Depends on the anatomy of the aneurysm, not all aneurysms are the same. Some AAs come with an aortic dissection component that only the doctor/radiologist will be able to know about.

Both come in different shapes and sizes, most AAs come without a AD component; just depends on each individual case. Thickness and size of the artery wall is but one of many dimensions to be considered when assessing "danger" and what activities one would be safe doing.

That is the reason you are seeing conflicting views on this website.

If you are 80 and going strong, and trust your docs - you are your own person and can make rational decisions.

When and if an aortic aneurysm or dissection "goes" you will know it.
