I Am 57 Female - I'm 5ft 7in - Weight

i am 57 female - I'm 5ft 7in - weight 230 - this year - i had a chest x ray due to bronchitis - it showed something - so i went for a CT scan which found lungs ok - but i have a 4.4x4.2 thoracic aneurysm on the ascending aorta - 6months later i had a 2nd CT scan - it shows size unchanged - my drs plan right now is losartin/htcz 100/12.5, reduce weight(i have already lost 20lbs) - reduce salt and continue to momitor - he says surgury is too dangerous and should only be consider if it grows past 5-5.5 - i feel like a ticking time bomb - i have been reading a lot - but the open procedure is very dangerous and the minimally invasive one shows it still has problems with leaks - what other options are out there for me?
