Good Question: The largest abdominal aneurysm I have operated on was 16 CM in diameter. It is unusual these days to find really large diameter aneuryms due to better screening & due to the number found incidentally when exams such as sonograms or ct scans are performed for other reasons. Increasing size correlates with increased rupture rates.

Not sure of record..: The natural history of AAA is that they enlarge and rupture. The larger, the greater the risk of rupture. I have seen a patient with an unruptured AAA that was 10 cm in diameter. He was repaired urgently! hard to imagine that AAA can get too much bigger and not leak or rupture.
