Mine is only 11 mm, which is much smaller than 1.4 cm. However, the vascular surgeon says if it gets any larger at all, I will need surgery. I asked him if he has ever performed this kind of operation, & he said "no". So I have another CT in 6 months, & if it is any larger, I'm gonna look into UT Southwestern in Dallas.They have a lot of vascular surgeons there, & maybe one of them has performed this operation. Dallas is 3 hrs away, & I've been there several times to a GI doc, & she and everyone else we came into contact with UTSW were all just amazing!
