You will have no problems with the angiogram itself assuming you don't have a
dye allergy or
kidney trouble. The challenge will be with whether or not they can find anything that can be treated. That depends on the vessels that were treated in the past as well as the condition of what you have left to work with. Is it safe to have...yes. Scar tissue? Probably not since it's been 11 years. Hope this helps. Jeff the nurse in Nashville.
