What kind of life time line would you give a 75 year old who have inoperable aortic aneurysm.?

My Father has an inoperable aortic aneurysm the size of 2 golf balls. What kind of life expectancy can I expect for him?

with good blood pressure management he may get as many yeras as he would have even if he did not have the aneurysm…it is very difficult to say and even the doctors can only give a guideline…there are several things that come into the equation…where the aneurysm is, ascending aorta, thoracic aorta, abdominal aorta??? how big it is…mine was 5 cm when I had it replaced with the dacron tubing…it was an ascending aortic aneurysm (the most deadliest if it burst).
His general health and lifestyle and his size all make differences to his life expectancy… His aneurysm could even possibly be inoperable because it is more dangerous for him to have the operation than live with it at present…which seems to say to me that he is in rather frail health at present…

I wish you and your dad all the very best…
