Elsie; welcome, if this is new for you here; please forgive me if I missed earlier contact from you.
Please ask your neuro about the options, including Pipeline (PED)...as I understand it, it was FDA approved for ICA implant; it is stent, but that coils are not needed.(?) Please check the Pipeline Group site for their responses.
You can view the FDA site by browsing the product #'s; H020002, H50001, H060001 and P100018; there are more that will show up on the FDA site by year order.
You are blessed to have been diagnosed early. Was that from symptoms or from the potential genetic issue?
Today's Mayo Clinic On-line Newsletter has an article on the beneits of CT scans, w/a small increase in radiation over standard x-rays, as they give a more detailed diagnosis.
W/o a doubt on that; what we are missing is data on the higher level of radiation on CTAs, MRAs, Arteriography Angios. Yet awaiting answers on those for our BAF group and the public.
Even in finding the Arteriography Angios in searches, they list the cardio, not the cerebral. So can assume it would be the same level in the brain as the heart...but would be so great for the specialists, the scientists, to tell us; because the heart angio is a high level of rad.
Another member, Julie, recently noted here the data on the need for those with clips to also have f/ups (tho perhaps not as frequently needed as post-coiling ?.)
Prayers that you get your questions answered by your doctor before you finalize your right and comfortable decision for you.
