Yep, 11 mm, not cm, which is much larger. When I asked the vascular surgeon if he had ever done the operation, and he said "no",, but I can't find you someone here who probably has. Not risking that. If the CT in 6 months shows that it is larger, I have a connection at UT Southwestern in Dallas, & they have about 12 vascular surgeons. I won't trust any dr here in Wichita Falls for anything! Our doctors are pathetic.I do keep having pain under my bottom left ri, but the dr said that's not where the aneurysm is located. Don't even know if he knows what he's talking about.Sometimes I wish I lived in a larger city. Dallas is 3 hrs away & OK City is too.
