Dear Barbara -
>Okay, now I'm curious, and have to butt
in...It's my understanding, and maybe I'm totally misinformed, because I haven't
been keeping up with medical radiation research in the last year, but I THOUGHT
that radiation WAS effective in preventing restenosis...Isn't that what the
Novoste Beta Cath systems are all about?
Brief answer - yes, both animal and human trials
have proven that relatively high doses of ionizing radiation (15-30 Gy to
tissues in the artery wall) can reduce the rates of occurrence of restenosis.
Issues related to long term side effects are not resolved at this time. Longer
answer available on request.
