Thank you for replying to my AAA question. My AAA was discovered in 2007 at a 3.7. Since then I have been having it checked yearly. Everything was the same until last year when it measured 4.0cm. I forgot to mention that I had it checked with a CT scan the first four years than he switched me to ultra sound because he said I was getting to much radiation from the CT 's. When it came up a 4.0 last year I was very upset but he said not to worry that he didn 't think it had changed because the CT test is so much more accurate than the ultra sound . I had my last test (ultra sound) last month and it came back 4.4 cm. I really freaked out. He was still not concerned and said he still dosen 't think it has changed from the 3.7 that it was in 2007. I am having a CT in 6 months for peace of mind. This was at my insistance. He wan 't to wait a year. What do you think ? Have you been having yours checked with CT's or ultra sound? My blood pressure is great , but my cholesterol and triglycerides are a little high. I take medicine.
