How is the treatment performed?

You will be taken to the laboratory where the procedure to re-open the narrowed area within the graft is performed. The balloon angioplasty procedure will be performed to maximize the treatment of the beta radiation. The beta radiation sources are then delivered through a catheter to the treatment site where they will remain in place for a prescribed length of time, typically 3 to 4 minutes. The beta radiation sources are removed after each treatment, no radiation remains in the body.
