If you are referring to scar tissue build up inside stents, radiation therapy is useful for that problem, much moreso than laser therapy. It is still a relatively new procedure, and the long term safety is unknown. However, the short-term results appear promising.
Dear Dr: Thanks for your reply on my problem of scar tissue.I live in new york(Long Island) and was wondering where I could go to get more information on the radiation therapy you talk about?Is there any place close to me?
Lenox Hill Hospital in Manhattan is capable of doing this procedure.
Dear Dr: Do you know how long lenox hill hospital has been doing this procedure?Do you have the name of a doctor to contact?
As the procedure is relatively new, no one has done it for long - that is part of why there is a degree of uncertainty if you undergo this procedure. You can ask for an appointment with one of their interventional cardiologists.
