Radiation Therapy and Drug-Eluting Stents

Current Postings on This Page (12):

• Christine -- there is no such thing as a "radiation-coated" stent. There is a procedure called brachytherapy, in which a catheter is inserted and radiation is pulsed briefly. It was thought to reduce restenosis (a.k.a. reblocking of the artery) but in the most recent trials, it was no better than and in some cases worse than stenting alone. The two manufacturers of this equipment have ceased making it, although it is still used in very specific cases where it may be good.

• I have been told that the muscle tissue is coming through the stents I have which number 15 as of 2 weeks ago. I have heard that the radiation coated stents are better. What is your opinion?

• Anyone know of any institution that is currently using a completely biodegradable stent?? I know a Dr. Tamai did some research in Japan a few years ago, but cannot discover if anyone is currently using such a coronary stent with good results. Thanks G

• I had radiation therapy for a stent that reblocked after only 2 months. Unfortunately, it blocked again a year and a half later, as did the 2 other stents I had.

• Yes. Look over www.biocoats.com

• I think 80s is a time of PTCA, 90s is a time of stents, next decade is a time of drug-loaded (polymer) stents. The biodegradable stents are the last winner.
