I can understand your concern about the growth of your AAA in one year. One thing to consider is what test(s) were used to measure the AAA? For example, was an ultrasound used one year and a CT scan the second year? Different tests can produce different measurements.

We have some discussions on Connect that you might find helpful. Here is the link, https://connect.mayoclinic.org/discussion/aaa-surgery/ and

I would also like to invite some other members of Connect, who have discussed AAA to this conversation. Meet, @acara, @cheryl66 and @kdh1.

Here is some information from Mayo Clinic's website, https://www.mayoclinic.org/diseases-conditions/abdominal-aortic-aneurysm/symptoms-causes/syc-20350688

As you have a concern about the growth, I would encourage you to phone your doctor's office and ask about it and if there is a need to be concerned. Also, remember that it is always your right to get a second opinion. Have you considered getting a second opinion to put your mind at ease?
