beta radiation therapy
by Kiwi01, Feb 07, 2001 12:00AM
Dear Doctor,
I had a couple of stents implanted about 15 months ago and sveral months later they were blocked/blocking with cell growth and so I had bypass surgery. I have read about beta radiation therapy, a procedure they say clears re-clogged arteries in patients who have had angioplasty/stents. I have several questions: 1. Can this procedure possibly be used with me; why or why not, and is it wise to consider it? 2. What happens if the original arteries are opened if you have had bypass? 3. Do bypass arteries sometimes open on their own? 3. Is beta radiation therapy available at the Cleveland Clinic? Thanks for your help.

Dear vince,
Beta-radiation (also called brachytherapy) is the newest therapy for what is called "in-stent restenosis". There has been a lot of press about this recently because the FDA just approved a delivery device for this type of therapy. The therapy itself is still needs further investigation before it can be recommended for everyone. We are participating in ongoing trials of brachytherapy and those who are interested in this can call (216) 444-0770 for additional information.
In your particular case I don't think this therapy would probably not be a good idea because you already have the bypass grafts. If the grafts were to become blocked in the future you may be a candidate at that time.
Here are some review articles that have additional information.
In addition there is an article that was in the New England Journal of Medicine within the last few months that I don't have the reference for.
