It is every individual’s decision but At 67 and healthy I would listen to your surgeons, age will start doing its thing to your body and the aneurysm will just get worse if it doesn’t dissect/rupture first. I had my Ascending AA repaired 5 years ago at 54 and 5.2 cm, I was in great health and shape, my surgeon gave me >99% chances of no complications, the stress of having a time bomb was way stronger than any fear about the surgery. When I was 14 years old my next door neighbor who lived alone collapsed on the side of his house, moaning in pain, I jumped the fence and struggled to get him to his bed while my mom called an ambulance. He passed 2 hrs later at the hospital from a ruptured Abdominal AA. That experience it’s ingrained in my mind, when my time came I did not doubt a minute, chose surgery as soon as it could be done.
I wish you all the best!!!

I agree, it is a horrible and difficult decision to make. I also struggled with it for 6 months. I was diagnosed with a 4.5 cm ascending aortic aneurysm 10 years ago. It has slowly grown to 5.2 cm. Last year my cardiologist and thoracic surgeon said I should have surgery, but I couldn’t make a decision. There is the real risk of a dissection. But, I feel fine and don’t have any symptoms and was trying to balance that against a very painful surgery recovery and months of disruption in my life, my wife’s life and my family’s life. Add to that the risk of complications from the surgery. Finally something my surgeon said convinced me. He said the aneurysm is not going to go away and will likely continue to grow which will increase my risk of a dissection. He also said the older I get the more difficult the surgery and recovery will be (I am 72 and in reasonably good health for my age). So I am having surgery on April 9th.
