Why is AAA dangerous?
If the aneurysm gets too big, then it can rupture, or tear, resulting in massive internal bleeding and death. Most people do not survive a ruptured AAA. Ruptured AAAs are one of the leading causes of death in the elderly in the United States – killing approximately 15,000 Americans each year. Therefore, as a known cause of death in the US, AAA is about equal to HIV/AIDS or several forms of cancer.
