What is the largest abdominal aortic aneurysm repaired?

Largest AAA repaired. You shouldn't think about it as, " is it too big to repair?" many anatomic details as well as a person's overall medical condition go into the decision as to if an aneurysm can be repaired. Its overall size is not a main consideration (though if its still small, they can usually be watched without repair).
Variable. People have various experiences. I was involved with repair of a 10cm AAA one time.
