On a second read, it seems that they are doing two independent things:
- They fix your vein's stenoses, via normal angioplasty.
- They make a stem cell transplant, not for the veins, but to fix the brain lesions.
The text is confusing and I am not sure that this is what they mean, but for sure it makes more sense.
If this is the case, I would say that Dr. Fredman has some desertions on his side!!!
