What are my chances of dying if my aneurysm ruptures?

Dr. Michael L. Schwartz, MD
Vascular Surgeon

If your aneurysm ruptures, the outcome could be lethal. If you make it to a hospital in time, your chance of survival is over 60 percent. You should have your aneurysm fixed when it is at a size at risk for rupture.

Once an aneurysm reaches 5 to 6 cm in diameter, the risk of rupture is very high. If rupture occurs, there is approximately an 80 to 95 percent chance of death. Therefore, the majority of vascular surgeons would agree that a 5 to 6 cm aneurysm should be repaired immediately, unless other medical factors make surgery risky.
