mm in a year the risk of rupture is high even if less than 5 cm. Hence not only is attention paid to the size but also the rate of growth. Once it ruptures the mortality rate is greater than 50%. The key is to repair before rupture either by surgery or stent graft.

In brief: Depends on size

The risk of rupture for aaas is associated with the diameter of the aorta.
Hear are some rough rupture risks... <5cm 3%/yr, 5cm 6%/yr, 5.5cm 7.6%/yr, 6cm 7-10%/yr, 7cm 25%/yr, 8cm 40%/yr. The risk of a major adverse event from an elective AAA repair is less than 3% (roughly). Eighty percent of people with ruptured aneurysms traditionally don't make it. These stats have improved w/ stents.

In brief: Abdominal aneurysm

Risk of rupture increases once the aneurysm reaches 5cm diameter such that the risk of surgical repair to avoid rupture is less than the risk of rupture at that point.
