ascending aortic aneurysm 4.9 to 5.0 cm

Unfortunately, I don't think anyone can tell you, not even your doctor, though his/her guess will be worlds better than anyone on this message board. (I'm assuming you meant "without" rupture or intervention.)

There is data out there on risk of dissection/rupture versus aneurysm diameter. Your doctor should be able to give you that population-level data, FWIW. Medicine doesn't have a way to predict that for any individual yet. WRT growth rate, I believe that is non-linear and equally hard to predict. Scaled for your height, I'd guess some doctors might consider a repair now. Some doctors wait for 5.5cm. There is also population level data on growth rates.

So your doctor can give you real data on your odds. Whether they would stick their neck out and try to make a guess based on their experience probably depends on the doctor. It's a conversation worth having.

Having lived with an aneurysm and high CAC for a few years now, one question I'd ask myself is how would the answer change what I do?

I hope it goes well for you.

@bitsygirl Thanks, you are absolutely correct in your assessment. Bypass surgery was due to high CAC, and not everything was fixed in 6 hours. The question I posed is almost rhetorical but not cynical. I am early in the process after 6 months and 2 measurements for a new issue, plus the old ones.

I had a double bypass on the LAD following a ligation of 2 complex coronary fistulas and aneurysm on the right coronary artery. that took about 7 hours. We had a plan for the ascending aorta and aortic root, but the surgeon and I thought it was too much that day for the 4.7cm ascending aorta and 4.8cm aortic root. We had a plan for 3 different scenarios for the aortic stuff. He had it on the O.R. board and the material available but weren't going to do it unless he had to open the aorta to fix the other stuff. They had me off the bypass machine and heart restarted checking me for stasis. Everything looked good until the root started seeping blood and ruptured while the surgeon was checking things out. He had 2 fingers in the hole for 7 minutes while they got me back on the bypass machine. I lost 0.92 gallon of blood in the mean time. Surgery ended up 14.5 hours that day following 3 major procedures then the Bentall procedure. I was under anesthesia for 27 hours. My surgeon got to see what happened to John Ritter and Linsey Graham in real time.

@rlhix Wow. I have to think this was a rare combination of surgical skill, timing, and patient characteristics. Mostly surgical skill. Unreal.
