There are so many variables as to when to have the surgery. Each person’s body is unique. I am 5’3” and weigh 103 pounds, I just had the surgery in March. My cardiologist and surgeon said because of my size. It was best to operate on it at this time. My aneurysm was measured between 4.7 and 4.9 they also taken to consideration the rate of growth of the aneurysm, so as they say it’s not a one size fits all. I had my surgery done in Rapid City, South Dakota with an excellent surgeon. I was very pleased and am doing well.
